Anatomy

Vulva

Question Answer
Blood supplyexternal and internal pudendal arteries
LymphMedial group of superficial inguinal nodes
Nerve supply(anterior)-Anterior parts of vulva: iIlioinguinal nerves and the genital branch of the genitofemoral nerves
Nerve supply(posterior)-Posterior parts: Perineal nerves and posterior cutaneous nerves of the thigh
memorize

Vagina

Question Answer
Primary blood supplyVaginal branch of the uterine artery
Secondary blood supplies.Middle rectal and inferior vaginal branches of the hypogastric artery
(internal iliac artery)
Nerve Supply -Hypogastric plexus= SNS innervation
- Pelvic nerve= PNS innervation
memorize

Uterus

Question Answer
The visceral layer of the peritoneum reflects against the
uterus and forms this outmost layer of the organ
Mesometrium
3 parts of the Myometrium1. Outer longitudinal
2. Middle oblique
3. Inner longitudinal
Blood Supply-Uterine arteries—arise from internal iliac artery
-Ovarian arteries
Nerve Supply-Hypogastric plexus(Sup and Infer)
-Common iliac nerves
memorize

Ligaments

Question Answer
Broad ligamentContains the fallopian (uterine) tube, round ligament, uterine and
ovarian blood vessels, lymph, utererovaginal nerves, and ureter
Round ligamentRemains of the gubernaculum
Cardinal ligamentExtends from the cervix and lateral vagina to the

memorize

Question Answer
4 parts?
 1)Infundibulum: The lateral most part the uterine tube. The free edge is connected to the fimbriae.
 2)Ampulla: Widest section
3) Isthmus: Narrowest part
4) Intramural part: Pierces uterine wall
Blood supplyUterine and ovarian arteries(same as uterus)
Nerve Supply1)Pelvic plexus (autonomic) and
2)ovarian plexus
arises from the renal plexus, and is distributed to the ovary, and fundus of the uterus.

It is carried in the suspensory ligament of the ovary
memorize

Ovaries

Question Answer
LocationPosterior aspect of the broad ligament, and are attached
to the broad ligament by the mesovarium.

-They are NOTcovered by peritoneum.
Blood Supply-Ovarian artery, which arises from the aorta at the level of L1.

-Veins drain into the vena cava on the right side and the left renal vein on the left.
Nerve SupplyDerived from the Aortic plexus
Histo-Covered by tunica albuginea, a fibrous capsule.
-The tunica albuginea is covered by germinal epithelium.
