Which portion of the nervous system is in charge of reflexes?

 

Solution:

Concept: An action reflex is controlled by a reflex arc, which is a neurological circuit. 

The majority of sensory neurons in higher animals do not flow directly into the brain, but rather synapse in the spinal cord (central nervous system). 

This property permits reflex actions to happen quickly by stimulating spinal motor neurons without having to wait for messages to travel via the brain.
