Intergluteal cleft

Intergluteal cleft also known as the natal cleft or butt crack is a deep groove located posteriorly on the human body, between the buttocks, that runs from just below the sacrum to the perineum.

Etymology

The term "intergluteal" is derived from the Latin words "inter" meaning "between" and "gluteus" meaning "buttock". The term "natal cleft" is derived from the Latin word "natis" meaning "buttock" and the English word "cleft" meaning "split".

Anatomy

The intergluteal cleft is located between the two gluteus maximus muscles, which are the largest muscles in the human body. These muscles are responsible for the movement of the hip and thigh. The cleft is lined with skin and hair, and its depth and length can vary greatly from person to person.

Clinical significance

The intergluteal cleft can be the site of several health issues. Pilonidal disease, a chronic skin infection in the crease of the buttocks near the coccyx, often occurs in the intergluteal cleft. Pruritus ani, or itching of the skin around the anus, can also affect this area.

Cultural significance

In many cultures, the intergluteal cleft is considered a private part of the body and is usually covered by clothing in public settings. However, in some cultures and contexts, it is considered acceptable or fashionable to display part of the intergluteal cleft.
