Question 4

What is the lymphatic drainage of the left ovary?

Answer 4

Para-aortic nodes.

Question 5

What is the venous drainage of the uterus?

Answer 5

Uterine venous plexus and the Internal Iliac Veins.

Question 6

What is the lymphatic drainage of the uterus?

Answer 6

Fundus: Para-aortic/Superficial Inguinal nodes.
Body: External Iliac Node.

Question 7

What is the venous drainage of the cervix?

Answer 7

Uterine venous plexus, Internal Iliac Veins.

Question 8

What is the lymphatic drainage of the cervix?

Answer 8

Internal Iliac/Sacral Nodes.

Question 9

What is the venous drainage of the vagina?

Answer 9

Vaginal venous plexus (meets uterine plexus to form uterovaginal plexus).

Question 10

What is the lymphatic drainage of the vagina?

Answer 10

Superior: Internal and External Iliac Nodes.
Middle: Internal Iliac Nodes.

Question 11

What is the innervation of the vulva?

Answer 11

Receives sensory and parasympathetic nervous supply.
Anterior: Ilioinguinal Nerve and Genital Branch of the Genitofemoral Nerve.
Posterior: Pudendal Nerve and Posterior Cutaneous Nerve of the Thigh.
Clitoris and the vestibule: parasympathetic innervation from the cavernous nerves from uterovaginal plexus.

Question 12

What is the arterial supply of the uterus?

Answer 12

Uterine artery.

Question 13

What is the Artery Supply of the ovaries?

Answer 13

Ovarian Artery.

Question 14

What is the arterial supply of the vagina?

Answer 14

Vaginal arteries and uterine arteries formed by the Internal Iliac Arteries.

Question 15

What is the Innervation of the Uterus?

Answer 15

Uterovaginal plexus. Parasympathetic fibres of the uterus are derived from the pelvic splanchnic nerves.

Question 16

What is the Innervation of the Cervix?

Answer 16

Inferior nerve fibres of the uterovaginal plexus. Afferent fibres mostly ascend through inferior hypogastric plexus to enter the spinal cord via T10-T12 and L1 nerve fibres.

Question 17

Describe the Broad Ligament.

Answer 17

A flat sheet of peritoneum associated with the uterus, Fallopian tubes and ovaries. Extends from the lateral pelvic walls on both sides and folds over the internal female genitalia, covering their surface anteriorly and posteriorly.
Mesometrium: surrounds the uterus and is the largest subsection. Covers the External Iliac Vessels. Encloses part of the round ligament.
Mesovarium: associated with the ovaries. Projects from the posterior surface of the broad ligament and attaches to the hilum of the ovary, enclosing the neuromuscular supply.
Mesosalpinx: originates superiorly to the mesovarium, enclosing the fallopian rube.

Question 18

Describe the Ovarian Ligament.

Answer 18

Associated with the ovary inferiorly, connecting the the ovary to the side of the uterus. Remnant of the gubernaculum.

Question 19

Describe the Suspensory Ligament of the Ovary.

Answer 19

Outward from the ovary to the lateral abdominal wall. Consists of a fold of peritoneum. Contains the ovarian nerves and vessels.

Question 20

Describe the Round Ligament.

Answer 20

Remnant of the embryonic gubernaculum. Originates at the uterus horns and attaches to the labia major, passing through the inguinal canal.

Question 21

What do PEG cells do?

Answer 21

Release nutrients and important factors for the egg and sperm.
