There is dual tactile innervation of the human hairy skin: in addition to fast-conducting myelinated afferent fibers, there is a system of slow-conducting unmyelinated (C) afferents that respond ...

In the case of unmyelinated axons, the nerve impulse, or action potential, moves along the axon continuously. By contrast, in myelinated nerve fiber, currents can only occur where the axonal ...

The grey matter is mainly composed of neuronal cell bodies and unmyelinated axons. Axons are the processes that extend from neuronal cell bodies, carrying signals between those bodies. In the grey ...
