Female reproductive organ which assists in carrying the egg from the ovary to the uterus. It is divided into four part

bullet Uterotubal junction or junctura
bullet Isthmus
bullet Ampulla
bullet Infundibulum or preampulla

Arteries

bullet

Uterine artery from the internal iliac artery

bullet

Ovarian artery from the abdominal aorta. The two anastomose at the mesosalpinx (see below). The uterine artery have a unique away of supplying the whole of the uterus. Firstly they divide into anterior and posterior arcuate arteries at the uterine walls. Then they pass transversely across the uterine tissue anastomosing with each other (left and right vessels). They provide radial branches which pass into the myometrial layers and then give the spiral or helicine arterioles, which supply the endometrium. These helicine arterioles are important in the process of menstruation.

Veins

bullet

Uterine veins drain into the internal iliac vein.

bullet

Ovarian veins drain into the inferior vena cava on the right) and left renal vein on the left. The two veins anastomose at the mesosalpinx. There is a longitudinal anastomoses from the ovarian veins or ovarian artery superiorly at the level of the ovary to the azygos artery or vein of the vagina below, which is a tributary (or branch) of internal pudendal vein. The vessels, which take part in this anastomoses are as follows

Vaginal veins

Middle rectal veins

bullet

Azygos veins of the vagina

Nerves: Uterine nerves

bullet

Branches of the inferior hypogastric plexus

bullet

Motor fibers are poorly understood. Vasoconstrictor nerves are sympathetic and probably motor to uterine musculature.

bullet

Sensory fibers are from the paraysympathetic and sympathetic systems.
