*The nasal cavity is occupied to a large extent by '''''Nasal conchae'''''. These are turbinate bones which project into the nasal cavity with the purpose of supporting the [[Special Senses - Olfactory - Anatomy & Physiology|olfactory]] mucus membranes and increasing the respiratory surface area, creating turbulence within the passing air. This helps to filtrate and warm or cool the air that passes through.

*The Conchae are cartilagenous or ossified scrolls which arise from the ''ethmoid bone''. They are covered with mucous membrane, under which is a layer of anastomosing blood vessels.

The nasal conchae are more complex in animals with a better sense of smell, as they increase the surface area further.
