Number of cranial nerve found in man is

The correct answer is B. 12 pair.

Cranial nerves are 12 pairs of nerves that emerge directly from the brain, in contrast to spinal nerves, which emerge from the spinal cord. Cranial nerves are numbered according to their position relative to the forebrain, midbrain, and hindbrain.

The 12 cranial nerves are:

• Olfactory nerve (I): Smell
• Optic nerve (II): Vision
• Oculomotor nerve (III): Eye movement
• Trochlear nerve (IV): Eye movement
• Trigeminal nerve (V): Facial sensation, chewing
• Abducens nerve (VI): Eye movement
• Facial nerve (VII): Facial expression, taste, salivation
• Vestibulocochlear nerve (VIII): Hearing, balance
• Glossopharyngeal nerve (IX): Taste, swallowing, salivation
• Vagus nerve (X): Pharynx, larynx, heart, lungs, stomach, intestines
• Spinal accessory nerve (XI): Shoulder movement
• Hypoglossal nerve (XII): Tongue movement

The cranial nerves are essential for many important functions, including vision, hearing, smell, taste, facial expression, swallowing, speaking, and movement of the eyes, head, and neck.
