I'll go ahead and get started where the second day into the muscular system today yesterday we talked about the different types of muscle tissue remember we talked about three different types of cardiac visceral and skeletal we talked about some characteristics of muscles we talked about on some major muscle so we started on the muscular system and today we're going to they have a little bit different going to a little bit about how you keep that muscles going and how you keep them flexible and things like that especially when there's disease or injury involved real quickly will you we always go over a few bellringer information on last week with his questions a lot this week we're at least so far we've been looking at some terms again so remember these terms are terms that you can hear again to be responsible for once we go over you should earliest that everyone had a copy of its own Candace whatever that tells all the turn I recommended that you highlight the ones we've gone over so is she as you study you can look over and make sure you know the highlighted ones are riding down in your notebook 8 the latest has the definition and of course we go over it in here first prefix we're going over today is an t a n t e if anybody has your list in front of you or anybody that one is a when the gas song Anybody have an idea what that might mean that actually means before like interior before so ante is a prefix that before Melanie Melanie is a prefix think we're in town earlier we're not talking about a watermelon we're talking about melon as a prefix Mela you think of when you hear that Mala anybody should I Endure you have a guest I mean it's okay to say I don't know what you said again it's a prefix you want to guess what that might mean if you think of any lan can you think of a word that might a medical term that might go along with that that we might have talked about you may not that phone Snowman live now are there go ahead K I mean black melanoma remember if you remember anything about and you really hadn't studied it but if you've heard anything about a melanoma which is a type of skin cancer it's a black looking discoloration mole looks like a mole a lot like a regular Mo that people all the sudden see and they go get it checked out and it can be a type of skin cancer called me on Mama so black your right eye Squam Squam is another one and that's another one that it's really hard for you to guess because it doesn't didn't really sound like anything if you have your list but it means scale scale then a couple of a boy she have a clue to guess what capital b capital M is an abbreviation for you hear it medical all the time they say them blood pressure no bowel movement BM that that is an abbreviation is used for Bounty I'm sorry okay then we some of the abbreviations that we've used different ones on when things happen or Q2 day and things like that I'm today we're looking at Q with the letter with the number to q2h I guess what that would stand for q2h Q usually is Loosely like every every two what would you think 8 hours right every two so if they say give this I turn this patient q2h is what you see on your record you would know that you're supposed to turn that patient every 2 hours the last one is two 8s every AHS every night every night at bedtime I was told HS means an hour of sleep hour of sleep so give that are do that every night at bedtime and Sylvester Stallone a review of ours auntie Alan Squam BM q2h and qhs so that's kind of adding to our on abbreviation list and move it on through what abbreviations are muscular system a little bit remember yesterday we talked about muscles we talked about the different kinds of muscle we talked about how you have cardiac muscle which is a muscle that is located where where is cardiac muscle and that muscle contracts and when that muscle contracts and relaxes what does it make the heart do what actually makes your heartbeat what what causes that movement in your heart visceral or smooth muscle is a muscle that was found where did we say it was found a lot feel like she's working veins were right inside veins inside organs it's a smooth muscles that kind of works Issa as a liner almost though it's it is a smooth muscle are what we call involuntary what does involuntary mean it makes you didn't have to lay awake at night and stay awhile and I'll make sure my my heart still be let me let me let me relax that muscle and contracted muscles are you sure you don't have to do anything to make you happy that I'm and then you have skeletal muscle and skeletal muscle what is it day it holds what together along with connective tissue it holds your bones together doesn't and it makes your bones move I-69 has joined us hello hello you got it she was having trouble getting that link to work but that that holds your bones together and it allows them to move when those muscles relax or contract joints move your arms move otherwise I told you yesterday you just be kind of like slumped over there in that skeleton you become like him your arms and be flight but you wouldn't be standing upright iron Rod just making him stay that right without muscles without the skeletal muscles you just pump to the floor and just feel collarbone and it's not involuntary it's but I guess that means that you you are unless it's a reflex or something function makes you jump you are you have to think about it you know I'm bad about my hands here but I think about moving my hands I move them it's under voluntary control so I'm moving and those are just a few no muscle fibers muscle is fibers held together by connective tissue that holds things together and that's actually what helps your skeletal muscle it makes you move Breeze review I'm in case you missed it yesterday or just to think if you hear it over and over and help you remember it better we talked about characteristics of skeletal muscle we said one of them was anybody can remember any of them may not remember the word but some of the things that they do do I have any any recollection of it reason I won't you take a little time chapter today when we give you a time excitability remember they just have the ability to to to respond to a stimulus of a nerve impulse goes to them that they haven't excitability sorta kinda irritates and they they get excited and they can practice whatever contract ability that muscles has the ability when impulse