flexes the thigh at the hip

Q. The psoas major muscle:

flexes the thigh at the hip

extends the thigh at the hip

adducts the thigh at the hip

abducts the thigh at the hip

assits in full contraction of the diaphragm

The psoas major joins the iliacus muscle, which originates broadly over the inner aspect of the iliac wing of the pelvis, to become the iliopsoas and insert on the lesser trochanter of the femur and flex the thigh at the hip.
