Our body has over 640 skeletal muscles that make up the bulk of our body and more than half of its weight.  There are three types of muscles in our bodies: involuntary (smooth), cardiac, and skeletal (striated).  While there are distinctions among the different types of muscles, they all have the ability to contract, relax, be excited by a stimulus, and return to their original size and shape.
