Identify parts of the body mentioned and make it into a numbered list. 

Anatomically, the mass of each buttock principally comprises two muscles—the gluteus maximus muscle and the gluteus medius muscle—which are covered by a layer of adipose body fat. The upper aspects of the buttocks end at the iliac crest (the upper edges of the wings of the ilium, and the upper lateral margins of the greater pelvis), and the lower aspects of the buttocks end at the horizontal gluteal crease, where the buttocks anatomy joins the rear, upper portion of the thighs. The gluteus maximus muscle has two points of insertion: (i) the one-third superior portion of the (coarse line) linea aspera of the thigh bone (femur), and (ii) the superior portion of the iliotibial tract (a long, fibrous reinforcement of the deep fascia lata of the thigh). The left and the right gluteus maximus muscles (the butt cheeks) are vertically divided by the intergluteal cleft (the butt-crack) which contains the anus.[1]

The gluteus maximus muscle is a large and very thick muscle (6–7 cm) located on the sacrum, which is the large, triangular bone located at the base of the vertebral column, and at the upper- and back-part of the pelvic cavity, where it is inserted (like a wedge) between the two hip bones. The upper part of the sacrum is connected to the final lumbar vertebra (L5), and to the bottom of the coccyx (tailbone). At its origin, the gluteus maximus muscle extends to include parts of the iliac bone, the sacrum, the coccyx, the sacrosciatic ligament, and the tuberosity of the ischium.[2]

Like every pelvic-area muscle, the gluteus maximus muscle originates from the pelvis; nonetheless, it is the sole pelvic muscle not inserted to the trochanter (head of the femur), and is approximately aligned to the femur and the fascia lata (the deep fascia of the thigh); the tissues of the gluteus maximus muscle cover only the rear, lateral face of the trochanter, and there form a bursa (purse) that faces the interior of the thigh.[3]
