Answer 1

Cranial nerves are nerves that emerge from or enter the skull and are connected to the brain. They have specific names and functions, with some transmitting sensory information and others transmitting motor information. Some cranial nerves have a combination of sensory and motor fibers.

Step-by-step explanation:

Cranial nerves are nerves that emerge from or enter the skull (cranium) and are connected to the brain. Humans have 12 cranial nerves, each with a specific name and function. Some cranial nerves transmit sensory information, such as the olfactory nerve, which detects smells, while others transmit motor information, such as the oculomotor nerve, which controls eyelid movement.

Some cranial nerves have a combination of sensory and motor fibers, like the glossopharyngeal nerve, which is involved in both taste and swallowing.
