**Sciatic Foramen Lesser**

The sciatic foramen is an anatomical formation that is a small gap between the pelvic bones and is part of the ischiocavernosal arch. It serves to pass nerve endings, blood vessels and muscles through the pelvis during the transition from the thigh to the buttock. This hole is important for human health, since disruption of its function can lead to various diseases and complications. In this article we will look at the features of the lesser sciatic foramen, its structure and functions, as well as possible diseases and pathologies associated with this opening.

Features of the lesser sciatic foramen The lesser sciatic foramen is one of three sciatic foramina that are located in the small pelvis. If we take the diagram of the structure of the small pelvis, then the sciatic openings will be located in the center of the inner surface of the pelvic diaphragm. It connects the two bones of the small pelvis - the sacrum and the pubis. At the same time, the line of the ischium in women is higher than in men. The small ischium is usually located at the level of the second or third sacral vertebrae.

**Sciatic foramen, minor (foramen** ischiadicus _minor)_ is a wide and deep opening that is located between the superior posterior iliac spine and the sacrotuberous ligament of the sacral spine, connecting the pelvic cavity and the infrapiriform foramen. It is formed during the development of the fetus in the 5-6th week of pregnancy. Normally, it closes completely by the 8th month of pregnancy. In women, it forms in two stages of formation: first, by the 25th week of pregnancy, it is very narrow, and then it expands until the 35th week of pregnancy; sometimes a false small sciatic foramen (partial
