Question

Quizplus · Accepted Answer

The iliopsoas muscle group, which is composed of the iliacus and psoas major muscles, is the prime mover of flexion of the thigh at the hip joint. This muscle group originates from the lumbar vertebrae and inserts onto the femur, allowing for powerful flexion of the hip joint. The other muscles listed (gluteus medius, tensor fasciae latae, and rectus femoris) all contribute to hip flexion but are not the primary movers.
