How do cells in the ovary detect a hormone from

the brain?

(1) The brain sends a nerve impulse to the ovary.

(2) White blood cells bring the hormone to the

ovary.

(3) Receptor molecules on the cells of the ovary

bind with the hormone.

(4) Vacuoles within the ovary bind with the

hormone.

Hormones are produced an then circulate through the body systematically. The target organ (in this case the Ovary) has

receptors that react to the influence of the hormone through direct

interaction of the hormone and the receptor.

FSH (follicle stimulating hormone) CG (chorionic gonadotrophin) and

LH (Leutinizing Hormone) along with progesterone, prostiglandin and

estrogen

are hormones that create feedback between the pituitary gland

(brain) and the ovaries creating the reproductive cycle.

(3) Receptor molecules on the cells of the ovary

bind with the hormone.
