Perimetrium

The Perimetrium (/pɛrɪˈmiːtrɪəm/; from Greek 'peri-', meaning "around" or "surrounding", and 'metra', meaning "womb") is the outermost layer of the uterus. It is a part of the female reproductive system and plays a crucial role in the process of menstruation and pregnancy.

Etymology

The term 'Perimetrium' is derived from the Greek words 'peri-', which means "around" or "surrounding", and 'metra', which means "womb". This is reflective of the perimetrium's role as the outermost layer surrounding the uterus.

Anatomy

The perimetrium is a serous layer of visceral peritoneum. It covers the outer surface of the uterus and extends to the lateral parts of the organ. The perimetrium is contiguous with the mesometrium, which is part of the broad ligament of the uterus.

Function

The primary function of the perimetrium is to protect and support the uterus within the pelvic cavity. It also aids in the lubrication of the uterus, reducing friction from the movements of the uterus during pregnancy and menstruation.
