PERIPHERAL NERVES I
The distribution of nerve fibers differs for a deep muscle nerve vs. a superficial cutaneous nerve. C fibers in both represent afferent C and efferent (sympathetic) C axons.

Most peripheral nerves contain
both sensory and motor axons. The distribution of sensory and motor axon type differs
for terminal nerves innervating skeletal muscles
(muscle nerve) vs. terminal nerves innervating
skin, and joints (cutaneous nerves).
Although unmyelinated C fibers do not innervate the specialized skin or muscle mechano- receptors nor the motor units, C fibers represent the largest proportion of axons in a nerve (fig 24-13).
Velocities are for cats, humans conduct slower.
