Question

Parasympathetic nervous system develops from region

• A. Thoracolumbar
• B. Craniosacral
• C. Cervical
• D. Lumbar

Answer 1

Answer: (B)

Craniosacral

The parasympathetic nervous system differs from the sympathetic nervous system in origin because the parasympathetic nervous system develops both in the brain and spinal cord while the sympathetic nervous system only develops in the spinal cord. The parasympathetic nervous system originates from the sacral region of the spinal cord and cranial nerves of III, VII, IX, and X. So, the development region is called craniosacral.

Hence, the correct answer is 'Craniosacral'.
