    9. Classification by myelination A fibers - Have the greatest amount of myelination and fastest conduction speeds (300 mph) -Carry sensory info from the skin and joints -Carry motor info to skeletal muscles B fibers -Lightly myelinated with conduction speeds of about 30 mph. -Carry sensory and motor info for internal (visceral) organs and some info from skin C fibers -Unmyelinated with conduction speeds of about 2 mph. -Not wrapped by Schwann cells, but can be supported by them. -Carry sensory and motor info for internal (visceral) organs.
