- Primary follicle is formed by the primary oocyte arrested at Prophase I and enveloped by a layer of granulosa cells.
- These are then enveloped by a theca resulting in a secondary follicle, which further undergoes development resulting in the formation of a fluid-filled cavity called the antrum.

Structure of a Tertiary Follicle
Tertiary follicles are the advanced stage of ovarian follicle development in the ovary. They are characterized by the presence of a fluid-filled cavity called the antrum. This antrum is surrounded by granulosa cells and theca cells.
Antrum
The antrum is a fluid-filled cavity that forms within the tertiary follicle. It contains follicular fluid, which provides nourishment to the developing oocyte. The antrum plays a crucial role in the maturation of the oocyte and the preparation for ovulation.
Granulosa Cells
Granulosa cells are the somatic cells that surround the oocyte within the tertiary follicle. These cells secrete estrogen in response to follicle-stimulating hormone (FSH) from the pituitary gland. The granulosa cells also support the growth and development of the oocyte.
Zona Pellucida
The zona pellucida is a glycoprotein layer that surrounds the oocyte within the tertiary follicle. It plays a role in fertilization by mediating sperm binding and penetration during the process of conception.
In conclusion, the distinguishing characteristic of a tertiary follicle is the presence of an antrum, a fluid-filled cavity that supports the development and maturation of the oocyte. This structure is essential for the growth and eventual release of a mature oocyte during ovulation.
