By its dictionary and anatomical definitions, however, vagina refers exclusively to the specific internal structure, and understanding the distinction can improve knowledge of the female genitalia and aid in health care communication.Although by its dictionary and anatomical definitions, the term vagina refers exclusively to the specific internal structure, it is colloquially used to refer to the vulva or to both the vagina and vulva.In mammals, the vagina is the fibromuscular, tubular part of the female genital tract extending, in humans, from the vulva to the cervix.The outer vaginal opening is normally partly covered by a membrane called the hymen.Where the vaginal lumen surrounds the cervix of the uterus, it is divided into four continuous regions or vaginal fornices; these are the anterior, posterior, right lateral, and left lateral fornices.
It is supported by the upper portions of the cardinal ligaments and the parametrium.
This is different from male mammals, who usually have a single urethral opening for both urination and reproduction.
The vaginal opening is much larger than the nearby urethral opening, and both are protected by the labia in humans.
Otherwise, being very elastic, it may return to its normal position.
Additionally, the hymen may be lacerated by disease, injury, medical examination, masturbation or physical exercise.
At the deep end, the cervix (neck of the uterus) bulges into the vagina.
