MICROANATOMY

Detailed explanation-1: -Neuroanatomy, Cranial Nerve 1 (Olfactory)

Detailed explanation-2: -Cranial nerve 1 is a special somatic afferent nerve which innervates the olfactory mucosa within the nasal cavity. It carries information about smell to the brain. The many branches of the olfactory nerve, called fila olfactoria, pass from the nasal cavity through the cribriform plate of the ethmoid bone.

Detailed explanation-3: -The olfactory nerve is a solely sensory nerve and conveys the sense of smell. Its receptors are located in the olfactory mucosa under the roof of the nasal cavity.

Detailed explanation-4: -The primary olfactory nerve function is to help you smell and taste foods. Your olfactory nerve stems from your olfactory epithelium, which comes from your nasal pits. From birth, your olfactory nerve’s origin goes on to your nose and primary palate.
