Dorsal lingual veins

Dorsal Lingual Veins

The Dorsal Lingual Veins are a group of veins located on the dorsum (upper surface) of the tongue. They are responsible for draining blood from the tongue and are part of the venous system of the head and neck.

Etymology

The term "Dorsal Lingual Veins" is derived from the Latin words 'dorsum' meaning 'back' and 'lingua' meaning 'tongue'. Thus, the term literally translates to 'veins at the back of the tongue'.

Anatomy

The Dorsal Lingual Veins originate from the venous plexus on the dorsum of the tongue. They run along the tongue's surface towards its base, where they drain into the internal jugular vein via the lingual vein.

Function

The primary function of the Dorsal Lingual Veins is to drain deoxygenated blood from the tongue and transport it back to the heart. This is part of the body's overall circulatory system, which ensures that oxygen and nutrients are delivered to the cells, and waste products are removed.

Clinical Significance

The Dorsal Lingual Veins can be affected by various medical conditions. For instance, they can become enlarged or varicose due to high venous pressure, a condition known as lingual varicosities. They can also be affected by tongue cancer, as the cancerous cells can invade the veins and block blood flow.
