inal answer:
Cranial nerve I, the olfactory nerve, is responsible for the sensory system related to the sense of smell.
Step-by-step explanation:
Cranial nerve I, also known as the olfactory nerve, corresponds to the sensory system for the sense of smell. It conveys specific sensory information from the olfactory receptors in the nose directly to the brain. This nerve is entirely composed of sensory axons and does not contain any motor fibers, distinguishing it from some other cranial nerves which may contain a mix of both sensory and motor fibers.
