Musculus adductor brevis

The video tutorial explains the innovation and function of the adductor brevis muscle, part of the adductor group of hip muscles. These muscles extend between the pelvis and the thigh, shaping the inner thigh. The adductor brevis originates at the anterior surface of the inferior ossis pubis ramus and inserts at the linea aspera. It is innervated by the anterior ramus of the obturator nerve, originating from the lumbar plexus. The muscle functions in the hip joint, supporting flexion and external rotation.
