MICROANATOMY

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

Detailed explanation-2: -Your olfactory nerve is the first cranial nerve (CN I). This nerve enables your olfactory system and sense of smell. Cranial nerve 1 is the shortest sensory nerve. It starts in your brain and ends in the upper, inside part of your nose.

Detailed explanation-3: -The olfactory nerves terminate in the nasal mucosa, which occupies a small surface on the roof of the nasal cavity. The lateral olfactory nerves (12–20) are found in the superior nasal concha. The medial olfactory nerves (12–16) descend along the nasal septum.

Detailed explanation-4: -Coffee and vanilla principally stimulate the olfactory cell receptors. Ammonia is a trigeminal nerve stimulator.

Detailed explanation-5: -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.
