A neural pathway that controls an action reflex is called:
Correct answer: B. Reflex arc
- A. Nerve cell
- B. Reflex arc
- C. Receptor cells
- D. Mixed nerve
Explanation
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain but synapse in the spinal cord. This allows for faster reflex actions to occur by activating the spinal motor neurons without the delay of routing signals through the brain.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
