Cranial nerves are all connected to a part of the:

Heart
Brain surface
Spinal cord
Lungs

The correct answer is: Brain surface

C Spinal cord is incorrect because not all cranial nerves are connected to the spinal cord. The spinal nerves, not cranial nerves, are connected to the spinal cord. A: Heart is incorrect because cranial nerves are not connected to the heart. The heart is innervated by a separate network of nerves called the cardiac plexus. D: Lungs is incorrect because cranial nerves are not connected to the lungs. The lungs are primarily innervated by the vagus nerve, which is a cranial nerve, but not all cranial nerves are connected to the lungs.
