From which of the following layers the regeneration of endometrium take place :
Zona basalis Endometrium Superficial layer (2/3) Deep layer (1/3) It consists of stratum compactum stratum spongiosum These Layers are supplied by sprial which undergo vasocostriction during secretory phase | This causes necrosis or sloughing of these layers at the time of menstruation Stratum basale (Zona basalis) it is supplied by basllar aeries | During secretory phase these basilar aeries remain straight, so the blood supply stratum basale remains intact. Therefore this layer is not shed and during secretory phase it causes the regeneration.
Zona basalis
Zona pellucidum
Zona compacta
Zona spongiosum
