The vagina is a median musculoskeletal tube that superiorly inserts itself into the contour of the middle part of the cervix of the uterus and downwards through the urogenital diaphragm to open in the female pudendum, whose hole is called the vagina ostium.

It is the copulatory organ of women.

The vagina has two walls, one anterior and one posterior, which remain attached to most of its length, representing a virtual cavity.

Superiorly the vagina behaves like a cylindrical tube to surround the vaginal portion of the uterine cervix, and inferiorly it flattens transversely to coincide with the female pudendum.

Vagina Channel

The dome of the vagina is represented by a recess that surrounds the highest part of the vaginal portion of the cervix and is called the vagina fornix.

Because the uterus is usually in anteroversion, the anterior part of the vagina is short and the posterior is longer, resulting in the posterior region of the fornix going higher or deeper.

In a virgin woman, the vagina ostium is partially filled with a mucous diaphragm called the hymen.

Structurally the vagina consists of a fibrous tunic, which surrounds a muscular tunic (smooth muscle fibers) and is internally lined with a mucous tunic.

Every mucosal surface is transversely creased, which are known as vaginal folds.

Larger Vestibular Glands

They are two small formations (0.5 cm in diameter each) located on either side of the vaginal orifice, in contact with the posterior end of each side of the vestibular bulb. They are rounded or oval and partially overlapped posteriorly by the vestibule bulbs. They secrete a mucus-rich substance that moistens and lubricates the hall.
