Practice Question

How many pairs of spinal nerves are there in the human spinal cord?

Answer Choices:

Correct Answer:

31

Rationale:

🏵️ Humans have 31 pairs of spinal nerves emerging from the spinal cord.

🏵️ These are categorized into 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal pair.

🏵️ Each spinal nerve carries both sensory and motor fibers, making them mixed nerves.

🏵️ The number does not match 30, 40, or 42 because the distribution across vertebral regions adds up precisely to 31.

🏵️ These spinal nerves play a vital role in transmitting information between the central nervous system and the body.
