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 soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth.The soft palate is part of the palate of the mouth; the other part is the hard palate.
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
The functional vomeronasal system is found in all snakes and lizards, [22] and many mammals. Salamanders perform a nose-tapping behavior to presumably activate their VNO. [23] Snakes use this organ to sense prey, sticking their tongue out to gather scents and touching it to the opening of the organ when the tongue is retracted. [24]
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.
The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
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 ...
The raphe is a surface feature overlying - and indicating - the intermaxillary suture, and median palatine suture. [1]: 114-115 The greater palatine foramen may be palpated on either side about half way between the palatine raphe, and the palatal gingival margin of the 2nd or 3rd upper molar tooth.
