The answer to your question is D) zona pellucida. The zona pellucida is a thick glycoprotein-rich layer that surrounds the developing oocyte and is located between the oocyte and the granulosa cells. It plays a crucial role in fertilization as it prevents polyspermy, the entry of multiple sperm cells into the oocyte. The zona pellucida also plays a role in the early development of the embryo by helping to protect and nourish it. In some cases, abnormalities in the zona pellucida can result in infertility or other reproductive problems. It is important to note that understanding the anatomy and physiology of the female reproductive system is crucial for both healthcare professionals and individuals seeking to optimize their reproductive health.
