*The Conchae are [[Bones and Cartilage - Anatomy & Physiology#Types of Cartilage|cartilage]]nous or ossified scrolls which arise from the [[Skull and Facial Muscles - Anatomy & Physiology#Ethmoid Bone (os ethmoidale|''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.

The nasal conchae are more complex in animals with a better sense of smell, as they increase the surface area of the [[Special Senses - Olfactory - Anatomy & Physiology|Olfactory]] region, further.

*There are dorsal and ventral conchae, the dorsal concha originating from the [[Skull and Facial Muscles - Anatomy & Physiology#Ethmoid Bone (os ethmoidale)|ethmoid bone]] and attaching to the maxilla, and the vental conchae originating from the [[Skull and Facial Muscles - Anatomy & Physiology#Maxilla|maxilla]] and extending further into the nasal cavity.
