Anatomy of the Female Reproductive Tract (L3Wk1)

Describe the blood supply of the uterus.

Arteries: mainly from the uterine artery which is a branch of the internal iliac artery. Also anastomosing with the ovarian artery. A small descending branch supplies the cervix and vagina. Veins: the uterine vein follows the artery and drains into the internal iliac vein.

Describe the blood supply of the overaies.

Arteries: the ovarian artery arises from the abdominal aorta at the level of L1. Veins: the ovarian vein drains into the inferior vena cava on the right side and into the left renal vein on the left side.

Describe the blood supply of the uterine tubes.

Arteries: the uterine artery from the internal iliac artery and the ovarian artery from the abdominal aorta supply the uterine tube. Veins: correspond to arteries.

Describe the nerve supply of the uterus.

Sympathetic and parasympathetic nerves from branches of the inferior hypogastric plexuses innervate the uterus.

Describe the lymph drainage of the ovaries.

The lymph vessels of the ovary follow the ovarian artery and drain into the para-aortic nodes at the level of L1

Describe the nerve supply of the ovaries.

The nerve supply to the ovary is derived from the aortic plexus and accompanies the ovarian artery.

Describe the nerve supply of the uterine tubes.

sympathetic and parasympathetic nerves from the inferior hypogastric plexuses supply the uterine tube.

What is the lymphatic drainage of the uterus?

the lymph vessels from the fundus accompany the ovarian artery and drain into the para aortic nodes at the level of L1. The vessels from the body and cervix drain into the internal and external iliac lymph nodes.

Describe the lymph drainage of the vagina.

the lymph vessels from the upper third drain to the external and internal iliac nodes, from the middle third to the internal iliac nodes, and from the lower third to the superficial inguinal nodes.

Describe the lymph drainage of the uterine tubes.

the lymph vessels from the uterine tube follow the corresponding arteries and drain into the internal iliac and para-aortic nodes.

What nerves supply the vagina?

the nerve supply to the vagina is from the inferior hypo-gastric plexuses.

Describe the blood supply of the vagina.

the vaginal artery, a branch of the internal iliac artery, and the vaginal branch of the uterine artery. Veins: the vaginal veins form a pluxux around the vagina that drains into the internal iliac vein.
