The interrelationships between the endocrine and the nervous systems are especially apparent in: a) a neuron in the spinal cord. b) neuron in the cerebral cortex. c) neurosecretory cell in the hypothalamus. d) digestive enzyme-producing cell in the pancreas. e) steroid-producing cell in the adrenal cortex.

c) neurosecretory cell in the hypothalamus

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.
