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.
Anterior (from Latin ante ' before ') describes what is in front, and posterior (from Latin post ' after ') describes what is to the back of something. [9] For example, for a dog the nose is anterior to the eyes and the tail is considered the most posterior part; for many fish the gill openings are posterior to the eyes and anterior to the tail.
Although technically referring only to anterior teeth (where the lips (labia) are present instead of cheeks), use of the term labial has inaccurately extended to all teeth, anterior and posterior (instead of vestibular). [1] [5] Lateral A tooth which is away from the midline, such as lateral incisor, [1] or the sides of a tooth. [6] Lingual
Examples of depapillating oral conditions include geographic tongue, median rhomboid glossitis and other types of glossitis. The term glossitis, particularly atrophic glossitis is often used synonymously with depapillation. Where the entire dorsal surface of the tongue has lost its papillae, this is sometimes termed "bald tongue". [4]
The posterior view contains, from superior to inferior, the cervical region encompassing the neck, the scapular region encompassing the scapulae and the area around, the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks.
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.
These are present mostly at the dorsal surface of the tongue, as well as at the sides. Innervated by facial nerve. Foliate papillae - these are ridges and grooves towards the posterior part of the tongue found at the lateral borders. Innervated by facial nerve (anterior papillae) and glossopharyngeal nerve (posterior papillae).
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
