The Jugulo-omohyoid Lymph Node is a significant component of the human lymphatic system. It is located in the neck, specifically at the point where the omohyoid muscle crosses the internal jugular vein. This lymph node is part of the deep cervical group of lymph nodes and plays a crucial role in the body's immune response.

Anatomy[edit | edit source]

The jugulo-omohyoid lymph node is situated in the lower part of the neck, near the junction of the omohyoid muscle and the internal jugular vein. It is typically the size of a small pea and is embedded in the fascia that surrounds the neck muscles and veins.

Function[edit | edit source]

The primary function of the jugulo-omohyoid lymph node, like other lymph nodes, is to filter lymph fluid and trap foreign particles, including bacteria and viruses. This node is particularly involved in draining lymph from the tongue and the tonsils, which are common entry points for pathogens.

Clinical Significance[edit | edit source]

Enlargement or inflammation of the jugulo-omohyoid lymph node, known as lymphadenopathy, can be a sign of infection or disease. It is often examined during a physical examination of the neck, especially when conditions such as tonsillitis or oral cancers are suspected.