goes to it to contract contract what does it do does it get longer or shorter contrats does it get longer or does it get shorter do you get shorter Grafton is getting shorter and thicker and the other opposite of x stability and that's where it gets longer and thinner so it can it gets excitable with an Impulse coming to it it either that can get shorter and thicker or extend and get longer and thinner and that of course is what makes those bones move on if you put your arm down getting longer and thinner then you pull your arm up what is contrasting is getting shorter and thicker think about that 30 then elasticity what is elasticity we compared it to a ask elastic that you know maybe had a lot of work out to the allow it to do elasticity helps it to go back in whatever position it needs to if that muscle stretches out if it was elastic it wouldn't be able to come back together and contrast and get shorter it so it keeps that elasticity which allows it to to extend and contract so can move about so that's what carries on movements and that's the characteristics your muscles has to have to be able to cost at movement if you want to think about it like that we talked about some major muscles not going to go back through them but as you study read through this chapter today in your extra time remember that on the about the 4th 5th page over there's a whole list of these muscles that we talked about yesterday there's a picture of a diagram that looks very much where you can see these muscles you can see the muscles that that happened when you extend your arm and the ones that are going to be affected when you contracted so you can action and extension in all of those things you can see those those pictures there some pictures of the different kinds of muscles that shows you what they look like so there's a lot of information to look at on that the meat of what we're really going to look at say we've already talked about these muscles produce heat energy they cost movement they help you maintain posture like we talked about that skeleton and it protects internal organs the thing we're going to look at today and we're going to go over is the difference things about muscles that help you move them I'm help you exercise them and help you work then we look at this we learned that there's a variety of different actions that a muscle can do that movements performed by these muscles happen then there's remember we talked about what is adduction do what was the key charm I told you always help me remember what adduction meant so now you remember adduction does what you got a gift so now you hear me what what what does adduction mean when here we talked about the different motions in it where I told you I always could remember adduction because of the prefix ad what is abduction when you're doing that duction move its got to guess you don't have to know just it adds back toward the body so Ed. can is actually moving a body part toward the midline of the body so if I do a deduction if I do I'm moving my arm this is abduction cuz I'm moving away from the midline of the body and this would be a deduction cuz I'm adding it back I'm moving toward the midline of the body so that's the way I always remember them adduction is moving toward the midline of the body and abduction is moving away from the midline of the body the other thing you can who is flexion you can decrease the angle between two bones so if I'm going to flex this mannequin hand arm he's going to move it just remember any time you're doing range of motion you're going to give me information on that little bit you're going to hold that phone above and below that joint that is extension so you're going to extension and then you're going to flexion you pull it toward the body and that's an example range of motion which we're going to talk about it a little bit in a minute is decreasing the angle between two bones are bending a body part we talked about flexing that arm and then extension was in chasing the angle-angle are extending the body parts rotation when you think of rotation you should think of your your neck basically and you rotate your head you are turn your heads turning a body part around its own axis and that's for example turning the head from side to side now rotation is side-to-side circumduction is in a circle you would move your arm like this to do circumduction because circumduction said give you the word Circle and that's how you can remember it circumduction is actually defined as moving in a circle at a joint or maybe in one end of a body part in a circle like this when the other part remain solid either way you're making a circle and rotation is just side to side so that some of the things that you can remember when using these definition along with how to how to move the body part I want you to see something briefly and then we're going to talk about it a little bit more and before we kind of gold guided notes a little bit that probably pretty much take our day but I want to share my screen and I want you to watch your short YouTube video with me this YouTube video is a lady doing I think she does a really good job showing range of motion and explaining range of motion in this city are you going to see her explain the watch this with me I'm going to your 8 today I'm here to help you with your all right the first thing I'm going to do is make sure that I've raced your bed up is good I'm going to start your shoulder exercises now start with flexion and extension of flexion roll your onto your side so I could do hyperextension of the shoulder now I'm going to do abduction and adduction abduction and adduction Spokane rotation of the shoulder rotation inward rotation rotation inward rotation always making sure that I have the upper are at a 90 degree angle from the body flexion extension flexion extension supination and pronation supination now we'll work on your wrist flexion extension and hyperextension flexion extension hyperextension trainer and I will do radial flexion Palmar flexion radio question radial flexion now I will work this up abduction adduction abduction flexion extension flexion extension adduction abduction at work each finger individually now I'm going to discussion an extension of the fingers flexion extension all right are you ready to work your like now I'm going to expose only one leg how do I start my working the hit the