Which anterior pituitary hormone is not paired with its correct function?
A. LH stimulates the ovaries to secrete estrogen.
B. FSH stimulates the development of egg cells in the ovaries.
C. LH stimulates ovulation of a mature egg.
D. FSH initiates sperm production in the testes.
The correct answer and explanation is:
The correct answer is A. LH stimulates the ovaries to secrete estrogen.
Explanation:
- A. LH stimulates the ovaries to secrete estrogen is incorrect because it is actually FSH (Follicle-Stimulating Hormone) that primarily stimulates the ovaries to produce estrogen. LH (Luteinizing Hormone) plays a role in triggering ovulation, but it does not directly stimulate estrogen production.
- B. FSH stimulates the development of egg cells in the ovaries is correct. FSH is involved in the growth and maturation of ovarian follicles, which contain the egg cells.
- C. LH stimulates ovulation of a mature egg is correct. LH is responsible for triggering ovulation, which is the release of a mature egg from the follicle in the ovary.
- D. FSH initiates sperm production in the testes is correct. FSH stimulates the Sertoli cells in the testes, which are essential for the production of sperm.
In summary, FSH is involved in the secretion of estrogen, egg cell development, and sperm production, while LH plays a critical role in ovulation and the regulation of estrogen levels indirectly.
