AnswerClick to flip back
A
Message is always carried to brain.
💡 Explanation:
A reflex arc is a neural pathway that controls a reflex action. The key characteristic is that the impulse travels from sensory neuron to motor neuron via interneuron in the spinal cord, without necessarily going to the brain. This allows for rapid involuntary responses. Option B is false because reflex arcs can bypass the brain entirely.
