Related to neurohormonal: neurohormonal system
a hormone that stimulates neural mechanisms or is released when activated by neural stimuli.
A hormone formed by neurosecretory cells and liberated by nerve impulses (for example, norepinephrine).
neurohormone/neu·ro·hor·mone/ (noor´o-hor″mōn) a hormone secreted by a specialized neuron into the bloodstream, the cerebrospinal fluid, or the intercellular spaces of the nervous system.
A hormone secreted by or acting on a part of the nervous system.
a hormone produced in neurosecretory cells such as those of the hypothalamus and released into the bloodstream, the cerebrospinal fluid, or intercellular spaces of the nervous system. The product may or may not be a true systemic hormone such as epinephrine. When the hormone is not a true hormone, it may be a cell product that induces the release of a tropic hormone, which in turn stimulates an endocrine gland to release a systemic hormone. See also neuromodulator, neurotransmitter.
A hormone formed by neurosecretory cells and liberated by nerve impulses (e.g., norepinephrine).
neurohormonea hormone that is formed in neuron cell bodies and passes down their axons to be stored in the axon terminals until secreted into the blood stream in response to action potentials generated in these neurons (compare neurotransmitters). Examples are the hormones which are formed in nerve cells in the hypothalamus, pass down their axons to their terminals in the posterior pituitary, and are secreted there into the blood when appropriate stimuli activate the hypothalamic cells.
a hormone stimulating the neural mechanism.
