What is a cumulus oophorus cyst?
Cumulus oophorus refers to an appearance in the ovary in which multiple granulosa cells enlarge around a developing oocyte. These support cells (“cumulus cells”) serve multiple functions in the maturation of the oocyte.
What does the cumulus oophorus do?
Functions of the cumulus oophorus include coordination of follicular development and oocyte maturation. Mechanisms of the latter include stimulation of amino acid transport and sterol biosynthesis and regulation of oocyte gene transcription.
Where are cumulus oophorus located?
the follicle
At the base of the follicle is a small pedestal of cumulus cells, the cumulus oophorus, that projects from the follicular wall. The cumulus cells also surround the ovum.
What is the difference between cumulus oophorus and corona radiata?
The corona radiata is the innermost layer of the cells of the cumulus oophorus and is directly adjacent to the zona pellucida, the inner protective glycoprotein layer of the ovum. Cumulus oophorus are the cells surrounding corona radiata, and are the cells between corona radiata and follicular antrum.
Is cumulus an Oophorus?
The cumulus oophorus is de®ned as a group of closely associated granulosa cells, called cumulus cells, which surrounds the oocyte in the antral ovarian follicle.
Where are follicles located?
the ovaries
A small, fluid-filled sac in the ovary that contains one immature egg. There are thousands of follicles in the ovaries.
What does a follicle on your ovary mean?
Ovarian follicles are small sacs filled with fluid that are found inside a woman’s ovaries. They secrete hormones which influence stages of the menstrual cycle and women begin puberty with about 300,000 to 400,000 of them. Each has the potential to release an egg for fertilisation.
Is follicles in ovary normal?
The number of antral follicles varies every month. A woman is considered to have adequate or normal ovarian reserve if the antral follicle count is 6-10. If the count is less than 6 the ovarian reserve could be considered to be low, whereas a high reserve is greater than 12.
