In fact, lymph nodes are not actually glands. They are small bundles of white blood cells that are present in multiple areas throughout our body. One of the ways the body's immune system responds to infections and inflammation is to greatly increase the number of white cells in the lymph nodes causing them to swell.
The parotid glands, the largest pair of salivary glands, lie just behind the angle of the jaw, below and in front of the ears. The sublingual glands lie under the side of the tongue. The submandibular glands lie under the side of the jaw.
Swollen lymph nodes will feel like soft, round bumps, and they may be the size of a pea or a grape. They might be tender to the touch, which indicates inflammation. In some cases, the lymph nodes will also look larger than usual. Lymph nodes appear in parallel on both sides of the body.Jan 7, 2019
Swollen lymph nodes on the side of the neck or under jaw: Swollen lymph nodes on the side of the neck or under the jaw are the most common. They may represent an infection around that area, such as a tooth infection or abscess, throat infection, viral illness, or upper respiratory infection.Feb 1, 2018
Your posterior cervical lymph nodes are located near the back of your neck. Several things can cause a swollen posterior cervical lymph node, but the most common cause is a viral infection, such as a cold or the flu.May 1, 2018

Swollen lymph nodes usually occur as a result of infection from bacteria or viruses. Rarely, swollen lymph nodes are caused by cancer. Your lymph nodes, also called lymph glands, play a vital role in your body's ability to fight off infections.
Those lumps probably feel soft and tender to the touch — and may even hurt a little. Swollen lymph nodes (or what doctors call lymphadenopathy) are common and are actually a good thing. The swelling in these pea- or bean-sized lymph nodes are one of your body's natural reactions to illness or infection.Oct 23, 2019
The suprasternal notch, also known as the fossa jugularis sternalis, or jugular notch, or Plender gap is a large, visible dip in between the neck in humans, between the clavicles, and above the manubrium of the sternum.
Viral infections such as mumps, flu, and others can cause swelling of the salivary glands. Swelling happens in parotid glands on both sides of the face, giving the appearance of "chipmunk cheeks." Salivary gland swelling is commonly associated with mumps, happening in about 30% to 40% of mumps infections.Jan 24, 2020
The quadrangular area is on the side of the neck and is bounded superiorly by the lower border of the body of the mandible and the mastoid process, inferiorly by the clavicle, anteriorly by a midline in front of the neck, and posteriorly by the trapezius muscle.Nov 30, 2017
Lymph nodes often swell in one location when a problem such as an injury, infection, or tumor develops in or near the lymph node. Which lymph nodes are swollen can help identify the problem. The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat.
Lymph nodes exist throughout the body, including in the back area of the skull, which is called the occipital region. Doctors refer to nodes in this area as occipital lymph nodes. Most of the time, people may not notice their occipital lymph nodes.
The lymph nodes are found from the head to around the knee area. The spleen, which is located on the left side of the body just above the kidney, is the largest lymphatic organ, according to the U.S. National Library of Medicine (NLM).Feb 20, 2018
Usually lymph nodes are not enlarged and thus not able to be felt, but if you have previously had an infection (such as tonsillitis) you may have noticed and felt lymph node becoming enlarged, painful and tender.
Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. There are hundreds of lymph nodes throughout the body.Mar 2, 2021
Neck (there is a chain of lymph nodes on either side of the front of the neck, both sides of the neck, and down each side of the back of the neck) Under the jaw and chin. Behind the ears. On the back of the head.
Rarely do they signal any problem. Over age 40, persistent large lymph nodes have a 4 percent chance of cancer.Oct 7, 2014
The Causes of Swollen Lymph NodesFor the most part, your lymph nodes tend to swell as a standard response to infection. They may also swell due to stress.
How to Check Lymph Nodes in the Head and Neck
- With your fingertips, in a gentle circular motion feel the lymph nodes shown.
- Start with the nodes in front of the ear (1) then follow in order finishing just above the collar bone (10)
- Always check your nodes in this order.
- Check both sides for comparison.
Lymphadenopathy is classically described as a node larger than 1 cm, although this varies by lymphatic region. Palpable supraclavicular, iliac, or popliteal nodes of any size and epitrochlear nodes larger than 5 mm are considered abnormal.Dec 1, 2002
Level III nodes are located between the hyoid superiorly and a horizontal plane defined by the inferior border of the cricoid cartilage. The sternohyoid muscle marks the anterior limit of level III, and the posterior border of the sternocleidomastoid muscle is the posterior border.
Lymph nodes in the neck are grouped into levels I-V, corresponding with the submandibular and submental nodes (level I); upper, middle, and lower jugular nodes (levels II, III, IV); and posterior triangle nodes (level V). Refer to the following image. The 6 levels of the neck with sublevels.Aug 13, 2021
Level VII lymph nodes are defined as lymph nodes in the anterior superior mediastinum and the tracheoesophageal grooves, extending from the suprasternal notch to the innominate artery [10].May 6, 2011
Level VIb encompasses inferior laryngeal nodes. Within the traditional limits of level VI, all lymph nodes lying between the inferior border of the hyoid bone and the inferior border of the cricoid cartilage belong to level VIa.
Level II nodes are internal jugular nodes above the level of the hyoid bone. Level III nodes are internal jugular nodes located between the hyoid bone and cricoid cartilage landmarks. Figure 5. Contrast-enhanced CT shows a right enlarged level IV lymph node (white arrow) which mimics a vessel.
​There are two sublevels: level Ia (submental nodes): anteromedial between the anterior bellies of both digastric muscles. level Ib (submandibular nodes): posterolateral to the anterior belly of the digastric muscles.Mar 23, 2021
If a person has no signs of an infection, a swollen lymph node might be a sign that the body has successfully fought off an infection. It is safe to wait for about 2 weeks to see if the swelling decreases. If the swelling does not go away, or if the lymph node is hard or larger than 1.5 cm in diameter, see a doctor.
Home remedies to treat symptoms of swollen lymph nodes include:
- taking over-the-counter pain relievers, like acetaminophen or ibuprofen.
- applying a warm, moist compress on the affected area.
- drinking lots of fluids, like water and fresh juices.
- rest to help the body recover from illness.
