What is the function of cranial nerve I?

Cranial nerve I, also known as the olfactory nerve, is responsible for the sense of smell. Its function involves detecting and transmitting odors from the nasal cavity to the brain. The nerve contains specialized receptor cells in the olfactory epithelium lining the upper part of the nasal cavity. These receptors bind to specific odor molecules and generate electrical signals that are sent to the brain for interpretation. Dysfunction of the olfactory nerve is known as anosmia, which can have significant impacts on an individual's quality of life and ability to detect danger.
