Anatomy of the
Female Reproductive System
The female reproductive system is divided into external
and internal genitalia. It also includes supporting structures
and is closely associated with the urinary and digestive systems in the pelvic
cavity.
I. External
Genitalia (Vulva)
Also known as the vulva, these structures are visible
externally and protect internal organs.
- Mons
pubis
- Fatty
tissue over the pubic bone, covered with hair after puberty.
- Labia
majora
- Thick,
outer folds of skin; contain sweat and sebaceous glands.
- Labia
minora
- Thinner,
inner folds of skin; rich in blood vessels and nerves.
- Clitoris
- Erectile
tissue; main organ for female sexual pleasure.
- Vestibule
- Space
between the labia minora that includes:
- Urethral
opening (for urine)
- Vaginal
opening
- Openings
of Bartholin's glands (secrete mucus for lubrication)
- Perineum
- Area
between vaginal opening and anus; important during childbirth.
II. Internal
Reproductive Organs
1. Vagina
- Muscular,
elastic tube (~8–10 cm long)
- Extends
from the cervix to the vulva
- Functions:
- Receives
penis during intercourse
- Passageway
for menstrual blood and childbirth
2. Uterus
- Hollow,
muscular, pear-shaped organ
- Divided
into:
- Fundus
– top dome
- Body
– central portion
- Isthmus
– narrow region
- Cervix
– lower part opening into vagina
- Uterine
wall layers:
- Endometrium
– inner lining; sheds during menstruation
- Myometrium
– thick muscular middle layer
- Perimetrium
– outer serosal layer
3. Fallopian Tubes (Uterine Tubes or Oviducts)
- Paired
tubes (~10 cm long) connecting ovaries to uterus
- Parts:
- Fimbriae
– finger-like projections near ovary
- Infundibulum
– funnel-shaped opening
- Ampulla
– main site of fertilization
- Isthmus
– narrow part connecting to uterus
4. Ovaries
- Paired,
oval-shaped glands (~3 cm long)
- Located
on either side of uterus
- Functions:
- Oogenesis
– production of ova (eggs)
- Secretion
of estrogen, progesterone, inhibin
🔹 III. Supporting
Ligaments
The reproductive organs are held in place by several
ligaments:
- Broad
ligament – supports uterus, fallopian tubes, ovaries
- Ovarian
ligament – connects ovary to uterus
- Suspensory
ligament – contains blood vessels; attaches ovary to pelvic wall
- Round
ligament – extends from uterus to labia majora
- Uterosacral
ligament – connects uterus to sacrum
Nerve & Blood Supply
- Arterial
supply: Mainly from the internal iliac artery
- Uterine
artery
- Ovarian
artery (from abdominal aorta)
- Vaginal
artery
- Innervation:
Via pelvic plexus (autonomic) and pudendal nerve (somatic)
