Nerves are bundles of axons that conduct electrical impulses.
They are the body's communication system, transmitting signals between the central nervous system and the periphery.
Nerve pathways can be classified as sensory, motor and mixed sensory-motor pathways.
- Sensory nerves carry information from the sense organs to the central nervous system (CNS).
- Motor nerves transmit information from the CNS out to muscles and glands.
- Mixed sensory-motor nerves contain both types of information.
