Question

For muscle anatomy identification, you will need to identify thename of the muscle, the origin, the insertion, and the action ofthe muscle labeled on the models. You can find origins/insertionsin your lab manual, but you can also find the specific origins andinsertions we are looking for on the laminated cards for the claymodeling in lab. For actions, please identify the primary action ofthe muscle. For example for the gluteus maximus, the primaryactions are extension and rotation of the hip and maintain kneeextension. Many muscles also perform other actions in which theyare supporting other muscles. You do not have to include these,just focus on primary action. Please make sure you also know theindividual muscles of the iliopsoas, quadriceps, hamstrings, andpelvic floor.

iliopsoas (psoas major and iliacus)

gluteus maximus

gluteus medius

sartorius

adductor longus

adductor magnus

gracilis

quadriceps femoris (rectus femoris, vastuslateralis, vastus medialis, vastus intermedius)

hamstrings (biceps femoris, semitendinosus,semimembranosus)

pelvic floor (levator ani and external urethralsphincter)- NO origins and insertions assessed for thesemuscles, just identification on models and actions.

Flexor digitorum longus

fibularis longus (peroneus longus)

extensor digitorum longus

gastrocnemius

soleus

extensor hallucis longus

tibialis anterior
