Cumulus oophorus

Cumulus oophorus (pronunciation: /kyo͞oˈmyo͞oləs oʊˈɒfərəs/), also known as the egg cloud or discus proligerus, is a cluster of cells that surround the oocyte both in the ovarian follicle and after ovulation.

Etymology

The term "cumulus oophorus" is derived from Latin, where "cumulus" means "heap" or "pile", and "oophorus" means "egg-bearing".

Function

The main function of the cumulus oophorus is to supply vital proteins to the oocyte during its growth and development. It also plays a crucial role in the process of fertilization, as it aids in the binding of the sperm to the zona pellucida, a glycoprotein layer surrounding the plasma membrane of the oocyte.