first thing I'm going to do flexion and extension flexion abduction at abduction Atwood rotation rotation I will work for me flexion flexion extension flexion extension next we move to the ankle plantar flexion plantar flexion plantar flexion dorsiflexion Haitian location application abduction adduction abduction spell individual flexion and extension of the toe flexion extension extension I will let recondition you for Comfort put the bed back in low position with the head of the bed at 30 degrees side rails up if ordered is there anything else I can do for you right now that thank you I'll go wash my hands recording report okay did y'all hear that pretty good that's pretty good demonstration of range of motion when they're talking about range of motion just so I know since I'm using a new device for y'all able to hear that okay and see it okay yes ma'am everybody still with me that was Kayden I should have let me see I have Alicia here now I have deshonta still here I cannot wait to see y'all still let you come out Alicia here here right yes ma'am Akira Julianne Julianne showing her that she's got off of meet you at I'll come back to her Sanaa okay a good deal she'll Andrea and is sometimes it takes you a little bit to get off here I'm here taniyah Williams and Julie so we watch that and you saw a little bit about range of motion and still a little bit about what what is going on with range of motion are y'all still able to see me I can't see myself right this second y'all able to see me I still see it okay can you take a mannequin over here pretty right now can you see it if I work with this mannequin how well can you see him like craft wait she did a lot of different movements but there's a couple that really are brought out in our texts and I wanted in our curriculum I want us to be able do it remember we talked about and one of the things you got to remember us when you're doing these range of motion drink and you got to keep your patients privacy you always think about your patient always watch your face you got to keep covered to the best you can't but remember when abduction was moving a part away from the body and adduction was moving it towards the body so abduction he doesn't have a lot of range of motion in shoulder sometime those are two of the things that she brought out that I want you to be sure and remember then they she used flexion when you hold it took on you do flexion and extension action and extension that is flexing the arm and extending on that's two more I'm remember she talked about our she did little bit we talked about she did the arm but rotation is when you turn the head from side-to-side anytime you're doing range of motion on a person be sure that there's no neck injuries or anything and be sure that you have specific approval to do the head and neck on sometimes it might be that you would just be cracked Rotation by rotating the wrist and remember the other one that we did was circumduction and that was a circle and she did that by making this body part like I told you this man's not his stuff but moving that arm in a circular motion are doing the whole arm in a circular motion so those are the primary ones that he wants us that the text says that I curriculum wants us to know I'm just the basics and also remember that by doing these range of motion exercises you're keeping these joints moving this is called passive range of motion the the passive Park have to do with what the patients able to do so the patient is not participating at all that's considered passive so passive range of motion is it when another person the caregiver is doing exercising and the patient is not doing anything he just laying there maybe, toes just maybe stop paralyzed unable to move this person could do it themselves with a little distance but I'm not much and I might would help you determine if they can you flex your arm can you pull your arm back towards your body the patient would pull it back towards the body and lay it down and I would just hope that patients are they active Ranger because that patient is actively involved in that movement in doing that so passive he's not doing anything active they're able to participate what happens if you are keeping those joints and those muscles able to move there not tightening up because if you don't move joints if you don't move muscles on face become tight and they they do what's called a trophy and they just kind of waste away or wake me up and you get contractures you get swear that patient cannot move or you couldn't even move them yourself there be so tight so that is what range of motion do you need to remember that active range of motion ocean actively Works those muscles cuz I'm working them that when I do passive range of motion on someone those muscles are are staying limber but it's not strengthen them moving them I'm actually work it's not an exercise so it's not as effective on muscles to do passive range of motion as it is to do active that's why it's a patient can participate active range of motion because that builds the passive range of motion is better than nothing by all means because it helps keep those muscles working and limber but it does not strengthen them and exercise you can't exercise for somebody they have two x so that's a little bit about that part as you study in this anatomy and physiology chapter under the muscular system you're going to cover all of these different things before we get off of here a lot more time if I try to follow my time limit today and give you a little time we talked about my scooter system guided notes some yesterday somebody Julianne or somebody pointed out there's a little problem with him and I think I fixed it went in there and fixed it so y'all should be able to go in there and do that they were up but it had the wrong kind of a box we talked about how many muscles over 600 we talked about the fibers being high together by connective tissue we described them to find what we just to find again excitability and contrast ability and extensibility and elasticity we talked about what was cardiac muscle what was visceral muscle what was skeletal muscle cardiac and visceral or involuntary skeletal is voluntary we talked about that the main function muscles was attached to bones to provide voluntary movement produce heat and energy and help maintain posture by holding the body erect and protected