Cranial nerves are the paired nerves of the peripheral nervous system that connect the muscles and sense organs of the head and thoracic region directly to the brain. In mammals, there are 12 pairs of cranial nerves- olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory and hypoglossal.

So, the correct answer is '12'.
