Vulva is supplied by which artery?
Correct Answer: All of the above
Description: Ans. d (All of the above). (Ref. Dutta, Anatomy, Thorax and Abdomen, 2nd/pg.309)# Branches of internal pudendal artery, including transverse labial perineal artery, artery to vestibular bulb and deep and dorsal artery to clitoris, chiefly supply vulva.# The vaginal artery corresponds to inferior vesical artery in males and supplies the vagina, bulb of vestibule.# Vaginal artery is branch of internal illiac artery, which supplies valva.BLOOD SUPPLY OF THE GENITAL TRACT# The blood supply to the genital organs comes from the ovarian arteries and uterine and vaginal branches of the internal iliac arteries.# The blood supply of the upper adnexal structures comes from the ovarian arteries that arise from the anterior surface of the aorta just below the level of the renal arteries.# The accompanying plexus of veins drains into the vena cava on the right and the renal vein on the left. Ovarian artery not only supplies the gonad but also sends small vessels through mesosalpinx to supply the fallopian tube, including a prominent fimbrial branch at the lateral end of the tube.# The uterine artery originates from the internal iliac artery. It usually arises independently from this source but can have a common origin with either the internal pudendal or vaginal artery. Accompanying each uterine artery are several large uterine veins that drain the corpus and cervix.# The vagina receives its blood supply from a downward extension of the uterine artery along the lateral sulci of the vagina and from a vaginal branch of the internal iliac artery. These form an anastomotic arcade along the lateral aspect of the vagina at the 3- and 9-o'clock positions. The distal vagina also receives a supply from the pudendal vessels, and the posterior wall has a contribution from the middle and inferior hemorrhoidal vessels.LYMPHATICS OF THE GENITAL TRACT# Lymphatic drainage of the upper two thirds of the vagina and uterus is primarily to the obturator and internal and external iliac nodes, and the distal-most vagina drains with the vulvar lymphatics to the inguinal nodes. In addition, some lymphatic channels from the uterine corpus extend along the round ligament to the superficial inguinal nodes, and some nodes extend posteriorly along the uterosacral ligaments to the lateral sacral nodes.# The lymphatic drainage of the ovary follows the ovarian vessels to the region of the lower abdominal aorta, where they drain into the lumbar chain of nodes (paraaortic nodes).NERVE SUPPLY:# The uterus receives its from the uterovaginal plexus (FrankenhAuser ganglion) that lies in the connective tissue of the cardinal ligament..
