What are the layers of uterus...?

The uterus is a hollow, muscular organ that is shaped like an inverted pear. It has 3 parts: 

• The fundus is the top of the uterus.
• The body is the main part of the uterus and includes the uterine cavity.
• The cervix is the lower, narrow part of the uterus.

The thick wall of the uterus has 3 layers:

The endometrium is the inner layer that lines the uterus. It is made up of glandular cells that make secretions.

The myometrium is the middle and thickest layer of the uterus wall. It is made up mostly of smooth muscle.

The perimetrium is the outer serous layer of the uterus. The serous layer secretes a lubricating fluid that helps to reduce friction. The perimetrium is also part of the peritoneum that covers some of the organs of the pelvis.
