Anatomical terms of muscle]

The adductor brevis is a muscle in the thigh situated immediately

flexion of the thigh when running or against resistance (squats, jumping, etc.).[2]

Structure

It is somewhat triangular in form, and arises by a narrow origin from the outer surfaces of the body of the pubis and

obturator externus
.

The Adductor brevis muscle widens in triangular fashion to be inserted into the upper part of the linea aspera immediately lateral to the insertion of pectineus and above that of adductor longus.

Relations

By its anterior surface, the adductor brevis is in relation with the

.

By its posterior surface with the

obturator artery
, the obturator vein, and the obturator nerve.

By its outer border with the

obturator externus, and the iliopsoas. By its inner border with the gracilis
and adductor magnus.

It is pierced near its insertion by the middle perforating artery.[3]

Innervation

The adductor brevis is innervated dually by the anterior and posterior branches of the obturator nerve.[4]

Function

The muscle is primarily known as a

hip flexor
. Whether it acts to rotate the femur laterally or medially is dependent on position.
