The tongue is an important accessory organ in the digestive system. The tongue is used for crushing food against the hard palate, during mastication and manipulation of food for softening prior to swallowing. The epithelium on the tongue's upper, or dorsal surface is keratinised. Consequently, the tongue can grind against the hard palate ...
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]
These two terms, used in anatomy and embryology, describe something at the back (dorsal) or front/belly (ventral) of an organism. [2] The dorsal (from Latin dorsum 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top. [38] The ventral (from Latin venter 'belly ...
The taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of lingual papillae; all except one contain taste buds: Fungiform papillae - as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section. These are present mostly at the dorsal surface of the ...
The dorsal lingual branches of lingual artery consist usually of two or three small branches which arise beneath the hyoglossus. They ascend medially to the back part of the dorsum of the tongue. [5] They supply the mucous membranes, the glossopalatine arch, the tonsil, soft palate, and epiglottis; anastomosing with the vessels of the opposite ...
Masticatory mucosa, keratinized stratified squamous epithelium, found on the dorsum of the tongue, hard palate, and attached gingiva. Specialized mucosa, specifically in the regions of the taste buds on lingual papillae on the dorsal surface of the tongue; contains nerve endings for general sensory reception and taste perception. [8]
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 ...
The dorsal lingual veins are some of the lingual veins.They provide venous drainage to the dorsum of the tongue, and the sides of the tongue. Between the hyoglossus and genioglossus, dorsal lingual veins unite with those lingual veins that are venae comitantes of the lingual artery; these consolidated lingual veins then empty into the internal jugular vein proximal to the greater cornu of ...
