ᴀɴsᴡᴇʀ:

Structure of Graafian follicle :

Graafian follicle is a mature ovarian

follicle. An eccentric secondary oocyte is

surrounded by a non-cellular layer of zona

pellucida secreted by the vitelline membrane

of oocyte. The outermost protective and fibrous

covering is called theca externa. Inner to it is

cellular theca interna. It produces the hormone

estrogen. Inner to the theca interna, the follicular

cells form the membrana granulosa. From the

membrana granulosa the cells differentiate

into discus proligerus and the corona radiata

cells. Cumulus oophorus is the term used for

the oocyte and surrounding granulosa cells . A

fluid filled cavity called antrum lies between

the oocyte and the membrana granulosa. It is

filled with a fluid called liquor folliculi.
