Question

What are the significance of a reflex arc?

Answer 1

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. ... However, the brain will receive the sensory input while the reflex is being carried out and the analysis of the signal takes place after the reflex action.

Reflex actions are sudden, involuntary reactions of the body in response to stimuli. They occur without the involvement of the conscious areas of the brain. Therefore, all reflex actions are unconscious actions. Somatic nervous system is responsible for reflex arcs.
