Question

Non cellular layer is

• A. Theca is interna
• B. Membrana granulosa
• C. Corona radiata
• D. Zona pellucida

Answer 1

The correct option is D Zona pellucida

Zona pellucida is a non-cellular glycoprotein layer around the ovum.

Theca interna is the internal layer of the cells surrounding the primary oocyte in the tertiary follicle present in the ovary.

Membrana granulosa is made up of the granulosa cells, present in the inner coat of the large ovarian follicles.

Corona radiata is a cellular layer just adjacent to the zona pellucida layer in the ovum and derived from cumulus oophorus. So the correct answer is D.
