Adductor brevis muscle

The adductor brevis muscle is a muscle located in the thigh. It is part of the adductor group of muscles, which are responsible for the adduction of the hip joint.

Anatomy

The adductor brevis is situated in the medial compartment of the thigh. It lies deep to the adductor longus and superficial to the adductor magnus.

Origin and Insertion

The adductor brevis originates from the anterior surface of the inferior ramus and body of the pubis. It inserts into the pectineal line and the proximal part of the linea aspera of the femur.

Nerve Supply

The muscle is innervated by the obturator nerve, which arises from the lumbar plexus, specifically from the anterior divisions of the second, third, and fourth lumbar nerves (L2-L4).

Blood Supply

The adductor brevis receives its blood supply from the obturator artery and the deep femoral artery.

Function

The primary function of the adductor brevis is to adduct the thigh at the hip joint. It also assists in flexion and medial rotation of the thigh.

Clinical Significance

Injuries to the adductor brevis, such as strains or tears, are common in athletes and can result in groin pain. These injuries are often referred to as "groin pulls."
