Document Summary

Quadriceps tendon (goes into patellar tendon/ligament and inserts on the tibial tuberosity) All contents are funneled by the femoral sheath, a continuation of the transversalis sheath. 3 muscles insertion with fascial webbing in between: sartorius, gracilis, Femoral canal within the femoral canal, inguinal lymph can travel from external to internal pelvis. Open up in the abdominal cavity, creating a weak spot where the intestines try to push out. Gives off medial + lateral cx aa. , which provide blood supply to the head/neck of femur. Gives off perforating aa. to supply posterior thigh. Come to the medial thigh, passing through the adductor canal (formed from the fascia coming from the adductor muscles) They then come to the posterior knee through the adductor hiatus (formed from adductor magnus) and become the popliteal a. Travels with saphenous n. (the saphenous n. also travels through adductor canal but not through adductor hiatus it does not want to innervate posterior)

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
