Superficial cervical lymph nodes

The superficial cervical lymph nodes are a group of lymph nodes located in the neck. They are part of the lymphatic system, which plays a crucial role in the body's immune response by filtering lymph fluid and trapping pathogens.

Anatomy

The superficial cervical lymph nodes are situated along the external jugular vein and lie superficial to the sternocleidomastoid muscle. They are responsible for draining lymph from the superficial tissues of the head and neck, including the scalp, face, and superficial ear regions.

Function

These lymph nodes filter lymphatic fluid, removing bacteria, viruses, and other foreign particles. They also play a role in the immune response by housing lymphocytes, which are white blood cells that help fight infection.

Clinical significance

Enlargement of the superficial cervical lymph nodes can occur due to infections, such as upper respiratory tract infections, or more serious conditions like lymphoma or metastatic cancer. Palpation of these nodes is a common part of a physical examination when assessing for signs of infection or malignancy.
