The lymph nodes back of neck diagram is a helpful visual guide for understanding where the lymph nodes sit behind the head and along the back and sides of the neck. Now, these small, bean-shaped glands are part of the immune system and may swell when the body is fighting infection, inflammation, or other health conditions. Because the back of the neck contains several important lymph node groups, knowing their general location can help you recognize changes in your body and decide when medical advice may be needed Practical, not theoretical..
Introduction to the Lymph Nodes at the Back of the Neck
Lymph nodes are small structures that filter lymph fluid, a clear fluid that travels through the lymphatic system. Here's the thing — they help the body detect and respond to germs, damaged cells, and other unwanted substances. Lymph nodes are found throughout the body, but they are especially common in the neck, armpits, and groin Worth keeping that in mind..
The lymph nodes at the back of the neck are often called posterior cervical lymph nodes. They sit along the back of the neck and may also be near the base of the skull, behind the ears, and along the upper shoulder area. When these nodes enlarge, they may feel like small bumps, lumps, or tender areas under the skin.

Key Areas Shown in the Diagram
- Occipital lymph nodes: Located at the base of the skull, in the back of the head.
- Posterior auricular or mastoid nodes: Located behind the ears, over the bony area called the mastoid.
- Posterior cervical lymph nodes: Located along the back of the neck, often near the trapezius muscle.
- Deep cervical lymph nodes: Located deeper along the side of the neck, near major blood vessels and throat structures.
- Supraclavicular nodes: Located just above the collarbone; these are not exactly at the back of the neck but are often checked during neck exams.
What Each Lymph Node Area Drains
Each lymph node group drains fluid from a specific region of the body. This is why swelling in one area may point to a cause nearby.
Occipital Lymph Nodes
The occipital lymph nodes are located at the base of the skull. On the flip side, they drain lymph from the scalp, especially the back of the head. Swelling in this area may occur after scalp irritation, dandruff, insect bites, fungal infections, cuts, or certain viral infections That alone is useful..
