Study Notes
L39 - Reproductive System - Female
- The female reproductive system is located in the pelvic cavity and perineum.
- During pregnancy, it extends into the abdomen.
- Learning Outcomes include: gross anatomy of ovary, Fallopian tube, and uterus.
- Applied anatomy (anatomical basis) of common clinical conditions.
- Gross anatomy of Vagina & external genitalia.
- Anatomy of mammary gland.
- Applied anatomy (anatomical basis) of common clinical conditions.
Ovaries
- Ovaries are female gonads.
- Oocytes are formed in ovaries.
- Ovaries are located in the ovarian fossa on the lateral pelvic wall.
- In young girls, before ovulation, ovaries have smooth greyish pink surfaces.
- After puberty, ovarian surfaces become uneven and greyish.
- Each ovary has two poles (upper/tubal pole, lower/uterine pole).
- Two borders (anterior/mesovarian, posterior/free).
- Two surfaces (lateral and medial).
- Arterial supply is from the abdominal aorta (ovarian artery).
- Venous drainage emerges at the hilus, forming a pampiniform plexus around the artery.
- Lymphatic drainage is to lateral and pre-aortic nodes.
- Nerve supply includes sympathetic nerves (T10, T11) which are afferent for pain and vasomotor. Parasympathetic nerves (S2, S3, S4) are vasodilator.
- Functions include the production of oocytes and hormones (estrogen and progesterone).
- Applied conditions include ovarian prolapse (displacement to pouch of Douglas) and ovarian cysts (developmental arrest of follicles).
Uterine Tubes
- Also called Fallopian tubes
- A pair of tortuous ducts that carry ova to the uterine cavity.
- 10 cm in length.
- Situated in the upper free margin of the broad ligament of the uterus.
- Transport of ova into uterine tubes is facilitated by longitudinal grooves on the ovarian fimbria, ciliary beats, and peristalsis of tubal musculature.
- Two openings (uterine ostium and pelvic/abdominal ostium).
- Four parts: (a) Pars uterina tubae (intra-mural part), (b) Isthmus, (c) Ampulla, and (d) Infundibulum.
- Blood supply from ovarian and uterine arteries and veins.
- Nerve supply from sympathetic nerves (T10 to L2), parasympathetic (lateral part of tube from vagus, medial part from pelvic splanchnic nerves).
- Applied conditions include tubal pregnancy (ectopic pregnancy), pyosalpinx (pus-filled tube), salpingitis (inflammation), sterility (tubal blockage).
Uterus
- Pear-shaped, hollow, muscular organ.
- Located within the true pelvis and between the bladder and rectum.
- Covered with peritoneum except anteriorly.
- Consists of two parts (a) body (corpus uteri - upper 2/3), (b) cervix (lower 1/3).
- Positions include anteflexion (long axis of body bent forward), anteversion (long axis of cervix bent forward), retroverted (fundus and body of uterus bent backward), and retroflexed (body bent backward on cervix).
Perineal Body
- Fibromuscular structure in the perineum between the vagina and anal canal.
- Maintains integrity of the pelvic floor.
- Damage during childbirth may lead to prolapse of pelvic viscera.
Vagina
- Female organ of copulation.
- Forms lower part of birth canal.
- Extends from vestibule to vaginal part of cervix.
- Upward and backward position at 45° to uterus.
- Anterior wall - 8 cm; Posterior wall - 10 cm.
- Lumen resembles an "H" in the lower third, a transverse slit in the middle third, and a rounded shape in the upper third.
External Female Genitalia
- Mons pubis: fatty eminence over pubic symphysis.
- Labia majora: two longitudinal folds of skin enclosing the pudendal cleft (outer surface is pigmented and hairy, inner is smooth and contains sebaceous glands).
- Labia minora: two small folds between the labia majora, enclosing the vestibule. Vestibule has vaginal orifices, ducts of vestibular glands, and urethra.
- Clitoris: homologous to male penis (corpora cavernosa, glans, but no corpus spongiosum). Erectile tissue, highly sensitive.
- Bulbs of vestibule: two masses of erectile tissue on either side of the vaginal orifice.
- Vestibular glands of Bartholin: lie near the vaginal orifice. Their ducts open between the hymen and labia minora.
- Hymen: membrane partially covering the vaginal orifice in virgins. Not a reliable indicator of virginity.
- Applied anatomy includes per vaginal examination, vaginal smears (diagnostic test for vaginal discharge), cysts of vestibular glands, imperforate hymen, dyspareunia (painful intercourse), and episiotomy.
Mammary Gland
- Modified sweat gland
- Derived from skin epithelium.
- Rudimentary in males, well developed in females after puberty.
- Located in superficial fascia of anterior chest wall (2nd rib to 6th rib, along mid-clavicular line, extends to mid-axillary line).
- Variable size, extending into axillary tail of Spence
- Nipple: conical elevation.
- Areola: pigmented area around nipple, has modified sebaceous glands and Montgomery tubercles.
- Cooper ligaments: connective tissue anchoring breast to dermis.
- 15-20 lobes separated by fibrous connective tissue.
- Each lobe is drained by lactferous ducts (converging near nipple, with a dilated lactiferous sinus).
- Applied Anatomy includes peau d'orange (orange peel skin), advanced breast carcinoma (tumors that grow through retro-mammary space, fix to chest wall, shorten suspensory ligaments), and mastia, absence of breast/nipple).
- Additional applied anatomy includes gynecomastia (condition of benign breast growth in males frequently during adolescence).
Lymphatic Drainage of Breast
- Drainage to axillary, internal thoracic and para-aortic nodes.
- Superficial & deep drainage routes; important clinically
