The nasal cavity can be divided into the vestibule, respiratory and olfactory sections.
- Nasal vestibule. The nasal vestibule is the dilated area at the nostril opening.
- Respiratory section.
- Olfactory region.
- Para-nasal sinuses.
- Nasolacrimal ducts.
- Oral cavity.
- Mucosa of the olfactory system.
- Conchae (turbinate bones)

What structures are involved with the nasal cavity?
Structures of the olfactory system include: Nose: opening containing nasal passages that allows outside air to flow into the nasal cavity. Nasal cavity: cavity divided by the nasal septum into left and right passages. Olfactory epithelium: specialized type of epithelial tissue in nasal cavities that contains olfactory nerve cells and receptor nerve cells.
What is divides the nasal cavity into two?
The nasal septum divides the cavity into two cavities, also known as fossae. Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract .
