Anteriorly, the cartilaginous outer bar does not cover the vomeronasal organ laterally. The vomeronasal ducts are apparent at the anterior extreme of the vomeronasal organ, consisting of tubes on either side of the nasal septum that empty into each nasopalatine duct, separated from the nasal fossa proper (e.g., slice 31.3.2). Elongate, thin cartilages support each nasopalatine duct laterally, and line the posterior margins of each incisive foramen (e.g., slice 32.1.2; fig. 27).
