The vagina is an organ of the female reproductive tract. It is a distensible muscular tube which extends posterosuperiorly from the external vaginal orifice to the cervix. In this article, we will look at the anatomy of the vagina — its structure, innervation, vascular and lymphatic supply. Fig 2 — Sagittal section of the female pelvis, showing the anatomical relations of the vagina. The vagina is a fibromuscular tube with anterior and posterior walls — these are normally collapsed and thus in contact with one another. The shape of the vagina is not a round tunnel.

Clinical anatomy is concerned with the anatomic relationships between various structures of the living human organism. These relationships in the pelvis and their physiologic alterations along with the degree of independent function of each organ system are the concern of the gynecologist. Pelvic anatomy is complex and requires careful study and cadaveric dissection. A three-dimensional understanding of the interplay between bones, ligaments, pelvic organs, and muscles helps the gynecologist and pelvic surgeon identify and treat disorders of the pelvic floor.
Vagina , canal in female mammals that receives the male reproductive cells, or sperm , and is part of the birth canal during the birth process. In humans, it also functions as an excretory canal for the products of menstruation. In humans the vagina is about 9 cm 3. The upper region of the vagina connects to the cervix of the uterus. The vaginal channel is narrowest at the upper and lower ends.
A posterior vaginal prolapse, also known as a rectocele, occurs when the wall of fibrous tissue that separates the rectum from the vagina weakens. When this happens, tissues or structures just behind the vaginal wall — in this case, the rectum — can bulge into the vagina. A posterior vaginal prolapse occurs when the thin wall of tissue that separates the rectum from the vagina weakens, allowing the vaginal wall to bulge. Posterior vaginal prolapse is also called a rectocele REK-toe-seel. Childbirth and other processes that put pressure on pelvic tissues can lead to posterior vaginal prolapse.
