Which example shows the correct relation between control centre and effector?
Answer and explanation
Correct answer: Spinal cord forms the message and muscle pulls the hand away
In a withdrawal reflex, the spinal cord acts as the rapid control centre that receives and processes the sensory signal, while a skeletal muscle acts as the effector. The muscle contracts and pulls the hand away from the harmful stimulus. Thus option A represents the correct relationship, although the spinal cord coordinates the response rather than literally creating the original stimulus message. The other pairs assign impossible functions.
