Where Are Lymph Nodes In The Neck Diagram?

Neck lymph nodes sit under the jaw, along the neck sides, behind the ear, and above the collarbone in small chains.

If you typed “where are lymph nodes in the neck diagram?” you’re probably after one thing — a clear map you can match to your own neck. Lymph nodes are small filters that sit along lymph vessels, and they tend to gather in groups near familiar landmarks.

This guide uses the same surface landmarks clinicians use during a neck exam — the jawline, the big side‑neck muscle, and the collarbone. You’ll get a simple diagram-style layout, a plain-language description of each node area, and a safe way to check what you’re feeling at home.

Neck Lymph Node Map On A Simple Diagram

On most neck diagrams, you’ll see “chains” of nodes running like beads. They sit in shallow layers you can sometimes feel, plus deeper layers you can’t. The names change a bit by textbook, yet the map stays consistent when you anchor it to bones and muscles.

Use this quick layout first, then the next sections will pin each group to a spot you can find in a mirror.

Front view (simple map)
  Under chin – Submental
  Under jaw – Submandibular
  Front neck – Anterior cervical chain
  Side neck – Deep cervical chain (along the big side muscle)
  Above collar – Supraclavicular
Back/side view
  Behind ear – Mastoid (post‑auricular)
  Base of skull – Occipital
  Back neck – Posterior cervical chain

Check Under The Chin — Submental nodes sit in the soft pocket between the chin and the top of the throat.
Check Under The Jawline — Submandibular nodes tuck under the curve of the jaw, often noticed with dental or throat irritation.
Trace The Front Neck Line — Anterior cervical nodes run down the front/side border of the neck, near the throat and voice box area.
Follow The Side Neck Muscle — Deep cervical nodes track along the sternocleidomastoid, the rope-like muscle that pops when you turn your head.
Feel Behind The Ear — Mastoid nodes sit just behind the ear, near the bony bump.
Feel The Base Of The Skull — Occipital nodes sit where the head meets the neck, under the hairline.
Scan Above The Collarbone — Supraclavicular nodes sit in the hollow just above the clavicle and need prompt medical attention when enlarged.

Neck Lymph Nodes Diagram Locations By Chain

Many diagrams label node “levels” or “chains.” For at-home self-location, it’s easier to group them by the surface line you can touch. Think in three strips — under the jaw, along the side neck, and the collarbone area.

A widely used anatomy summary from Cleveland Clinic lists clusters behind the ear and at the skull base, plus cervical and supraclavicular clusters along the sides of the neck. You can see that overview on their lymph node locations page.

Node Group	Where You Match It On Your Neck	Area It Often Drains
Submental	Midline, under the chin	Lower lip, front mouth, chin skin
Submandibular	Under the jaw curve	Teeth, gums, tongue sides, tonsil area
Anterior cervical	Front/side neck near throat	Throat, tonsils, voice box region
Posterior cervical	Back/side of neck	Scalp, skin on neck, upper airway
Supraclavicular	Hollow above the collarbone	Deep chest or abdomen routes

The “drainage” column is a shortcut, not a diagnosis tool. Skin irritation on the scalp can swell nodes behind the ear.

How To Use A Neck Diagram With Your Own Landmarks

A diagram is only useful if you can line it up with your own anatomy. Don’t press hard.

Wash your hands and use the pads of two fingers, not the tips. If your skin is dry, a small amount of lotion reduces friction so you don’t pinch skin.

Set Your Head Position — Face a mirror, relax your shoulders, and turn your head slightly to one side.
Find The Side Neck Muscle — Place fingers below your ear and slide down to feel the firm band of the sternocleidomastoid.
Use Light Circular Touch — Roll your fingertips in small circles over soft tissue, not over the hard edge of bone.
Compare Left And Right — Check the same spot on both sides so you notice symmetry, not tiny differences.
Move In A Simple Route — Under chin, under jaw, down the side neck, then the hollow above the collarbone.

If you’re checking because you feel one lump, start with that spot, then do a short scan around it. If you’re checking due to a cold, skip daily checks.

What Normal Neck Lymph Nodes Feel Like

Many people can’t feel any nodes at all, and that can still be normal. When you do feel them, they’re often small, smooth, and move a bit under the skin. Some feel like a lentil or small bean. In kids and teens, small “shotty” nodes (pea-like, in a row) can linger after a recent infection.

Tenderness often lines up with an infection or irritation nearby. Pain alone doesn’t sort “safe” from “not safe,” but it does tell you not to keep pressing on it.

If a lump is rock-hard, fixed in place, or paired with trouble swallowing or breathing, treat it as urgent. The same goes for a node that keeps enlarging week after week.

Common Reasons Neck Nodes Swell

In many cases the cause is a viral illness, like a cold. Bacterial throat or dental infections can also do it. Mayo Clinic lists common triggers and also lists reasons to seek care on its swollen lymph nodes symptoms page.

Throat, Ear, And Sinus Illness

When your throat is sore or your tonsils are inflamed, nodes under the jaw and down the front/side of the neck can swell. Ear infections can swell nodes near the ear or under the jaw. Sinus congestion can do the same, paired with facial pressure.

