AXON-REFLEX

From Big Medical Encyclopedia

AXON-REFLEX (axon-reflex) — the reflex which is carried out on branchings of an axon without participation of a body of a nervous cell. The term is entered by the English physiologist of Langley (J. N. Langley, 1900) though the AXON-REFLEX was described by the Russian physiologist A. I. Babukhin (1877). Excitement at AKSON-REFLEKSE can extend on branchings as the spinal afferent fibers forming so-called polyvalent receptors in internals and on branchings of vegetative efferent fibers.

Distinguish preganglionic and postganglponarny AKSON-REFLEKSY. The long time was considered that on the AKSON-REFLEKSA mechanism the peripheral viscerovisceral reactions observed at switching off of c are carried out. N of page. In a crust, time the numerous evidence that the specified peripheral reactions often proceed as true peripheral reflexes which arch is formed by synoptic connection in vegetative gangliya afferent and efferent and, apparently, internuncial neurons are obtained. Thanks to true vegetative reflexes and AKSON-REFLEKSAM functional linkages of internals and vessels to a certain extent irrespective of c are carried out. N of page See also Reflex .
