Why is a reflex action faster than a voluntary action?
Answer and explanation
Correct answer: Because its rapid coordination often occurs at the spinal-cord level
The governing concept is the reflex arc. In a protective reflex, a receptor detects a stimulus, a sensory neuron carries the impulse to the spinal cord, and a motor neuron quickly activates an effector. The response can begin before the brain completes conscious analysis, so option A is correct. Hormonal transport is generally slower, and the other choices involve unrelated systems.
