nerve pathways
Signal transmission channels
Nerve pathways are the routes along which electrical signals travel through the nervous system, connecting different parts of the brain, spinal cord, and body.
A pathway consists of chains of neurons that relay information—sensory pathways carry signals from receptors to the brain, while motor pathways transmit commands from the brain to muscles.
Damage to nerve pathways can cause numbness or paralysis.
The term appears in medical contexts discussing how the body processes sensation, movement, and reflexes.
