Much of the work of the body depends on the contraction of skeletal muscles. In this experiment you will first observe the characteristics of muscle contraction and then will investigate the effects of two factors -temperature and fatigue - on the action of your muscles.

How do muscles work?
Agonist vs. Antagonist. Muscle pairs: Muscles are grouped together in pairs on your skeleton Relaxed or contracted: When one muscle of a pair contracts, the other relaxes Pulling muscles. Skeletal muscles only pull in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the ...

You have now seen how big muscle groups work. We know that muscles contract and get shorter, but what does that really mean? How is it possible that our muscles constantly change size? Imagine you could explore deep into the structure of a muscle. You zoom in on the fiber and focus on the smallest muscle unit, the sarcomere.

The external work of a muscle is the product of the force it exerts on an object by the. distance over which it moves the object. The work performed by the muscle can be. calculated using the following formula: W = D x L. where D is the distance in cm, L is the weight of …

Muscle contractions can be slight or vigorous depending on work to be done and thus innervation Energy for muscle contractions-needs to make ATP: Direct phosphorylation of ADP by creatine phosphate(CP)-found in ____________________but not other cell types.As ATP is used,reactions between CP and ADP generates more ATP.(CP supply quickly exhausted
