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.
Physical factors and
neurosecretion in the control of reproduction in Melampus (Mollusca: Pulmonata).
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).
Brain
neurosecretion during ovarian development and after ovariectomy in adult Acheta domesticus L.
Contribution a l'etude de la
neurosecretion et de l'endocrinologie chez les Cephalpodes.
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).
