Deep cervical lymph node

Deep Cervical Lymph Nodes

The Deep cervical lymph nodes are a group of lymph nodes located along the length of the internal jugular vein on either side of the neck. They are part of the lymphatic system, which plays a crucial role in the body's immune response.

Anatomy

The deep cervical lymph nodes are divided into two groups: the superior deep cervical lymph nodes and the inferior deep cervical lymph nodes. The superior group is located around the upper third of the internal jugular vein, while the inferior group is located around the lower two-thirds of the vein.

Function

The primary function of the deep cervical lymph nodes is to filter lymph - a clear, watery fluid that carries white blood cells, especially lymphocytes, throughout the body. These lymph nodes also play a vital role in the body's immune response, as they are responsible for producing and storing cells that fight infection and disease.

Clinical Significance

Enlargement of the deep cervical lymph nodes, known as lymphadenopathy, can be a sign of various medical conditions, including infections, autoimmune diseases, and cancers such as lymphoma and metastatic cancer. Therefore, palpation of these lymph nodes is an important part of the physical examination in many clinical scenarios.
