Identify the vestibule of the vagina, the region between the two labia minora. The urethral orifice lies in the anterior part of the vestibule of the vagina. Posterior to the urethral orifice identify the opening to the vagina called the vaginal orifice. In women who have not had sexual intercourse, the opening of the vagina is incompletely closed by a fold of mucous membrane called the hymen. In sexually active women, the ragged edges of the hymen, called the hymenal caruncles, can be identified.

On the sides of the vaginal orifice, attempt to identify the small opening of the duct of the greater vestibular gland (of Bartholin).
