Growth and maturation of graafian follicle is controlled by - [MP 95]...
Answer:
The growth and maturation of the Graafian follicle, which is the mature ovarian follicle containing the egg, is controlled by the FSH-LH (Follicle-stimulating hormone and luteinizing hormone) axis. Here is a detailed explanation:
FSH (Follicle-stimulating hormone):
- FSH is secreted by the anterior pituitary gland.
- It stimulates the growth and development of the Graafian follicle in the ovary.
- FSH acts on the granulosa cells of the follicle, promoting their proliferation and the production of estrogen.
LH (Luteinizing hormone):
- LH is also secreted by the anterior pituitary gland.
- As the follicle matures, the levels of estrogen produced by the granulosa cells increase.
- The surge in estrogen levels triggers a positive feedback loop on the anterior pituitary gland, causing a sudden increase in LH secretion.
- The surge in LH promotes the final maturation of the Graafian follicle, leading to ovulation.
Summary:
- FSH stimulates the growth and development of the Graafian follicle.
- LH triggers the final maturation of the follicle and ovulation.
Therefore, the correct answer is option A: FSH-LH.
