Document Summary
Landmarks (anterior) asis, pubic tubercle, inguinal ligament, patella, enlarged ends of femur. Inguinal ligament = separation between thigh region & abdominal cavity; more prominent in pregnant women: during flexion, where joint is moving about (lateral) greater trochanter (posterior) ischial tuberosity and popliteal fossa. Ischial tuberosity = spot between gluteal region & seat that sitting on: popliteal fossa = increase range of motion when contracting; landmark for arteries and nerves (no muscle attachment here; but surrounding it) Muscle groups: anterior group (flexor; but some serve dual function, action = flexion at hip and extension at knee. Innervation = femoral nerve: adductor group (medial compartment, adductor longus, adductor magnus, adductor brevis, action = adduction and flexion of thigh. Innervation = obturator nerve: posterior group, action = extension at hip and flexion at knee. Innervation = sciatic nerve: abductors? (posterior region, gluteus medius, gluteus minimus (deep to gluteus maximus)
