endocrine gland neuroendocrine cell BTO:0002691 BrendaTissueOBO Neuroendocrine cells are cells that receive neuronal input (neurotransmitters released by nerve cells) and, as a consequence of this input, release message molecules (hormones) to the blood. An example of a neuroendocrine cell is the cell of the adrenal medulla which releases adrenalin to the blood. The major center of neuroendocrine integration in the body is found in the hypothalamus and the pituitary gland. Here hypothalamic neurosecretory cells release factors to the blood.
