(Lingual veins labeled at center right.)<br /> | Drainsto = [[Internal jugular vein]]<br /> | Artery = [[Lingual artery]]<br /> | System = [[Circulatory system]]<br /> }}<br /> <br /> The &#039;&#039;&#039;lingual veins&#039;&#039;&#039; are a group of veins located under the [[tongue]] that are responsible for draining blood from the tongue and the floor of the mouth. These veins are part of the [[circulatory system]] and play a crucial role in the venous drainage of the tongue.<br /> <br /> ==Anatomy==<br /> The lingual veins are typically divided into three main branches:<br /> * The &#039;&#039;&#039;deep lingual vein&#039;&#039;&#039; (also known as the vena comitans nervi hypoglossi) runs alongside the [[hypoglossal nerve]] and drains the deep structures of the tongue.<br /> * The &#039;&#039;&#039;dorsal lingual veins&#039;&#039;&#039; drain the dorsal surface of the tongue.<br /> * The &#039;&#039;&#039;sublingual vein&#039;&#039;&#039; drains the floor of the mouth and the sublingual gland.<br /> <br /> These veins converge and eventually drain into the [[internal jugular vein]], which is a major vein in the neck that returns deoxygenated blood from the head to the heart.<br /> <br /> ==Function==<br /> The primary function of the lingual veins is to drain deoxygenated blood from the tongue and the floor of the mouth. This is essential for maintaining proper blood circulation and ensuring that metabolic waste products are efficiently removed from these tissues.<br /> <br /> ==Clinical significance==<br /> The lingual veins can be observed during a physical examination of the mouth and are often visible as blue lines under the tongue. They can become engorged or varicose in certain conditions, such as [[venous insufficiency]] or [[varicose veins]]. Additionally, the lingual veins are sometimes used for the administration of certain medications due to their accessibility and the rapid absorption of substances placed under the tongue.<br /> <br /> ==See also==<br /> * [[Lingual artery]]<br /> * [[Hypoglossal nerve]]<br /> * [[Internal jugular vein]]<br /> * [[Circulatory system]]<br /> <br /> ==References==<br /> {{Reflist}}<br /> <br /> [[Category:Veins of the head and neck]]<br /> [[Category:Anatomy]]<br /> [[Category:Circulatory system]]<br /> <br /> {{medicine-stub}}</div>
