axon signals travel all the way down to the lowest part of the body
axons
On the outer parts
Spinal nerves are said to be mixes because their posterior roots contain sensory axons and their anterior roots contain motor axons.
the what? root of a spinal nerve consists of motor neuron axons
myelinated axons
unmyelinated axons.
axons of sensory neurons
It is a bundle of nerve fibers (technically called axons).
Ventralventral root
The part of a spinal nerve that contains only sensory neurons is called the ventral root. There's also the axons of motor neurons and axons of sensory neurons.
Schwann cells make the myelin sheath that encloses some axons
A group of axons in the CNS is most likely referring to the tracts of neurons that are found in the spinal cord.
