In a reflex action, control mainly occurs through which part?
Answer and explanation
Correct answer: Spinal cord
A reflex action must occur quickly to protect the body. In a typical reflex arc, the sensory impulse enters the spinal cord, is processed through an interneuron, and a motor impulse is sent to the effector muscle. The brain may receive information afterward, but it is not required to initiate the immediate response. Therefore, option A, the spinal cord, is correct; the heart, liver, and stomach do not serve as the main reflex-control centre.
