Detailed explanation-1: -The secondary follicle soon transforms into a tertiary follicle which is characterised by a fluid-filled cavity called antrum. One of these tertiary follicles that undergoes further maturation is known as the Graafian follicle.
Detailed explanation-2: -It is a cavity around the ova that develops in the development of the Graafian follicle. This is also called the follicular antrum. It provides the required environment for the development of the oocyte. It is the combination of blood plasma and secretory product of granulosa and theca cells.
Detailed explanation-3: -As the secondary follicle develops, fluid is secreted by granulosa cells which contain the hormone estrogen. A fluid-filled space or cavity, which is called the antrum, develops in the follicle which is now called the tertiary follicle.
