Question

Which one of the following is responsible for the control of reflex action?

• A. Sensory nerves
• B. Motor nerves
• C. Sympathetic nervous system
• D. Central nervous system

Answer 1

The correct option is D Central nervous system

A reflex arc is a neural pathway, that controls an action reflex. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord (central nervous system). This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of sending signals through the brain.
