Nerve

Nerves are part of the peripheral nervous system. Afferent nerves convey sensory signals to the brain, for example from skin or organs, while efferent nerves conduct stimulatory signals from the brain to the muscles and glands.

These signals, sometimes called nerve impulses, are also known as action potentials: rapidly traveling electrical waves, which begin typically in the cell body of a neuron and propagate rapidly down the axon to its tip or "terminus."

The signals cross over from the terminus to the adjacent neuron through a gap called the synapse.

Peripheral nervous system: The peripheral nervous system or PNS, is part of the nervous system, and consists of the nerves and neurons that reside or extend outside the central nervous system--to serve the limbs and organs, for example. Unlike the central nervous system however, the PNS is not protected by bone or the blood-b...

Afferent nerve: In the nervous system, afferent nerves carry nerve impulses towards the brain. A touch or painful stimulus, for example, creates a sensation in the brain only after information about the stimulus travels there via afferent nerve pathways. Efferent nerves carry information away from the brain. In t...
