Adductor brevis

The adductor brevis (Latin: musculus adductor brevis) is a flat, small triangular-shaped muscle of the thigh that extends between the pubis of the hip bone and femur. It is found in the medial compartment of the thigh. Together with the adductor longus, adductor magnus, pectineus and gracilis muscles, the adductor brevis belongs to the hip adductor muscle group. It is the shortest muscle of the adductors.

Origin

The adductor brevis muscle originates from the body and inferior ramus of the pubis.

Insertion

The fibers of the adductor brevis insert on the femur - on the upper third of the medial lip of the linea aspera.

Action

The adductor brevis muscle provides the adduction, flexion and external (lateral) rotation of the thigh at the hip joint. Also, it stabilizes the pelvis.

Innervation

The adductor brevis is innervated by the obturator nerve (L2 - L4) that arises from the lumbar plexus.

Blood supply

The adductor brevis muscle receives arterial blood supply from the obturator and medial circumflex femoral arteries. The first artery is a branch of the internal iliac artery, while the latter arises from the deep femoral artery.
