A nerve is a bundle
of axons from
a variety of neurons. Neuron cell bodies are found only in the
CNS
or in ganglion bundles outside of the CNS. Ganglia are found as
part
of the structure of the autonomic
nervous
system. The direction of signals may be in opposite
directions
in a nerve within the different axons. For instance, many cranial
nerves carry axons from sensory neurons (AFFERENT) and axons carrying
signals
out to effectors.
