Anatomy & Physiology Question #40
What does a reflex arc contain?
- Sensory neuron
- Sensory reception
- Motor neuron
- Gray matter
- White matter
The correct answers are A, B, and C. A reflex occurs when nerve impulses travel over a simple neuron. It elicits a pathway called a reflex arc. Reflex arcs have five basic systems: receptors, sensory neurons, interneurons, motor neurons, and effectors. A reflex arc does not contain gray or white matter.
