Question

Reflex action (withdrawal of hand from heat source) is controlled by

• A. Sympathetic nervous system
• B. Autonomic nervous system
• C. Spinal cord
• D. Peripheral nervous system
• E. Craniosacral outflow

Answer 1

Answer: (C)

Spinal cord

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 spinal motor neurons without the delay of routing signals through the brain.

Hence the correct answer is (C)
