Name the various follicles you can find inside a typical ovary?

The ovaries, the female reproductive organs, contain various types of follicles responsible for the production, development, and release of eggs (ova). The primary follicles found inside a typical ovary include:

1. Primordial Follicles: These are the most basic and earliest stage of ovarian follicles. Each primordial follicle consists of an immature oocyte (egg) enclosed by a single layer of flattened granulosa cells.

2. Primary Follicles: As primordial follicles begin to develop, they are known as primary follicles. The granulosa cells surrounding the oocyte become cuboidal in shape and start to proliferate, forming multiple layers.

3. Secondary Follicles: Further development leads to the formation of secondary follicles. The granulosa cells continue to proliferate, forming the "cumulus oophorus" surrounding the oocyte. A fluid-filled cavity, known as the antrum, starts to appear within the follicle.

4. Graafian Follicles (Mature Follicles): The secondary follicles continue to grow and develop, becoming mature Graafian follicles. The antrum expands, and the cumulus oophorus, now known as the corona radiata, surrounds the oocyte. The Graafian follicle is ready for ovulation, releasing the oocyte into the fallopian tube.

5. Atretic Follicles: Many follicles undergo degeneration and cell death during various stages of development, resulting in atresia. These are known as atretic follicles. They appear as structures with degenerating granulosa cells and oocytes.

In addition to these primary follicles, there are several less commonly observed follicle types, such as primordial follicles with multiple oocytes (polyovular follicles), follicles with multiple layers of granulosa cells, or follicles that undergo abnormal development.
