If a person touches a hot surface and quickly pulls their hand away, which type of nerves are primarily responsible for sending the signal to move the hand?
Motor nerves
The reflex arc that pulls a hand away from a hot surface uses three neuron types: sensory neurons detect heat, interneurons in the spinal cord relay the signal and motor neurons act on the response.
The command to move muscles away from danger is carried from the central nervous system to the skeletal muscles by motor nerves.
Sensory nerves carry the heat signal inward, interneurons connect sensory and motor pathways, and autonomic nerves control involuntary organs, not voluntary withdrawal.
Hence, Motor nerves.
