Inferior deep cervical lymph nodes

Inferior deep cervical lymph nodes

Lymph nodes of the head and neck. (Inferior deep cervical lymph nodes are labeled at the bottom right.)
Latin	nodi lymphoidei cervicales profundi inferiores
System	Lymphatic system

The inferior deep 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 inferior deep cervical lymph nodes are situated along the lower part of the internal jugular vein, beneath the sternocleidomastoid muscle. They are part of the deep cervical lymph node group, which is divided into superior and inferior nodes based on their location relative to the omohyoid muscle.

Function

These lymph nodes are responsible for draining lymph from the head and neck region, including the scalp, face, nasal cavity, pharynx, and parts of the ear. They receive lymph from the superior deep cervical lymph nodes and other regional nodes, and they drain into the jugular lymphatic trunk, which ultimately empties into the thoracic duct or the right lymphatic duct.

Clinical significance

The inferior deep cervical lymph nodes can become enlarged due to infections, inflammatory conditions, or malignancies. Enlargement of these nodes can be a sign of conditions such as lymphoma, metastatic cancer, or infectious mononucleosis. Palpation of these nodes is an important part of the physical examination of the neck.
