Classification of Skeletal Muscles
Several criteria were given for the naming of muscles. Match the criteria (column B) to the muscle names (column A). Note that more than one criterion may apply in some cases.
Column A
gluteus maximus
relative size of the muscle
adductor magnus
action of muscle
biceps femoris
number of origins
transverse abdominis
direction in which the muscle fibers run relative to some imaginary line
extensor carpi ulnaris
action of the muscle
trapezius
shape of the muscle
rectus femoris
direction in which the muscle fibers run relative to some imaginary line
external oblique
location of the origin and/or insertion of the muscle