internal organs we talked about how if you hit somebody in the abdomen it would harm mower if they were someone who had no muscle tone there than it would somebody who had really worked out and had a lot of muscle cuz there's more muscle there to protect those internal organs but anybody muscles help protect internal organs to a certain extent we talked about we stop there but we also want to talk about the fact that skeletal muscles attach to bones and different weights some attached by tendons that's gotten no answer by tendons with your straw tough fibrous connective cards other muscles attached by faccia a faccia which is a tough sheet-like membrane that covers and protects the tissues the ones Accord the tendons are like chords and Asia is a is a sheet of membrane when a muscle attaches to a bone the end does not that does not move is called the origin and in that moves when the muscle contracts is call the insertion so it's the our origin maybe I'm doing this muscle here this is the origin that done contract but the end that moves would be called the insertion after abduction we talked where is moving the body toward the heart toward the midline remember this was abduction this is adduction abduction away from the midline adduction toward the midline we talked about flexion reflection as when you bandage for the body extension his when you stretch it out then we talked about rotation which was turning a body part on its own axis you can do it with the wrist if you have orders to you can do it with the head and neck circumduction is that circular movement if you could pull this little guy's shoulder out completely either way you would do the circular motion it's called circumduction range of motion somebody failed him on his range of motion exercises muscles are partially contracted at all times even when not in use is called partial fraction is called muscle tone and sometimes described as a state of Readiness so there's always muscle tone because those muscles are ready to act when muscles are not used for a long. Of time they can atrophy i t r o p h y which means shrink in size and lose strength and that is why it can also result in a contracture which is a severe tightening of a the resulting in bending of a joint will actually been that joint because you're not using it and that is why we're going to stop there because tomorrow we're going to get into diseases and abnormal things about the muscle and we will go there but that's another part of your guided notes but remember there's just a few left it will go over tomorrow but in this text if you using your time when you have a little extra time this this. You can find answers in this section about the muscular system in chapter 7 which is anatomy and physiology and you have these check this study and that's what I want you to read is all of that section on the muscular look at all these pictures you have diagram that looks very much like that you have different diagrams that you use this time to read this material and look at look at the pictures of the different kind of muscles look at the different kind of range of motion look at your major muscles on that diagram so you know where they are and you're able to understand them because that is material that we're covering during this whole unit take this time and work with your guided notes so you can be able to come in and work with these guided notes and have this because that is your assignment those things have to come back to me you have until midnight Sunday night but my goal is it your not off rushing around to get these midnight on Sunday that you're able to have these doing by the end of the week and and be done with it so that's my goal here tomorrow like I told you we are going to bench your own into how can about different kinds of diseases and disorders and injuries that you might have to the muscular system and related signs and symptoms are you at rated what you would do for IT some of the signs and symptoms and all of it how you prevent these things and just go into abnormal things about the the muscular system except for touching briefly on contractures we really haven't talked about anything that abnormal art movements what's normal and so we're going to get a little bit into abnormal things tomorrow and we've got that section will go over on her note plus you got it in your book if your use the time wisely that you left before your next class. You should be able to finish these guided notes and read that unit that section of this unit and you should be in good standing for the rest of the week you will have a lot of stuff to do as far as assignments and things I'm going to do some class work and stuff that you won't have as many assignments so that would be my goal buddy have any questions before I I want to go ahead real quickly and make sure I've got everybody accounted for cuz I don't have anybody is at since it might have been here any question okay just got if if if I don't call you don't have to answer me this time you've already spoken up when I ask but if I don't call your name out let me know just show play brownfields here Alicia Forrest I have present if your garden Julian Hall and I James to Andrea Martin caidin Ming and Kanaya Williams is there anybody on here that I didn't call out I don't want to count you absent if you're not asking alright I'ma let y'all go read the chapter assignment is to your hair send me anything unless you finish your guided notes now I do want you got and that's when they're completed their do you buy at least by Sunday night is Regis chapter this section on the muscular system and work on your guided notes OU familiar with that stuff look at all these pictures and stuff if I see that you're using this time and I'm getting your assignments quicker and we're not you're not struggling to get them in on time then I will know that this is a good practice to give you a little extra time if I give you the extra time and nobody gets their assignments in any quicker than I know you're not using that time wisely so we will go back to not doing it but I think it's a good idea if you'll use it wisely okay go in razor section and then I'm as you read it you can answer these guided notes and you can you can easily finish those up today you bet he has any questions reach out to me and let me know that's all I got for you today I will talk to y'all tomorrow body
