Female Pelvic Anatomy Quiz

Study Notes

Approximately 1 1/2 inches (3.8 cm) long
Extends from the neck of the bladder to the external meatus
Opens into the vestibule about 1 inch (2.5 cm) below the clitoris
Traverses the sphincter urethrae and lies in front of the vagina
Small openings of the ducts of the paraurethral glands are located at the sides of the external urethral meatus

A pair of small mucus-secreting glands
Located under the posterior parts of the bulb of the vestibule and the labia majora
Each drains its secretion into the vestibule by a small duct
Ducts open into the groove between the hymen and the posterior part of the labium minus

Extends upward and backward between the vulva and the uterus
Approximately 3 inches (8 cm) long
Cervix of the uterus pierces its anterior wall
Vaginal orifice in a virgin possesses a thin mucosal fold called the hymen
Upper half of the vagina lies within the pelvis, lower half lies within the perineum
Supports: upper third (levatores ani muscles, transverse cervical, pubocervical, and sacrocervical ligaments), middle third (urogenital diaphragm), lower third (perineal body)
Blood supply: vaginal artery (branch of internal iliac artery) and vaginal branch of uterine artery
Veins: vaginal veins drain into internal iliac veins
Lymph drainage: upper third (internal and external iliac nodes), middle third (internal iliac nodes), lower third (superficial inguinal nodes)
Nerve supply: nerves from inferior hypogastric plexuses

Collective name for the female external genitalia
Includes mons pubis, labia majora and minora, clitoris, vestibule of vagina, vestibular bulb, and greater vestibular glands
Lymph drainage: skin of vulva is drained into medial group of superficial inguinal nodes
Nerve supply: anterior parts (ilioinguinal nerves and genital branch of genitofemoral nerves), posterior parts (branches of perineal nerves and posterior cutaneous nerves of the thigh)
Blood supply: branches of external and internal pudendal arteries on each side