If you have a runny nose and cough and the nodes feel tender, the pattern often fits a passing virus.

Dental And Gum Sources

A bad tooth, gum infection, or a sore in the mouth can trigger submandibular nodes. Pain with chewing, tooth sensitivity, bad taste, or gum swelling can be a clue. Dental issues can linger, so don’t wait weeks if mouth pain is growing.

If swelling is one-sided, note mouth sores, tooth pain, or gum bleeding on that side. A dentist can spot an abscess or a cracked tooth that isn’t obvious.

Skin And Scalp Irritation

Nodes behind the ear or at the base of the skull can react to scalp issues. Think inflamed pimples, eczema flares, infected cuts, or lice. Treating the skin source often settles the node over time.

Part your hair and scan the scalp for scabs, redness, or tender spots. If there’s a cut or rash, keep it clean and watch for spreading redness.

Less Common Causes That Need A Clinician

Some node swelling isn’t tied to a clear infection. Autoimmune conditions, certain medicines, and cancers can cause enlarged nodes. You don’t need to jump to the worst story, yet you do need a plan if swelling has no clear trigger or doesn’t ease.

If swelling has no clear trigger, write down new medicines, rashes, joint pain, and recent travel. Bring that note to your visit so the exam starts with good context.

When Neck Lumps Need Medical Care

Use a simple time-and-pattern check. If a node shows up with a cold and then shrinks as you improve, that’s a common track. If it sticks around, grows, or comes with whole‑body symptoms, get it checked.

Book A Visit Soon — A node lasts 2–4 weeks, or keeps getting larger over that span.
Go In Promptly — The lump feels hard, doesn’t move, or sits above the collarbone.
Get Same‑Day Care — You have trouble swallowing, breathing, or opening your mouth fully.
Don’t Wait It Out — Fever, night sweats, or weight loss show up with the swelling.
Seek Care For Kids Too — A child has a painful, red, hot neck lump or looks ill.

If you’ve been pressing a spot daily, stop for a week and re-check. Irritated tissue can stay sore even after the trigger fades.

What A Clinician May Do With A Neck Node Finding

Most visits start with history and a hands-on exam. Expect questions about recent colds, sore throat, dental pain, travel, pets, new medicines, and how long the lump has been there.

Then the clinician checks the mouth, throat, ears, and skin, and feels for nodes on both sides. If the pattern fits an infection, the plan may be watchful waiting or treatment for the source. If the pattern is unclear, testing can follow.

Order Basic Blood Work — A blood count and inflammation markers can hint at infection or other causes.
Use Imaging When Needed — Ultrasound can measure a node and show its shape. CT or MRI can map deeper nodes.
Sample The Node If Indicated — A needle sample or biopsy checks cells when the exam raises concern.
Treat The Trigger — Dental care, antibiotics for a proven bacterial infection, or other targeted care may follow.

If you’re worried you’ll forget details, jot down the start date, size changes, pain level, and any paired symptoms before the visit. That short log makes the exam more efficient.

Frequently Asked Questions

Can you feel deep cervical lymph nodes through the skin?

Most deep cervical nodes sit under muscle and are hard to feel in a normal neck. People often feel the sternocleidomastoid muscle and mistake it for a node. If a deep node is big enough to feel, it’s worth a clinical exam, since that’s not the usual baseline.

Why do nodes hurt after I keep checking them?

Repeated pressing can bruise soft tissue and irritate the node capsule, which can add soreness that wasn’t there at first. Give the area a break for a week, then re-check with a light touch. If pain is sharp, skin is red, or fever is present, seek care sooner.

Is a “pea-size” node in the neck normal?

Small, movable nodes can be normal, especially after a cold or in children. Size alone can’t rule things in or out. Track the trend. Shrinking over days to weeks is reassuring. A lump that keeps enlarging, feels fixed, or sits above the collarbone needs evaluation.

What’s the fastest way to tell a lymph node from a salivary gland?

Salivary glands are larger and sit in predictable blocks, like the parotid near the cheek and the submandibular gland under the jaw. A node is often smaller and more “bead-like.” If swelling changes with meals, or dry mouth is present, a clinician or dentist can sort the cause.

How often should I re-check a swollen neck node?

If you’re sick, wait until you’re feeling better, then re-check once after several days. Daily checks can keep the area tender. If the node is still there after a couple of weeks, is growing, or comes with fever, night sweats, weight loss, or breathing trouble, get medical care.

Wrapping It Up – Where Are Lymph Nodes In The Neck Diagram?

Most neck diagrams are showing the same map — clusters under the chin and jaw, chains down the side neck, and a small set near the collarbone, plus nodes behind the ear and under the hairline. Once you line the picture up with your jaw and the big side-neck muscle, the labels start to make sense.

If you came here with a diagram in mind, use the map to orient yourself at home first, then use a light, gentle touch and a simple route if you’re checking a lump. If swelling has no clear trigger, lasts weeks, keeps growing, or sits above the collarbone, set up a medical visit so you can get a clear answer.
