MEDICAL PHYSIOLOGY

Detailed explanation-1: -The prime movers (agonist) for hip flexion are the: Psoas major muscle, a long, tapering (fusiform) muscle that originates at either side of the spine and inserts at the lesser trochanter of the femur. The psoas muscle contracts when the hip is flexed.

Detailed explanation-2: -For example, the agonist, or prime mover, for hip flexion would be the iliopsoas. Although it does not work alone, iliopsoas does more of the work in hip flexion than the other muscles that assist in that action.

Detailed explanation-3: -The iliopsoas muscle is the strongest hip flexor and assists in external rotation of the femur, playing an important role in maintaining the strength and integrity of the hip joint.

Detailed explanation-4: -Commonly called iliopsoas muscle. This complex muscle system can function as a unit or intervene as separate muscles. It is essential for correct standing or sitting lumbar posture, stabilizing the coxofemoral joint, and is crucial during walking and running.

Detailed explanation-5: -The iliopsoas muscle is the major flexor of your hip joint. It’s made up of three muscles: the iliacus, the psoas major, and the psoas minor. These muscles work together to flex your hip, as well as stabilize your hip and lower back during activities like walking, running, and rising from a chair.
