Ovarian medulla

Ovarian Medulla

The Ovarian medulla is the innermost layer of the ovary, a female reproductive organ. It is surrounded by the ovarian cortex, which contains the ovarian follicles. The ovarian medulla is primarily composed of loose connective tissue and contains blood vessels, lymph vessels, and nerves.

Structure

The ovarian medulla is located beneath the ovarian cortex and is separated from it by the tunica albuginea. It is made up of stromal cells and is highly vascularized, containing many blood vessels and lymphatic vessels. The medulla also contains nerve fibers that help to control the function of the ovary.

Function

The primary function of the ovarian medulla is to support the function of the ovary by providing a network of blood and lymph vessels. These vessels supply the ovarian follicles with nutrients and oxygen, and remove waste products. The nerve fibers in the medulla also play a role in regulating the function of the ovary, including the release of eggs during ovulation.

Clinical significance

Abnormalities in the ovarian medulla can lead to a variety of medical conditions. For example, ovarian torsion can occur if the blood vessels in the medulla become twisted, cutting off the blood supply to the ovary. This is a medical emergency that requires immediate treatment. Other conditions, such as polycystic ovary syndrome, may also involve changes in the structure or function of the ovarian medulla.
