The uterus is supplied by arterial blood both from the uterine artery and the ovarian artery. Another anastomotic branch may also supply the uterus from anastomosis of these two arteries.
Nerve supply
Afferent nerves supplying uterus are T11 and T12. Sympathtic supply is from hypogastric plexus[disambiguation needed] and ovarian plexus. Parasympathetic supply is from second, third and fourth sacral nerves.
Development
The bilateral Müllerian ducts form during early fetal life. In males, MIF secreted from the testes leads to their regression. In females these ducts give rise to the Fallopian tubes and the uterus. In humans the lower segments of the two ducts fuse to form a single uterus, however, in cases of uterine malformations this development may be disturbed. The different uterine forms in various mammals are due to various degrees of fusion of the two Müllerian ducts.
