A chemical messenger usually produced within the hypothalamus, carried to the pituitary and then to other cells within the central nervous system (CNS). Neurohormones are similar to neurotransmitters except that they interact with a variety of cells, whereas neurotransmitters interact only with other neurons.
A hormone used in the function of the nervous system. For example, norepinephrine is the neurohormone mainly responsible for the function of sympathetic nerves.
The hormones produced by the hypothalamus.
A hormone produced in some nerve cells and secreted from the nerve endings.
Hormone secreted by nerve endings (e.g., vasopressin, released from nerve endings in the hypothalamus and released into the bloodstream from the posterior pituitary gland).
A hormone that is produced within specialized nerve cells and is secreted from the nerve endings into the circulation. Examples are the hormones oxytocin and vasopressin, produced within the nerve cells of the hypothalamus and released into the circulation in the posterior pituitary gland, and norepinephrine, released from ‘chromaffin tissue in the adrenal medulla.
