Study Notes

External Female Structures

The external female reproductive organs are collectively called the Vulva
Mons Pubis: Rounded, soft fullness over the symphysis pubis covered with pubic hair
Labia Majora: Two fleshy folds extending from the mons pubis to the perineum, protecting the labia minora, urinary meatus, and vaginal introitus
Labia Minora: Narrow folds located between the labia majora, pigmented, similar to vaginal mucosa
Clitoris: Erectile organ highly sensitive to temperature, touch, and pressure
Vestibule: Oval-shaped area between the labia minora, clitoris, and fourchette, containing the external urethral meatus, vaginal introitus, and Bartholin's glands
Perineum: Posterior part of the external female reproductive organs extending from the fourchette to the anus, composed of fibrous and muscular tissues supporting pelvic structures

Internal Female Structures

Vagina: Elastic fibro-muscular tube connecting the uterus to the vestibule
Uterus: Hollow, pear-shaped muscular organ measuring 7.5 X 5 X 2.5 cm, normally anteverted and antiflexed
Fallopian Tubes: Two tubes extending from the cornu of the uterus to the ovary, divided into:
- Interstitial part: Runs into the uterine cavity, between the fundus and body of the uterus, 1-2 cm long
- Isthmus: Narrow part adjacent to the uterus, 2-3 cm long
- Ampulla: Wider part, 5 cm long, where fertilization occurs
- Infundibulum: Funnel-shaped part with fimbriae (fingerlike processes) that help with ovum pickup
Ovaries: Oval solid structures located on each side of the uterus, producing estrogen & progesterone and ova

Structure of the Ovaries

Cortex: Outer layer
Medulla: Inner layer
Hilum: Area where blood vessels and nerves enter

Function of the Uterus

Menstruation: Uterus sloughs off the endometrium
Pregnancy: Uterus supports and allows fetus to grow
Labor and Birth: Uterine muscles contract and cervix dilates to expel fetus

Function of the Vagina

Allows discharge of menstrual flow
Serves as female organ for intercourse
Allows passage of the fetus from the uterus

Layers of the Uterus

Perimetrium: Outer peritoneal layer
Myometrium: Middle thick muscle layer with longitudinal, figure-8, and circular fibers
Endometrium: Inner layer responsive to estrogen and progesterone, consisting of the compact, basal, and functional layers

Support Structures

Bony Pelvis: Supports and protects the lower abdominal and internal reproductive organs
