Anatomy and Cell Biology 2221 Lecture Notes - Lecture 20: Lower Extremity Of Femur, Tibial Nerve, Common Peroneal Nerve
Document Summary
Anatomy 9501: ll lecture 7 ant. and post. Attachments: supracondylar line (distal femur) to post. calcaneous surface just med. to achilles. Attachments: post. fibular head, upper post. surface of fibula, and med. border of the tibia and unites w/ gastrocs aponeurosis to form the achilles. Attachments: med. femoral condyle (med. head), lat. femoral condyle (lat. head), and the. 2 heads unite into a broad aponeurosis into the achilles tendon. Action: flexion of knee and pf of ankle. Bent knee is just the soleus, knee straight gets both. Deep group = down the hatch (med. to lat. ) Attachments: post. fibula and lower interosseous m. b. , around medial malleolus, to the plantar surface of base of distal phalange of big toe. Action: flexes big toe, helps supinate ankle, weak pf. Attachments: post. surface of tibia (distal to popliteal line), post. to med. malleolus, to plantar surface of bases of 2-5th distal phalanges. Action: flexes toes 2-5 and helps w/ pf.
