In human being, the number of cranial nerves are:
Correct answer: C. 12 pairs
- A. 8 pairs
- B. 10 pairs
- C. 12 pairs
- D. 31 pairs
Explanation
Humans have 12 pairs of cranial nerves that emerge directly from the brain, each designated with a specific function. These nerves are classified as sensory, motor, or mixed, based on their primary functions. Option C is correct as it accurately reflects the number of cranial nerve pairs. Option A (8 pairs) and Option B (10 pairs) are incorrect as they underestimate the actual number. Option D (31 pairs) is incorrect because it refers to the number of spinal nerve pairs, not cranial nerves.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
