Anatomy of the Fallopian tube and Ovaries and Vagina Dr. Mohammed Alshamiri Consultant of Urology Fallopian tube  Fallopian tube The Fallopian tube is one on each side. Each tube is about 10 cm long. Each tube has medial (uterine) end and lateral (ovarian) end.  1.fallopian tube Parts of Interstitia l part 2. lsthmus 3. Ampulla 4. Infundibu lum  Functions it carries the ova from the ovary to the uterus.  Blood supply The medial part of the fallopian tube is supplied by tubal branches of the uterine artery, while its lateral part is supplied by the ovarian artery.  Lymphatic Drainage Into the pre- aortic and para- aortic lymph nodes.  Applied.Anatomy Pregnancy in the fallopian tube is called ectopic  Ovaries Site Size and Shape  Site, shape and size it lies in the "ovarian fossa" on the side wall of the pelvic wall between the internal and external iliac arteries. Ovoid in shape 3 X 2 X I cm (Almond shape).  Functions 1. It produces ova. 2. It secretes female sex hormones ( estrogen progesteron e). Relations  Relations 1. Ends: (ligaments) a. Uterine end: Attactied to the lateral angle of the uterus by the ovarian ligament b. Tubal end. attached to: - ovarian fimbria of the fallopian tube. Suspensory ligament of the ovary  Surface 1-Lateral surface It is covered by the peritoneum. It lies in the ovarian fossa. It is related to the obturator nerve and vessels in the floor of fossa. 2- medial surface - it is related to the fimbria of the Borders a. Attatched (anterior) border:- It gives attachment to the mesovarium. It has the 'hilum- which receives the ovarian blood vessels. b, Free (posterior) border:- Directed  Applied Anatomy The close relation of the lateral surface of the ovary to the obturator nerve in the ovarian fosse, explains the pain which is felt along the cutaneous distribution of the obturator nerve (on Relations of ovaries  Ligaments 1.

Ovarian ligaments Blood supply  Blood supply 1. ovarian artery: it enters through the suspensory ligament of the ovary then through tho mesovarium to reach the ovary 2. Uterine artery: it anastomosis freely with the ovarian artery. Venous Drainage  Venous Drainage The veins draining the ovary form a pampiniform plexus. it gives rise to ovarian vein which accompanies ovarian artery. The right ovarian vein ends in IVC while the left one ends in left renal vein.  Lymphatic Drainage Into the para-aortic lymph nodes. Lymphatics also pass to the inguinal lymph nodes via the round ligament, and to the opposite ovary by passing across the fundus of the uterus. Lymphatic drainage  Vagina Stricture it is a canal which connects the uterus to the vestibule (outside).  Direction:- it is directed upwards and backwards. Length The anterior wall is about 3 inches. The posterior wall is 4 inches  Relations Anterior wall a. Base of the urinary bladder. b. Urethra. 2. Posterior wall:- Upper 1/3: Related to "peritoneum of the Douglas pouch. Middle 1/3: Related to "lower 1/3 of rcctum". c. Lower 1/3: Relatcd to "perineal Relations Lateral wall  Lateral wall a. Upper third (lateral fornix), related to: Uterin artery Ureter which is crossed superiorly from lateral to medial by the uterine artery. b. Middle third, relatcd to: - Levator ani c. Lower third, related to: - - Greater vestibular gland. Fornices of vagina  Blood supply 1. Vaginal artery 2. Uterine artery 3. Middle rectal artery 4. Internal pudendal artery.  Upper Lymphatic Drainage part drains to internal and external iliac LNs -Middle part drains to internal iliac LNs
