neurosecretion

 [noor″ro-sĕ-kre´shun]
1. secretory activities of nerve cells.
2. a substance secreted by nerve cells. adj., adj neurosecre´tory.

neu·ro·se·cre·tion

(nū'rō-sē-krē'shŭn),
The release of a secretory substance from the axon terminals of certain nerve cells in the brain into the circulating blood. The secretory product may be a true hormone, for example, the antidiuretic hormone released from the axon terminals of the neurons that make up the supraoptic nucleus of the hypothalamus; in the case of the so-called releasing-factor neurons of the hypothalamus, the cell product is not a systemic hormone in its own right but elicits the release of trophic hormones by the anterior lobe of the hypophysis, substances that in turn stimulate peripheral endocrine glands to release their systemically active hormones.

neurosecretion

(no͝or′ō-sĭ-krē′shən, nyo͝or′-)
n.
1. The secretion of substances, such as hormones, by nerve cells.
2. A substance secreted by this process.

neu′ro·se·cre′to·ry (-krē′tə-rē) adj.

neu·ro·se·cre·tion

(nūr'ō-sĕ-krē'shŭn)
Therelease of a secretory substance from the axon terminals of certain nerve cells in the brain into the circulating blood.

neurosecretion

the process of secretion of hormones by nerve cells.

The perception of external stimulation in molluscs is captured and channeled by cells and/or highly specialized organs (thermal receptors, statoreceptors, and paleal sensory organ), located mainly on the edge of the bivalve mantle (Zaixo, 2003) which transmit the information from the periphery toward nerve centers (ganglia), that in response synthesize and release different types of chemical messengers or neurosecretions for controlling the activity of target tissues as a specific response (Mathieu et al.).
A comparative study on neurosecretion demonstrated by the alcian blue-alcian yellow technique in three terrestrial pulmonates (Stylommatophora).
Therefore, protein hydrolysate flowing into the small intestine is considered to directly stimulate CCK secretion by isolated mucosal cells of the small intestine (Nishi et al., 1998) or STC-1 cells in neurosecretion (Cordier-Bussat et al., 1997).
They explain both basic science and clinical aspects relating to the molecular basis of hormones; the hypothalamus and the concept of neurosecretion; the pituitary gland and its diseases; the testes and ovaries; the endocrine control of puberty and salt and water balance; hormones of pregnancy, parturition, and lactation; the adrenal glands; the thyroid gland, the islets of Langerhans and their hormones; diabetes; the gut-brain axis; hormones, endocrine tumors, and the gut; the parathyroids, the endocrine kidney, and calcium regulation; and the genetics of endocrine tumors.
Histopathological examination of the neurosecretory cells found a neurosecretion trapped inside the cells, despite it having passed to their axons.
Calcium plays an important role in vesicular exocytosis and in turn in neurosecretion. To understand the role of TRPC3 calcium channel in vesicular fusion we have examined TRPC3 localization and function in Vasopressin (VP) and oxytocin (OT) producing neurons of the hypothalamic Supra optic Nucleus (SON).
Inhibition of metamorphosis is mediated by hypothalamic neurosecretion of the tripeptide thyrotropin-releasing hormone, which controls the biosynthesis and release of the pituitary hormone prolactin (PRL) (24,26).

Recently, I modified this definition slightly to "the permanent cessation of the critical functions of the organism as a whole."[20] I made this modification in response to bona fide examples of patients considered dead by a whole-brain formulation who apparently retained hypothalamic neurosecretion of antidiuretic hormone sufficient to prevent diabetes insipidus.
The same type of result was observed in the neurosecretion of vasopressin (VP) and oxytocin (OT) in experiments with awake rats (39).
