Cervical lymph nodes

Cervical lymph nodes are a type of lymph node found in the neck. They are part of the lymphatic system, which is responsible for filtering and transporting lymph throughout the body. The term "cervical" comes from the Latin word "cervix", which means neck.

Anatomy

Cervical lymph nodes are divided into several groups, including the anterior and posterior groups, and the superficial and deep groups. Each group is located in a different part of the neck and has a specific function in the lymphatic system.

Anterior Group

The anterior group of cervical lymph nodes is located along the front of the neck. These nodes are responsible for draining lymph from the pharynx, thyroid gland, and parts of the face and scalp.

Posterior Group

The posterior group of cervical lymph nodes is located along the back of the neck. These nodes drain lymph from the scalp and neck.

Superficial Group

The superficial group of cervical lymph nodes is located just beneath the skin. These nodes drain lymph from the skin and superficial tissues of the neck.

Deep Group

The deep group of cervical lymph nodes is located deeper within the neck. These nodes drain lymph from the throat, tonsils, and pharynx.

Clinical Significance

Enlargement of the cervical lymph nodes, known as lymphadenopathy, can be a sign of infection or disease. This can include infections of the throat or scalp, or more serious conditions such as cancer. In particular, cervical lymph nodes are often examined during the diagnosis and staging of head and neck cancer.
