The tongue can divide itself in dorsal and ventral surface. The dorsal surface is a stratified squamous keratinized epithelium, which is characterized by numerous mucosal projections called papillae. [11] The lingual papillae covers the dorsal side of the tongue towards the front of the terminal groove.
If talking about the skull, the dorsal side is the top. [38] The ventral (from Latin venter 'belly') surface refers to the front, or lower side, of an organism. [38] For example, in a fish, the pectoral fins are dorsal to the anal fin, but ventral to the dorsal fin. The terms are used in other contexts; for example dorsal and ventral gun ...
Sensation: The oral mucosa is richly innervated, meaning it is a very good at sensing pain, touch, temperature and taste. A number of cranial nerves are involved in sensations in the mouth including trigeminal (V), facial (VII), glossopharyngeal (IX) and vagus (X) nerves. The dorsum of the tongue is covered in specialised mucosa.
Posterior The direction toward the back of an individual's head, as opposed to anterior, which refers to the directions toward an individual's lips. The term posterior teeth refers to premolars and molars, as opposed to incisors and canines, which are anterior teeth. [1] [5] Proximal The surfaces of teeth that normally lie adjacent to another ...
Lingual papillae, particularly filiform papillae, are thought to increase the surface area of the tongue and to increase the area of contact and friction between the tongue and food. [2] This may increase the tongue's ability to manipulate a bolus of food, and also to position food between the teeth during mastication (chewing) and swallowing.
The tongue is moved side to side and inspected; it should be pink, moist, smooth and glistening. Assessment of the ventral (bottom) surface of the tongue is done by having the patient touch the tip of their tongue against the roof of their mouth. If healthy, it should have prominent veins and be pink, smooth, moist, glistening and free of ...
Coronals, previously called point-and-blade consonants, are consonants articulated with the flexible front part of the tongue.Among places of articulation, only the coronal consonants can be divided into as many articulation types: apical (using the tip of the tongue), laminal (using the blade of the tongue), domed (with the tongue bunched up), or subapical (using the underside of the tongue ...
In dorsal gestures, different parts of the body of the tongue contact different parts of the roof of the mouth, but it cannot be independently controlled so they are all subsumed under the term dorsal. That is unlike coronal gestures involving the front of the tongue, which is more flexible.
