What is the difference between secondary follicle and tertiary follicle?

What is the difference between secondary follicle and tertiary follicle?

Secondary follicle is formed when primary follicle is surrounded by more layers of granulosa cells and form a new outer covering( theca). Similiarly, tertiary follicle is formed when secondary follicle develops a fluid filled cavity called antrum.It is the advanced form of secondary follicle.

What is the difference between primary follicle and tertiary follicle?

Primary follicles are formed from primordial follicles while secondary follicles are formed from primary follicles. Subsequently, the tertiary follicles are formed from secondary follicles. Both primary and secondary follicles lack a fluid-filled cavity called antrum while tertiary follicle has an antrum.

What is a secondary follicle?

A secondary ovarian follicle is a maturing ovarian follicle consisting of an oocyte surrounded by two or more layers of tall, supporting granulosa cells.

What is the function of the secondary follicle?

Secondary Follicle At this stage, a layer of cells outside the follicle become evident. These cells compose the theca interna and contribute to the production of estrogens. Recall that the production of estrogen requires both the cells of the theca interna and granulosa cells.

What is meant by primary follicle?

A follicle that has two layers of follicular cells is called a primary follicle. These cells continue to hypertrophy and proliferate to form many layers surrounding the oocyte. Eventually these cells become known as ‘granulosa’ cells. The granulosa cells will secrete progesterone after ovulation.

What is secondary follicle?

Secondary Follicle The secondary follicles look very similar to primary follicles, except that they are larger, there are more follicular cells, and there are small accumulations of fluid in the intracellular spaces called follicular fluid (nutritive fluid for the oocyte). These gradually coalesce to form an antrum.

What are the 4 types of follicles?
