Musculus psoas minor

The video tutorial discusses the psoas minor muscle, a small and inconsistently present muscle in the inner hip. It covers the muscle's origin, insertion, nerve supply, and function. The psoas minor is absent in about 50% of the population, and when present, it originates from the 12th thoracic and first lumbar vertebrae. It is innervated by the first three lumbar nerves. The muscle's main function is to stabilize the pelvis and hip joint and assist in trunk flexion. Due to its intra-abdominal location, palpation is not possible.
