What is the correct directional path of a nerve impulse during a reflex action?
- A.Effector -> Motor neuron -> Spinal cord -> Sensory neuron -> Receptor
- B.Receptor -> Motor neuron -> Spinal cord -> Sensory neuron -> Effector
- C.Receptor -> Sensory neuron -> Spinal cord -> Motor neuron -> EffectorCorrect answer
- D.Spinal cord -> Receptor -> Sensory neuron -> Effector -> Motor neuron
Solution
In a reflex arc, the impulse travels from the receptor (sense organ) through a sensory neuron to the central nervous system (spinal cord), then via a motor neuron to the effector (muscle or gland).
