Systema Genitale Feminae

Prominent, hair-bearing folds of skin extending posteriorly from the mons pubis to unite posteriorly in the midline.

Two smaller, hairless folds of soft skin lying between the labia majora.
Their posterior ends unite to form the fourchette.
Anteriorly, they split to enclose the clitoris, forming an anterior prepuce and a posterior frenulum.

A smooth triangular area bounded laterally by the labia minora, with the clitoris at its apex and the fourchette at its base.

A pair of small mucus-secreting glands that lie under the posterior parts of the bulb of the vestibule and the labia majora.
Each gland drains its secretion into the vestibule by a small duct, opening into the groove between the hymen and the posterior part of the labium minus.
They secrete lubricating mucus during sexual intercourse.

Corresponds to the penis in the male, located at the apex of the vestibule.
Has a structure similar to the penis.
Root: Composed of three masses of erectile tissue:
- bulb of the vestibule.
- right and left crura
Body: Consists of two corpora cavernosa, covered by their ischiocavernosus muscles.
Corpus spongiosum: A small amount of erectile tissue leading from the vestibular bulbs to the glans.
Glans: A small mass of erectile tissue that caps the body of the clitoris, with numerous sensory endings.

Anterior parts supplied by the ilioinguinal nerves and the genital branch of the genitofemoral nerves.
Posterior parts supplied by branches of the perineal nerves and the posterior cutaneous nerves of the thigh.

A muscular tube extending upward and backward between the vulva and the uterus.
Approximately 3 inches (8 cm) long.
Cervix of the uterus pierces its anterior wall.
Upper half lies above the pelvic floor within the pelvis; lower half lies within the perineum.
Relations: Anteriorly, related to the bladder and urethra; posteriorly, related to the rectouterine pouch (pouch of Douglas), its middle third to the ampulla of the rectum, and the perineal body; laterally, related to the ureter and broad ligament.
Supports: Upper third—levatores ani muscles and transverse cervical, pubocervical, and sacrocervical ligaments; middle third—urogenital diaphragm; lower third—perineal body.

A hollow, pear-shaped organ with thick muscular walls.
Approximately 3 inches (8 cm) long, 2 inches (5 cm) wide, and 1 inch (2.5 cm) thick in the young nulliparous adult.
Divided into fundus, body, and cervix.
Cervix: The narrow part of the uterus, piercing the anterior wall of the vagina. Divided into supravaginal and vaginal parts.
Cavity: The cavity of the cervix is called the cervical canal, communicating with the body cavity through the internal os and with the vagina through the external os.
Relations: Anteriorly, related to the uterovesical pouch and the superior surface of the bladder; posteriorly, related to the rectouterine pouch (pouch of Douglas); laterally, related to the broad ligament, uterine artery and vein and the ureter.

Oval in shape, measuring approximately 1.5 by 0.75 inches (4 by 2 cm).
Attached to the back of the broad ligament by the mesovarium, the lateral wall of the pelvis by the suspensory ligament of the ovary, and the lateral margin of the uterus by the round ligament of the ovary.
Position: Usually lies against the lateral wall of the pelvis in a depression called the ovarian fossa, sometimes hanging down in the rectouterine pouch.
During pregnancy, the enlarging uterus pulls the ovary upward into the abdominal cavity; after childbirth, the ovary assumes a variable position in the pelvis.

Each tube is approximately 4 inches (10 cm) long.
Lies in the upper border of the broad ligament.
Divided into four parts:
- Infundibulum: The funnel-shaped lateral end projecting beyond the broad ligament and overlies the ovary. Free edge has finger-like processes called fimbriae.
- Ampulla: The widest part of the tube, lying just lateral to the uterus.
- Isthmus: The narrowest part of the tube, lying just lateral to the uterus.
- Intramural part: The segment that pierces the uterine wall.
