Which of the following best describes the function of the cranial nerves?
They transmit sensory and motor information between the brain and various parts of the head, neck, and body.

The conceptual relationship between the structure and function of special senses and the autonomic nervous system is best described as:
Special senses provide sensory input that influences autonomic responses.
The autonomic nervous system controls voluntary muscle movement in special senses.
Special senses and the autonomic nervous system operate independently without interaction.
The autonomic nervous system is responsible for processing sensory information from special senses.
