FEMUR

FEMUR

--femur: body's longest & heaviest bone

--head fits in acetabulum; fractures in the neck are the most common cause of a "broken hip"

--greater & lesser trochanters for muscle attachment (2 gluteal muscles insert on the greater trochanter)

--on the posterior side, the gluteal tuberosity (where the gluteus maximus inserts) and the linea aspera (where the adductors insert) are distal to the lesser trochanter

--lateral & medial condyles articulate with the lateral & medial condyles of the tibia; the regions proximal to the condyles are the lateral & medial epicondyles

--you can palpate the greater trochanter & the 2 epicondyles

--patella: kneecap; the largest sesamoid bone in the body (a bone that develops within a tendon; there are others that you can palpate at the distal ends of your first metacarpel & metatarsal)


--if you stand up and lean forward, you can move your patella back and forth because your rectus femoris is at rest
