The Role of the Nervous System in Sensing and Reacting

The sensory nervous system gathers data from every receptor.
The central nervous system processes, filters, and decides.
Motor neurons carry the brain’s response back to muscles.
Reflexes bypass the brain entirely for speed.
The spinal cord acts as the main communication highway.
Neurotransmitters pass messages between billions of neurons.
Sensory and motor systems operate in perfect feedback cycles.
Damage to sensory nerves distorts perception and movement.
Myelin sheaths speed impulses like electrical insulation.
The nervous system turns perception into purposeful action.
