Here i have described about the cranial nerves their function and their supply to respective structures. 1. Olfactory Nerve: It is a type of sensory nerve, Supply: It supplies to the Olfactory Epithelium(cells) Function: Perception of smell from the nasal cavity. 2. Optic Nerve: It is a type of sensory nerve, Supply: Retina (ganglion cells) [...]

Cranial nerves: These are so called because they emerge through the foramina or fissures in the cranium and are covered by tubular sheaths derived from the cranial meninges. The cranial nerves are bundles or sensory (or) motor fibers that inervate muscles (or) glands, carry impulses from sensory receptors, (or) show a combination of both motor [...]
