Which is a function of the cranial nerves? a.) control of the heart and the lungs b.) transmission of the sense of smell c.) sensation of the hands, neck, and arms d.) control of the central nervous system

The correct answer is B. A function of the cranial nerves is the transmission of the sense of smell.

Explanation:

The cranial nerves are part of the human peripheral nervous system, except the optic nerves, which, along with the retina, belong to the cerebellum (the remaining 11 axons extend outside the brain and are therefore considered part of the peripheral nervous system). In addition to the cranial nerves, the peripheral nerves include the spinal nerves and autonomic nerves.

There are a total of twelve pairs of cranial nerves, of which only the first and second originate from the cerebellum, the remainder from the brain stem. In addition, some brain nerves have lateral branches. Except for the olfactory nerves, the brain nerve passes into the thalamus. The olfactory nerve ends in the olfactory cortex.
