2. A long fiber of a nerve cell (a neuron) that acts somewhat like a fiber-optic cable carrying outgoing (efferent) messages.
The neuron sends electrical impulses from its cell body through the axon to target cells. Each nerve cell has one axon. An axon can be over 20 cm (a foot) in length, which for the human body is remarkably long.
This makes them ideal for operating on subcellular structures; such as, the axon, the long tail by which a neuron sends information to its neighbors and which are far too small for even the finest robotic surgical hands to maneuver.
An axon is a long fiber of a nerve cell (neuron) that acts somewhat like a fiber-optic cable to carry out-going messages.
The neuron sends electrical impulses from its cell body thorough the axon to target cells. Each nerve cell has one axon. An axon can be over a foot long.
Axons terminate in synapses, junctions with other nerve cells, muscles, or glands.
