Layers:- The uterus has three layers, of which the middle
muscle layer is by far the thickest.
The endometrium: - forms a lining of ciliated epithelium
(mucous memberane) on a base of connective tissue or
stroma. It is constantly changing in thickness through out the
menustral cycle.
The myomatrium or muscle coat: - is thick in the upper part
of the uterus and is sparser in the isthmus and cervix. It has
three parts: Outer longitudinal, middle oblique and inner
circular.
The perimetrium is a double serous memberane, an
extension of the peritoneum, which is dragged over the
uterus.
Blood supply – The uterine artery arrives at the level of the
cervix and is a branch of the internal iliac artery. The blood
drains through corresponding veins.
Nerve supply – from the autonomic nervous system,
sympathetic and para smpathetic via pelvic plexus.
