The '''gluteus minimus''', the smallest of the three [[gluteal muscles]], is situated immediately beneath the [[gluteus medius]].
==Origin and insertion==
[[Image:Gluteus minimus muscle.PNG|thumb|left|Muscles of the gluteal and posterior femoral regions with gluteus minimus muscle highlighted.]]
It is fan-shaped, arising from the outer surface of the [[Ilium (bone)|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 (anatomy)|hip joint]].
==Relations==
A [[bursa (anatomy)|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".
