II. Physiology
- Substances with odor (odorants) enter nose
- Nasal mucosa absorbs odorants
- Odorants stimulate olfactory receptors at the Cribiform Plate neuroepithelium
- Smell-related signals pass via the Olfactory Bulb to the olfactory cerebral cortex
III. Anatomy
-
Olfactory Nerve and Olfactory Bulb (Cranial Nerve 1)
- Primary transmission of Smell Sensation
-
Trigeminal Nerve (Cranial Nerve 5) - Ophthalmic and Maxillary Divisions
- Influence Temperature, irritation and sharpness sensations
