Explanation: FSH is responsible for stimulating the growth and development of ovarian follicles in the ovaries.
Correct answer: Follicle-Stimulating Hormone- A. FSH and estrogen
- B. LH and estrogen
- C. FSH and LH
- D. Estrogen and progesterone
Explanation: FSH and LH, both produced by the anterior pituitary gland, regulate the menstrual cycle.
Correct answer: FSH and LH1184. In humans, only one ovum is usually discharged from the ovary at a time. This phenomenon is called?

- A. Endometrium
- B. Perimetrium
- C. Corpus luteum
- D. None of these
Explanation: After ovulation has occurred, the remains of the follicle forms the corpus luteum which is a structure involved in the secretion important…

Explanation: The zygote is formed in the oviduct and moves towards the uterus where it could be embedded.
Correct answer: Oviduct- A. Primary spermatocytes
- B. Spermatids
- C. Secondary spermatocytes
- D. Spermatogonia
Explanation: Spermatids are the end result of the process of meiosis. They, then, undergo specialization which includes growing flagella, and acrosomes…
