Question

in ruptured ovum correct sequence of layers from inside to outside is - (I)zona pellucida -perivitelline -corona radiata (ii)Corona radiata-zona pellucida -perivitelline space (III) -perivitelline space-zona pellucida-corona radiata(iv) zona pellucida-corona -perivitelline space​

Answer 1

Answer:

option 3 is correct

Explanation:

In a ruptured ovum the correct sequence of layers from inside to outside is previtelline space zona pellucida and Corona radiata. Corona radiata is the outermost layer while previtelline space is innermost layer of a raptured secondary oocyte. Corona radiata is made by cumulus oophorus while zona pellucida is a glycoprotein layer. Previtelline space is the space between zona pellucida and cell membrane of ovum.
