Encyclopedia > Gluteus minimus muscle
Gluteus minimus
The gluteus minimus and nearby muscles
Structures surrounding right hip-joint. (Gluteus minimus visible at center left.)
Gray's 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

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 ilium of the pelvis is divisible into two parts, the body and the ala; the separation is indicated on the internal surface by a curved line, the arcuate line, and on the external surface by the margin of the acetabulum. ... Gluteal lines can refer to: Inferior gluteal line Anterior gluteal line Posterior gluteal line Category: ... The greater sciatic foramen is bounded, in front and above, by the posterior border of the hip bone; behind, by the sacrotuberous ligament; and below, by the sacrospinous ligament. ...


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. Bones of the Hip In anatomy, the hip is the bony projection of the femur, known as the greater trochanter, and the overlying muscle and fat. ... In anatomy, the hip is the bony projection of the femur which is known as the greater trochanter, and the overlying muscle and fat. ...


Relations

A bursa is interposed between the tendon and the greater trochanter. Bursae visible top right and bottom right A bursa (plural bursae or bursas; Latin: Bursa synovialis) is a small fluid-filled sac located at the point where a muscle or tendon slides across bone. ... A tendon (or sinew) is a tough band of fibrous connective tissue that connects muscle to bone and is built to withstand tension. ...


Between the gluteus medius and gluteus minimus are the deep branches of the superior gluteal vessels and the superior gluteal nerve. The gluteus maximus is the largest of the gluteus muscles which are located in the buttock. ... The superior gluteal nerve is a nerve that originates in the pelvis which supplies the gluteus medius, the gluteus minimus, and the tensor fasciae latae muscles. ...


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. The Rectus femoris muscle is a muscle of the human body. ...


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. The tensor fasciae latae is a muscle of the thigh. ...


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 piriformis (from Latin piriformis = pear shaped) is a muscle in the gluteal region of the lower limb. ... The superior gemellus muscle is a muscle of the human body. ... The Vastus lateralis muscle is a muscle of the human body. ...

The gluteus minimus is covered by the last muscle, and passes from the ilium to the front of the great trochanter, thus rotating the hip joint inward.
The deep set is formed by three muscles which rise from the posterior surfaces of the tibia and fibula, the flexor longus digitorum, the tibialis posticus, and the flexor longus hallucis from within outward.
The deeper parts of the lateral mass of muscles spread to the ventral surface of the bodies of the vertebrae, and form the hypaxial muscles--such as the psoas, longus colli and recti capitis antics.
