Physiology of paraneurons.
An attempt is made in this review to elucidate the functional characteristics of paraneurons. The secretory functions of neuron, neurosecretory cell and paraneuron consist of three main phases: secretion, transmission and reversion. Secretion can be divided into a steady state and an activated state. A paraneuron behaves characteristically in the active phase of secretion and in the phase of tr...
متن کاملThe physiology and cell biology of paraneurons.
This paper reviews the sequence of events in stimulus-secretion coupling in neurons and paraneurons which can be divided into three main steps: the reception of the stimuli, the conduction of excitation, and the extrusion of messenger substances. One physiological criterion of the paraneuron is that its conductile region is believed to be short enough to transmit the net electrogenesis to the o...
متن کاملConcept of paraneurons.
Paraneurons are those cells which have not been designated as neurons but are recognized as closely related to neurons on the basis of their fine structure (possession of neurosecretion-like and synaptic vesicle-like granules/vacuoles), metabolism (production of neurosecretion- and neurotransmitter-like substances) and origin (evidenced or proposed neuroectodermal). Some paraneurons are mainly ...
متن کاملUrogenital paraneurons in several mammals.
Amines and/or peptide-producing cells, deserving to be called paraneurons, were demonstrated in the urethro-prostatic complex of the man, rabbit, buffalo and sheep and in the uterine horns of the pig, horse and mouse, by means of histochemical, immunohistochemical, immunofluorescent and double labeling immunofluorescent techniques. In particular, the urethro-prostatic complex of the sheep conta...
متن کاملCCK-containing paraneurons in human adenomatous prostate.
The presence of CCK-containing neuroendocrine cells in human adenomatous prostates, and the colocalization of CCK together with serotonin in the same cell, have been demonstrated by means of an immunohistochemical technique and by a double labeling immunofluorescent staining. CCK-containing neuroendocrine cells had a focal distribution in the prostates and sometimes showed dendrite-like cytopla...
