What does reflex arc mean?
Answer and explanation
Correct answer: Path of message in reflex action
A reflex arc is the specific neural pathway followed during a reflex action. A receptor detects a stimulus, the sensory neuron carries the impulse to the spinal cord, and a motor neuron carries the instruction to an effector such as a muscle. Thus, option A is correct because it describes the message pathway; the other options refer to routes of food, blood, or air, not nerve impulses.
