Keelevõrgus

Keelevõrgus, also known as the "tongue network," is a structural feature found on the surface of the tongue, consisting of a network of small, filamentous papillae. These papillae are specialized structures that contribute to the sensory and mechanical functions of the tongue. Keelevõrgus plays a crucial role in the perception of taste, manipulation of food, and articulation of speech.

The surface of the tongue is covered by various types of papillae, including filiform, fungiform, circumvallate, and foliate papillae. The keelevõrgus primarily involves the filiform papillae, which form a dense network across the dorsal surface. These papillae are keratinized and provide a rough texture, aiding in the mechanical processing of food and stimulating tactile sensation.

Structurally, keelevõrgus is characterized by an interconnected pattern resembling a mesh or net, composed of numerous fine epithelial fibers. This network supports the underlying taste buds located mainly on fungiform and circumvallate papillae and enhances the efficiency of sensory signal transmission to the brain.

Clinically, the integrity of the keelevõrgus can be affected by various conditions, such as infections, nutritional deficiencies, or injuries, leading to changes in the tongue’s appearance and function. Its presence and condition can be important indicators in oral health assessments.

Overall, keelevõrgus is an essential anatomical feature that underpins many vital functions of the tongue, from sensory perception to facilitating speech and swallowing. Its structure is a fine example of the complex design and specialization of oral tissues in humans.
