I.+Muscular+Physiology

__ Application __
=== Meagan- As an OTA, it is important for me to understand how muscles work. I will need to know why muscles contract and why they relax. Along with this, I will need to know why muscles contract and relax. During my career as an OTA, I may be working with individuals who muscles will be contracted or have high tone, such as cerebral palsy. It will be my job to help the individual decrease the tone in the contracted body part. Just the same as if I am working with someone who has low muscle tone, I will be responsible for helping to increase their tone. === == Christine- As nurses we realize how important our muscles are to our patients. If our patients stay for long periods of time on bedrest it is our job to make sure that they do not get muscle weakness or lose function of their muscles. This may include getting the patient to do daily simple exercises to keep their muscles active or it may even mean doing these exercises for our patient if they are unable to do it themselves. == == Kalli- It is important for everyone to understand how muscles work because some of us take for granted what it is like to walk down to get the mail, write our names, or even brush our hair. As an OTA, I will need to understand which muscles move which parts of the body and how exactly that process works in order to explain it to my clients, and in order to figure out which part of the process we need to improve on. My clients will hopefully benefit from my knowledge of the musculatory system and I am determined to spread my knowledge among them in order to help them better understand what is going on inside their bodies. ==

__ The Steps of a Muscle Contraction __
==== The are many steps involved in order to move our arm, walk, or type on the computer. This video I have found on youtube.com shows each step clearly along with a verbal explaination including the proteins found in muscles, neurons, and the parts of the muscle affected. ====

=__ Essential Questions/Case Study __= ==// Describe the sliding filament theory of muscle contraction and why it is called the slideing filament theory. Describe the action of the cross bridges that cause a power stroke. What is the role of calcium and ATP in muscle contraction and relaxation? //==

I was struggling in finding a way to explain the sliding filament theory of muscle contraction because I didn't know where to start the explanation part. However, I found the perfect video to explain all the steps in the theory, the action of the cross bridges, and the role of Ca and ATP in contractions and relaxations. media type="youtube" key="0kFmbrRJq4w" height="315" width="560" []
