kielenala

Kielenala is a Finnish term that translates to "under the tongue" or "sublingual" in English. It refers to the anatomical region located beneath the tongue. This area is characterized by its rich vascularization, meaning it has a dense network of blood vessels. This vascularity is significant for medical and physiological reasons.

In medicine, the sublingual route is a common method of administering certain medications. Drugs taken sublingually are placed under the tongue, where they are absorbed directly into the bloodstream through the thin mucous membranes. This bypasses the digestive system, allowing for faster absorption and a more rapid onset of action compared to oral administration. Examples of medications commonly administered sublingually include nitroglycerin for angina and certain benzodiazepines for anxiety or seizures.

The sublingual space also contains important anatomical structures, such as the lingual frenulum, a fold of mucous membrane that attaches the underside of the tongue to the floor of the mouth. Several salivary glands, specifically the sublingual glands, are also located in this region. These glands contribute to saliva production, which plays a vital role in digestion, lubrication, and oral hygiene. The rich blood supply in the kielenala area facilitates efficient absorption and also makes it a sensitive area.
