The correct order from the plasma membrane of an oocyte outward is zona pellucida, granulosa cells, and then theca cells. The zona pellucida is a glycoprotein layer surrounding the plasma membrane of the oocyte, followed by granulosa cells that provide nutrients and signals to the oocyte, and finally the theca cells, which are located outside the granulosa cells and are involved in hormone production.
