Where do the neurons of the nuclei of the hypothalamus terminate?
precursor to ACTH
Corticotropin releasing hormone is released from the ______ nucleus of the hypothalamus.
vasopressin or ADH predominantly comes from which nucleus of the hypothalamus?

most abundant endocrine cell in the anterior pituitary
catalyzes the conversion of norepinephrine to epinephrine?
