Following ovulation, what do the remains of the follicle form?
Primary follicle
Zygote
Corpus luteum
Oocyte
The Correct Answer is C
A. The primary follicle is an earlier stage in the development of the ovarian follicle, not the structure that forms after ovulation.
B. The zygote is the result of fertilization, formed when the sperm and egg unite, but it does not form from the follicle after ovulation.
C. The corpus luteum forms from the remains of the follicle after ovulation. It secretes progesterone to support early pregnancy or prepares to degenerate if pregnancy does not occur.
D. The oocyte is the egg cell itself, which is released during ovulation, but it is not the structure that forms from the follicle after ovulation.
