Answer:
c) neurosecretory cell in the hypothalamus
Step-by-step explanation:
Hypothalamus is the small region of the brain and is present below the thalamus. It has neurosecretory cells that secrete regulatory hormones. The hypothalamic portal system carries these hormones to the anterior pituitary gland. In the hypophyseal portal system, the blood flows from capillaries in the hypothalamus into the portal veins and carry the blood to the capillaries of the anterior pituitary and allow the hypothalamus to control the secretion of hormones from the anterior pituitary.
