The muscle is thick, two layers of beams are distinguished in it - superficial and deep. Muscular bundles are arranged fan-shaped, beginning with a wide part from the outer surface of the wing of the ilium , bordered from the front by the anterior gluteal line, from above by the iliac crest, from below by the back gluteal line. Then all the muscle bundles converge into a common, powerful tendon that attaches to the top and outer surface of the large trochanter, where there are more often two, rarely three vertebral bags of the middle gluteus muscle, bursae trochantericae m. Glutei medii.

Function: pulls the hip , with the front beams rotate the thigh inward, and the rear beams outward; Participates in the straightening of the bent forward torso.
