The gluteus maximus' (or glutæus maximus) is the largest and most Superficial of the three Gluteal muscles. The gluteus medius (or glutæus medius) one of the three Gluteal muscles, is a broad thick radiating muscle situated on the outer surface of the Pelvis "Adipose" redirects here For the Doctor Who monster see " Partners in Crime " The superior aspect of the buttock ends at the iliac crest, and the lower aspect is outlined by the horizontal gluteal crease. The crest of the ilium (or iliac crest) is the superior border of the Wing of ilium and the superolateral margin of the Greater pelvis. The gluteal sulcus (also known as the gluteal fold or horizontal gluteal crease) is an area of the body of Great apes including humans described by a horizontal The gluteus maximus has two insertion points: 1/3 superior portion of the linea aspera of the femur, and the superior portion of the iliotibial tractus. The linea aspera is a ridge of roughened surface on the posterior aspect of the Femur, to which are attached Muscles and intermuscular Septa. The femur is the thigh bone In Humans, it is the longest, most voluminous and strongest Bone. The masses of the gluteus maximus muscle are separated by an intermediate gluteal cleft or "crack" in which the anus is situated.
