Ischioanal fossa
The ischioanal fossa , also known as the infralevatoric space, is a space in the posterior region of the perineum filled with fatty tissue (Liebl'scher fat body) . Its lateral wall contains the pudendal canal (also called Alcock canal ) as an important structure for supplying the perineum and the external genitalia .
Limitations
After cranial fossa ischioanalis is the levator ani limited. It is connected to the subperitoneal connective tissue space of the pelvis through the levator gate released by this . In the caudal direction , the fossa is partially covered by the deep transversus perinei muscle , but the posterior area in particular merges into the subcutaneous fatty tissue without separation .
The lateral boundaries are also formed by the levator ani muscle towards the middle of the body , the internal obturator muscle and the ischii muscle towards the side .
