Final answer:
The olfactory nerve is responsible for carrying smell information from the nose to the brain, allowing us to detect and interpret various odors.
Step-by-step explanation:
The function of the olfactory nerve is related to the sense of smell. This nerve is responsible for carrying smell information from the nose to the brain. When odor molecules stimulate the olfactory receptors in the nose, nerve impulses are sent via the olfactory nerve to the brain, where the brain interprets these signals as specific smells. This allows us to detect and differentiate between the vast array of odors in our environment. Taste and smell are interconnected as they are both chemosensory perceptions, but the olfactory nerve is dedicated solely to the olfactory system, which is distinct from the gustatory system responsible for the sense of taste.
