gluteus minimus muscle

Information about gluteus minimus muscle

Gluteus minimus
The gluteus minimus and nearby muscles
Structures surrounding right hip-joint. (Gluteus minimus visible at center left.)
subject #128 475
Origin:Gluteal surface of ilium, under gluteus medius.
Insertion:Greater trochanter of the femur
Artery:superior gluteal artery
Nerve:superior gluteal nerve (L4, L5, S1 nerve roots)
Action:Works in concert with gluteus medius: abduction of the hip; preventing adduction of the hip. Medial rotation of thigh.
Antagonist:lateral rotator group
The gluteus minimus, the smallest of the three gluteal muscles, is placed immediately beneath the gluteus medius.

Origin and insertion



It is fan-shaped, arising from the outer surface of the ilium, between the anterior and inferior gluteal lines, and behind, from the margin of the greater sciatic notch.

The fibers converge to the deep surface of a radiated aponeurosis, and this ends in a tendon which is inserted into an impression on the anterior border of the greater trochanter, and gives an expansion to the capsule of the hip joint.

Relations

A bursa is interposed between the tendon and the greater trochanter.

Between the gluteus medius and gluteus minimus are the deep branches of the superior gluteal vessels and the superior gluteal nerve.

The deep surface of the gluteus minimus is in relation with the reflected tendon of the rectus femoris and the capsule of the hip joint.

Action

The Glutæi medius and minimus abduct the thigh, when the limb is extended, and are principally called into action in supporting the body on one limb, in conjunction with the Tensor fasciæ latæ.

Their anterior fibers, by drawing the greater trochanter forward, rotate the thigh inward, in which action they are also assisted by the Tensor fasciæ latæ.

Variations

The muscle may be divided into an anterior and a posterior part, or it may send slips to the piriformis, the superior gemellus or the outer part of the origin of the vastus lateralis.

The Nutty Professor (1996 film) uses the words "gluteus minimus" as a buzzword for a "nice ass".
