In a reflex action, the hand moves away first and pain is felt later. What is the most suitable reason?
Answer and explanation
Correct answer: The spinal cord gives a rapid response and the brain receives information later
A reflex action is organised for speed and protection. Sensory information enters the spinal cord, which rapidly sends a motor command to withdraw the hand before conscious interpretation is completed. The same event is then communicated to the brain, where pain is consciously recognised. Thus option B is correct. The message does reach the brain; muscles do not interpret pain, and hormones are not responsible for this immediate pathway.
