What is usually the main control centre for reflex action?
Answer and explanation
Correct answer: Spinal cord
The spinal cord is usually the main integration centre for a reflex action because it provides a short pathway that produces a rapid protective response. Sensory information enters the spinal cord, is processed through an interneuron, and a motor impulse travels to the effector. Therefore option B is correct. The brain can receive information and may later interpret it, but the heart, liver and lung are not the usual control centres of a reflex arc.
