Study Notes
Upper Respiratory System - Rhinarium
- The rhinarium is the moist part of the nose, playing a crucial role in the respiratory system.
- External nares, also known as nostrils, are the external openings of the respiratory tract.
- The direct airflow through the nostrils helps prevent the inhalation of foreign bodies.
- The philtrum is a vertical groove located between the sides of the nose and the upper lip.
- Alar folds, also referred to as "wing folds," are flaps of skin on the outer aspect of the nares.
- The alar folds help direct air for olfaction, which is the process of smelling or perceiving odors.

Nasal Cavity Structure
- Extends from the nares to the pharynx
- Divided into two sides by the nasal septum
- Floor of the nasal cavity is formed by the hard palate
Nasal Turbinates
- Make the air turbulent to increase the surface area for air to come into contact with the nasal mucosa
- Remove particles from the air
- Warm the air up
Nasal Mucosa
- Lining of the nasal cavity is composed of respiratory mucosa
- Respiratory mucosa is a type of ciliated columnar epithelium with goblet cells
- Functions:
- Warms and moistens the air
- Traps foreign particles
- Produces mucus through goblet cells

Nasal Cavity and Turbinates
- Turbinates, also known as conchae, are bone and cartilage folds in the nasal cavity
- The shape of turbinates causes air to become turbulent in the nasal cavity
Functions of Turbinates
- Warming air: heat exchange with tissues in the nasal cavity
- Humidifying air: by adding moisture from mucus and other fluids in the nasal cavity
- Filtering: removing foreign particles from the air by trapping them in mucus
