Each nerve cell has one axon, which can be over a foot long. A nerve cell communicates with another nerve cell by transmitting signals from the branches at the end of its axon. In the peripheral nervous system, the larger (myelinated) axons are surrounded by a myelin sheath formed by ...

The signal always travels in the same direction - the signal comes into the neuron through the dendrites, through the cell body (soma), to the axon, and then out the terminal buttons to the dendrites of the next neuron. In this way information travels all around your body by going from ...
David A. McCormick, in From Molecules to Networks (Third Edition), 2014 This suggests that the squid giant axon should have a resting membrane potential of −62 mV. In fact, the resting membrane potential may be a few millivolts hyperpolarized to this value through the operation of the...

Neurons are the cells that gather information in the form of impulses and send them throughout the body. The neuron is made up of thecell body, thedendrites, and theaxon. Theaxon, also called the nerve fiber, resembles a long, threadlike fiber. Most neurons only have a singleaxon. In ...
In the central nervous system, axonin 1 is present in sensory pathways, such as fibers of the dorsal funiculi in the spinal cord and the optic pathway. However, axonin 1 is only expressed on growing nerve fibers. Late in embryonic development, it is present only on a small population of...
The surface area of an axon can be several thousand times the surface area of the parent cell body. Axons are sometimes referred to asnerve fibers,although strictly speaking, a nerve fiber includes both the axon and a sheath that is provided by support cells (described in a subsequent ...
