The inner buttocks, specifically the groove between them, is called the intergluteal cleft (or gluteal cleft). This is the groove that separates the rounded protrusions of the gluteus maximus.
According to the provided reference, the intergluteal cleft, also known by synonyms such as natal cleft and cluneal cleft, is the groove between the buttocks. It runs from just below the sacrum down to the perineum.
Here's a more detailed breakdown:
Anatomy of the Intergluteal Cleft
- Location: The cleft is situated between the left and right gluteus maximus muscles (the main muscles forming the buttocks).
- Extent: It spans from just below the sacrum (the triangular bone at the base of the spine) to the perineum (the area between the anus and the genitals).
- Synonyms: Common alternative names include natal cleft and cluneal cleft.
