Explanation
The cranial nerves are a set of 12 paired nerves in the back of our brain. Cranial nerves send electrical signals between our brain, face, neck, and torso. The cranial nerves help us taste, smell, hear, and feel sensations. They also help us make facial expressions, blink our eyes and move our tongues. Mixed cranial nerves are the cranial nerves that contain sensory and motor nerve fibers. There are four such nerves in our peripheral nervous system: The trigeminal nerve (CN V), Facial nerve (CN VII), Glossopharyngeal nerve (CN IX), and Vagus nerve (CN X).

About Brain
The brain includes the cerebrum, cerebellum, brainstem, hypothalamus and medulla, each with distinct roles in sensation, movement and homeostasis. Questions connect major brain regions with their functions, reflex control and coordination, while distinguishing involuntary responses from hormonal regulation.
