== Vestibule ==
* Extends from the external urethral opening to the external vulva, so combines urinary and reproductive functions.
* Shorter than the vagina.
* Lies mostly behind the ischial arch, sloping ventrally to its opening at the vulva.
* The wall contains vestibular glands.
** Secretions from these glands keeps the mucosa of the vestibule moist and facilitates coitus and parturition.
** At oestrus, the odour of these secretions sexually stimulates the male.
