The incisive papilla is an oval [1] [2] midline mucosal [2] prominence of the anterior hard palate [1] overlying the incisive fossa. [1] [3] [2] It is situated posteriorly to the central incisors, [2] and represents the anterior extremity of the palatine raphe. [1] The incisive papilla marks the position of the foetal nasopalatine canal. [1]
The palatine raphe (also median palatine raphe [1]) is a raphe of the oral cavity. It is a narrow, slight midline ridge extending anteroposteriorly across the palate, from the incisive papilla anteriorly to the palatine uvula posteriorly. [2]
The incisive foramen is a funnel-shaped opening in the bone of the oral hard palate representing the inferior termination of the incisive canal. [citation needed] An oral prominence - the incisive papilla - overlies the incisive fossa. [1] The incisive foramen is situated immediately behind the incisor teeth, and in between the two premaxillae.
The vomeronasal organ (VNO), or Jacobson's organ, is the paired auxiliary olfactory (smell) sense organ located in the soft tissue of the nasal septum, in the nasal cavity just above the roof of the mouth (the hard palate) in various tetrapods. [1]
The two incisive canals usually (in 60% of individuals) have a characteristic Y-shaped or V-shaped morphology: above, each incisive canal opens into the nasal cavity on either side of the nasal septum as the nasal foramina; below, the two incisive canals converge medially to open into the oral cavity at midline at the incisive fossa [1] as several incisive foramina.
It presents, close to its medial margin, the upper orifice of the incisive canal. The lateral border of the process is incorporated with the rest of the bone. The medial border is thicker in front than behind, and is raised above into a ridge, the nasal crest , which, with the corresponding ridge of the opposite bone, forms a groove for the ...
