Nasolabial lymph node

Nasolabial lymph node is a type of lymph node located in the nasolabial fold, which is the crease running from the side of the nose to the corner of the mouth. It is part of the lymphatic system, which plays a crucial role in the body's immune response.

Anatomy

The nasolabial lymph node is situated superficially, making it easily palpable during physical examination. It drains lymph from the areas of the face around the nose and mouth, particularly the nasolabial fold.

Function

Like all lymph nodes, the nasolabial lymph node filters lymph, a clear fluid that circulates through the lymphatic system carrying cells that help fight infection and disease. It plays a crucial role in the body's immune response by producing and storing cells that fight infection and disease.

Clinical significance

Swelling or enlargement of the nasolabial lymph node, known as lymphadenopathy, can be a sign of infection, immune disease, or cancer in the areas of the face it drains. It is often examined during a physical examination for signs of these conditions.
