1.The single process of a nerve cell that under normal conditions conducts nervous impulses away from the cell body and its remaining processes (dendrites). It is a relatively even filamentous process varying in thickness from about 0.25 to more than 10 mcm. In contrast to dendrites, which rar...
Define axon. axon synonyms, axon pronunciation, axon translation, English dictionary definition of axon. also ax·one n. The usually long process of a nerve fiber that generally conducts impulses away from the body of the nerve cell. ax′on·al adj.
Axon, portion of a nerve cell (neuron) that carries nerve impulses away from the cell body. A neuron typically has one axon that connects it with other neurons or with muscle or gland cells. Some axons may be quite long, reaching, for example, from the s
Axonal calibre differences of α-motor nerve fibres occuring in the course of nerve fibre division were studied in the nerve supplying the sternomastoid muscle of the rat. By using Karnovsky's method for histochemical demonstration of acetylcholinesterase activity, it was possible to distinguish ...
The nerve undergoes wallerian degeneration, with fragmentation of the axon distal to the site of injury. Motor and sensory paralysis occurs with associated atrophy of supplied muscles and loss of reflexes. After about 4 to 5 days, the distal segments of the nerve become inexcitable. In 1 to ...
The major integral membrane protein of peripheral nerve myelin is protein zero (P0), a member of a very large family of proteins termed the immunoglobulin gene superfamily. This protein makes up about 80% of the protein complement of PNS myelin. Interactions between the extracellular domains of ...

There are three main types of neurons in the human body that further perform specific and crucial functions: sensory, motor, and interneurons or relay neurons. The characteristic or feature that is common to these three different types of nerve cells is their structure, which is comprised of ...

In contrast, the neuropathology of this disease remains understudied despite the emerging evidence of neurological abnormalities induced by dystrophin loss. Using quantitative morphological analysis of nerve sections, we characterize axonopathies in the phrenic and hypoglossal (XII) nerves ofmice. We ...
