Question

1.Name two muscles that insert on the lesser trochanter.

2.What is the primary action of the muscles that insert onto the lesser trochanter?

3.Name six short muscles that laterally rotate the hip.

4.Name two muscles that abduct the hip not including the tensor fascia lata. What is a second action of these muscles?

5.Which muscle performs lateral rotation of the hip, flexion of the hip and flexion of the knee?

Answer 1

1)Two muscles that are inserted on the lesser trochanter are psoas major, lliacus.

2)Psoas major function - flexion of hip.

Iliacus function- flexion of thigh and forward tilting of pelvis.

3)Six short muscles that literally rotate the hip are.

Piriformis,gamellus inferior,gamellus superior,obturator internus,obturator externus,quadratus femoris.

4)Hip abductor muscles- gluteus minimus,gluteus medius and tensor fascia lata.

The muscles are necessary for stability,they also help rotate the leg at hip joint.

5)The muscle.which performs the lateral rotation of hip are external and internal abturators,inferior and superior gamellus, piriformis, quadratus femoris.

The muscles which performs flexion of hip are iliopsoas mucles which are psoas major and iliacus.

The muscles which performs flexion of knee are hamstring group muscles which are semitendinosus,biceps femoris and semimembranosus.
