axon

[ˈæksɒn]

axon Definition

a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body.

Using axon: Examples

Take a moment to familiarize yourself with how "axon" can be used in various situations through the following examples!

• Example

  The axon carries signals away from the neuron's cell body.

• Example

  Damage to the axon can cause communication problems between neurons.

• Example

  Axons are covered in myelin, which helps speed up the transmission of electrical signals.

Phrases with axon

• axon terminal

  the end of an axon that forms a synapse with a target cell

  Example

  The axon terminal releases neurotransmitters that bind to receptors on the target cell.

• axon hillock

  the region of the neuron where the axon originates

  Example

  The axon hillock is the site where the neuron integrates incoming signals and decides whether to fire an action potential.

• axon guidance

  the process by which developing axons are directed to their targets

  Example

  Axon guidance is critical for the proper wiring of the nervous system.

Origins of axon

from Greek 'axios', meaning 'axis'

Summary: axon in Brief

An 'axon' [ˈæksɒn] is a long, slender projection of a nerve cell that conducts electrical impulses away from the neuron's cell body. It is covered in myelin, which helps speed up the transmission of electrical signals. Phrases like 'axon terminal' and 'axon hillock' refer to specific parts of the axon, while 'axon guidance' denotes the process by which developing axons are directed to their targets.
