Neurosecretion is the release of extracellular vesicles and particles from neurons, astrocytes, microglial and other cells of the central nervous system. These neurohormones , produced by neurosecretory cells, are normally secreted from nerve cells in the brain that then circulate into the blood.
Today, neuroendocrinology embraces a wide range of topics that arose directly or indirectly from the core concept of neuroendocrine neurons. Neuroendocrine neurons control the gonads, whose steroids, in turn, influence the brain, as do corticosteroids secreted from the adrenal gland under the influence of adrenocorticotrophic hormone. The study ...
Neuroendocrine cells are cells that receive neuronal input (through neurotransmitters released by nerve cells or neurosecretory cells) and, as a consequence of this input, release messenger molecules into the blood.
A neurohormone is any hormone produced and released by neuroendocrine cells (also called neurosecretory cells) into the blood. [1] [2] By definition of being hormones, they are secreted into the circulation for systemic effect, but they can also have a role of neurotransmitter or other roles such as autocrine (self) or paracrine (local) messenger.
Herring bodies or neurosecretory bodies are structures found in the posterior pituitary.They represent the terminal end of the axons from the hypothalamus, and hormones are temporarily stored in these locations.
Alpha (α) motor neurons (also called alpha motoneurons), are large, multipolar lower motor neurons of the brainstem and spinal cord.They innervate extrafusal muscle fibers of skeletal muscle and are directly responsible for initiating their contraction.
Vasotocin is an oligopeptide homologous to oxytocin and vasopressin found in all non-mammalian vertebrates (including birds, fishes, and amphibians) and possibly in mammals during the fetal stage of development.
The mind's resilience is evaluated behaviorally, whereas the neuropathological damage is evaluated histologically, although damage may be estimated using blood-based markers and imaging methods. There are two models that can be used when exploring the concept of "reserve": brain reserve and cognitive reserve. These terms, albeit often used ...
