nerve fibers
Impulse transmission cables
Nerve fibers are the long, thread-like extensions of nerve cells that transmit electrical impulses throughout the body.
Each fiber is an axon—the part of a neuron that carries signals away from the cell body to muscles, organs, or other neurons.
Bundles of nerve fibers form the nerves visible to the naked eye.
Damage to nerve fibers can cause numbness or paralysis.
