Document Summary
Excitability: responds to stimuli and acts differently because of the stimulation. Elasticity: stretches and returns to original shape. It"s primary function is to move the body. It also has the function to maintain and protect what is underlying the muscles (such as organs). It regulates body temperature; in fact, cellular respiration within the muscles produces heat the degree to which we are undergoing cellular respiration indicates our body temperature. When we are doing nothing, just sitting, our body temperature drops. Contracting muscle cells takes a tremendous amount of energy, atp. In fact, atp is necessary for both contraction and relaxation to occur. If you run out of atp while your muscle is contracted, you get a cramp and you are unable to get to the relaxed state. In the process of breaking down glucose (process of cellular respiration) both atp and oxygen are required. The product is co2, atp and heat is lost.
