Cranial Nerve 2, also known as the Optic Nerve, plays a critical role in vision. It carries visual information from the retina of the eye to the brain for processing. This nerve is responsible for transmitting signals related to light, colors, shapes, and movement from the eye to the brain's visual centers. Any damage or impairment to Cranial Nerve 2 can result in various visual disturbances, including partial or complete vision loss. It is crucial for maintaining the sense of sight and coordinating proper visual perception.

Cranial nerve I, also known as the olfactory nerve, is responsible for the sense of smell in the human body. It transmits information from the nasal cavity to the brain, allowing individuals to detect and differentiate various odors. The olfactory nerve plays a vital role in our perception of the environment and can trigger emotional responses and memories through olfactory sensations.
