WebOct 29, 2024 · An axon reflex is a nervous reaction that is triggered by an axon via its collaterals, the so-called axon collaterals. This process occurs without synaptic impulse transmission. General information. This section has been translated automatically. The axon reflex is characterized by a so-called "triple response", an inflammatory triple response ... WebThe axon arises from the cell body at a small elevation called the axon hillock. The proximal part of the axon, adjacent to the axon hillock, is the initial segment. The cytoplasm of the axon (axoplasm) contains dense bundles of microtubules and neurofilaments (Figs. 2.1 and 2.5A, B). These function as structural elements, and the … asthma book pdf WebConsequently, each axon was predetermined to connect to its target cell alone during development by the genotype, which is the collection of all genes of a mammal. That was a new idea that many researchers studied in depth and eventually the scientific community accepted the theory that chemical connection of axons to their target cells ...
