Neuroendocrine is an adjective describing cells, tissues, or physiological processes that embody the functional link between the nervous system and the endocrine system, wherein nerve cells produce and secrete hormones into the bloodstream. These specialized cells act as transducers, effectively translating a neural, electrical signal into a systemic, hormonal message that targets distant tissues. This dual-mode of communication is vital for coordinating rapid, widespread, and sustained physiological responses throughout the body.
Origin
This descriptive term combines “neuro,” relating to nerves or the nervous system, with “endocrine,” pertaining to internal secretion of hormones. The concept arose from the anatomical and physiological discovery that certain nerve cells possess the capability to synthesize and release classical hormones, thereby blurring the traditional boundaries between the two major regulatory systems. It is a fundamental concept in the study of systemic homeostasis.
Mechanism
Neuroendocrine cells receive and integrate synaptic input, and upon reaching a threshold, they generate an action potential that triggers the release of stored neurohormones from their nerve terminals. Unlike classic neurotransmitters that act locally across a synapse, these neurohormones enter the systemic circulation to travel to and act upon distant target cells and organs. A primary example is the release of oxytocin and vasopressin from the posterior pituitary, which are synthesized by neuroendocrine cells in the hypothalamus.
