    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
