General Anatomy > Respiratory system > Nose > Nasal cartilages > Vomeronasal cartilage



Immediately over the incisive canal at the lower edge of the cartilage of the septum lies a depression called the nasopalatine recess. In the septum close to this nasopalatine recess, a minute orifice may be discerned; it leads backward into a blind pouch, the rudimentary vomeronasal organ of Jacobson, which is supported by a strip of cartilage, the vomeronasal cartilage. This organ is well-developed in many of the lower animals, where it apparently plays a part in the sense of smell, since it is supplied by twigs of the olfactory nerve and lined by epithelium similar to that in the olfactory region of the nose.
