The intergluteal cleft or just gluteal cleft, also known by a number of synonyms, including natal cleft and cluneal cleft, is the groove between the buttocks that runs from just below the sacrum to the perineum, [1] so named because it forms the visible border between the external rounded protrusions of the gluteus maximus muscles.
The gluteal sulcus (also known as the gluteal fold, tuck, fold of the buttock,, horizontal gluteal crease, or gluteal furrow) is an area of the body of humans and anthropoid apes, described by a horizontal crease formed by the inferior aspect of the buttocks and the posterior upper thigh. [1]
The masses of the gluteus maximus muscle are separated by an intermediate intergluteal cleft or "crack" in which the anus is situated. The buttocks allow primates to sit upright without resting their weight on their feet as four-legged animals do. Females of certain species of baboon have red buttocks that blush to attract males.
In particular, a pilonidal cyst in the gluteal cleft can resemble a sacrococcygeal teratoma. Correct diagnosis is important because all teratomas require consultation with an oncologist and complete surgical excision, if possible without any spillage.
Atypical dimples, on the other hand, have different characteristics. They are larger than 5 mm in size and are located within 25 mm of the anus. Atypical dimples can also be deep, positioned above the gluteal crease, located outside the midline, or occur as multiple dimples. [8]
Buttock cleavage is minor exposure of the buttocks and the intergluteal cleft between them, often because of low-rise pants. The crena is a formal term for the cleft between the buttocks. History
The dimples of Venus (also known as back dimples, Duffy Dimples, butt dimples or Veneral dimples) are sagittally symmetrical indentations sometimes visible on the human lower back, just superior to the gluteal cleft. They are directly superficial to the two sacroiliac joints, the sites where the sacrum attaches to the ilium of the pelvis. An ...
In humans, the anus (pl.: anuses or ani; from Latin ānus, "ring", "circle") [1] [2] is the external opening of the rectum located inside the intergluteal cleft.Two sphincters control the exit of feces from the body during an act of defecation, which is the primary function of the anus.
