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.


Sagot :

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.
