Question

Motor neuron of reflex arc carries impulse from

• A. Receptor to central nervous system
• B. Central nervous system to effectors
• C. Central nervous system to receptors
• D. Effectors to central nervous system

Answer 1

Answer: (B)

Central nervous system to effectors

Nerve cells (neurons) carry the message from the stimulated receptors to the correct effectors. A sensory neuron carries the message from the receptor to the central nervous system (the spinal cord and brain). A motor neuron carries the message from the central nervous system to the effector. This is a reflex arc

Hence, the correct answer is (B)
