MUSCLE LIST
HUMAN ANATOMY & PHYSIOLOGY

The following list of muscles includes those found in both humans and cats. The names in parentheses are cat muscles and those not in parentheses are human muscles. You are not required to learn parenthetical names. If only one name is given and it is not in parentheses then it has the same name in both humans and cats, but if a name is given only in parentheses it does not occur in humans, and is included only to clarify the cat dissection. Your responsibility is to learn human muscles on the cats, manikins and cadaver. The examination on muscles will include most of the cats in the laboratory, so it is necessary to study several cats. On the examination you will be asked only to give the names of the muscles and not their origin or insertion.
