Document Summary
When you sit your iliac becomes tight: psoas major - spine to leg, originates on the bodies of lumbar vertebrae, pectineus- minor flexion function, sartorius- lateral side and crosses over medial. Hip extensors: gluteus maximus (superficial)- but muscle, hamstring group, bicep femoris long head, short head, semitendinosus, semimembranosus (under semitendinosus) Insert on the linea aspera of femur: originate on the pubis, adductor magnus, adductor brevis- more superficial than longus, adductor longus, pectineus. Hip abductors (away: originate on iliac crest. Insert on top of greater trochanter: gluteus medius (more superficial, gluteus minimus (deep, lateral rotators- deep under gluteus maximus.
