What is the correct function of sensory nerve and motor nerve in a reflex arc?
Answer and explanation
Correct answer: The sensory nerve carries the message to the spinal cord and the motor nerve carries the command to the effector
A reflex arc follows a definite direction. A receptor detects the stimulus, and the sensory neuron carries the resulting impulse from the receptor to the spinal cord, where the response is coordinated. The motor neuron then carries the outgoing command to an effector, such as a muscle, which produces the action. Hence option A is correct; the remaining choices assign unrelated plant or body functions to nerves.
