What membrane that covers the ovaries?

The membrane that covers the ovaries is called the germinal epithelium. It is a layer of cuboidal or columnar cells that serves as a protective covering for the ovarian surface. Beneath this layer, the ovaries contain the ovarian cortex and medulla, where the follicles and blood vessels are located. This epithelium is important for ovarian function and provides a barrier between the ovarian tissue and the peritoneal cavity.
