In which example is a muscle working as an effector?
Answer and explanation
Correct answer: Removing the hand from a hot object
An effector is the organ that carries out the response after receiving a command from the nervous system. When a person touches a hot object, heat receptors detect the stimulus and the message is processed through a reflex pathway. Motor neurons then cause the arm muscles to contract, pulling the hand away. Thus option C shows muscles acting as effectors. The eye and nose in A and B mainly contain receptors, while D is a physiological change rather than a muscle response.
