![]() The superficial cervical lymph nodes are located close to the external and anterior jugular veins and collect lymph from the superficial surfaces of the anterior neck. The buccal lymph nodes collect lymph from the nose and cheek. When enlarged they can be felt or seen as raised lumps underneath the skin, most commonly in the neck, the armpits, or in the groin area. The submandibular lymph nodes are located below the mandible in the submandibular triangle and collect lymph from the face inferior to the eye and from the mouth. Lymph nodes are located throughout the body, including the neck, armpits, groin, around the gut. We can feel them if we press, but it should be obvious if they are swollen. The submandibular lymph nodes are the closest, but there is a set known as the retropharyngeal lymph nodes which are closer to the throat. The submental lymph nodes are located in the submental triangle superficial to the mylohyoid muscle and collect lymph from the chin and lower lip. Horses have two major sets of lymph nodes which can be felt under the jaw. The parotid lymph nodes are located superficial to the parotid gland and collect lymph from the lateral side of the face and scalp. The preauricular lymph nodes are located anterior to the auricle of the ear and collect lymph from the superficial areas of the face and temporal region. Specifically, they lie on the insertion of the SCM into the mastoid process, and they collect lymph from the posterior neck, upper ear and lateral scalp. The mastoid lymph nodes are also called retroauricular lymph nodes and they are located posterior to the ear. The occipital lymph nodes are located in the back of the head at the lateral border of the trapezius muscle and collect lymph from the occipital area of the scalp. There are 8 groups of superficial lymph nodes which extend from underneath the chin to the posterior aspect of the head and they are represented by the occipital, mastoid, preauricular, parotid, submental, submandibular, buccal and superficial cervical lymph nodes. So, the superficial lymph nodes receive lymph from the scalp, face and neck. on each side of the neck under the chin in the armpits around the groin Glands (known as lymph glands or lymph nodes) swell near an infection to help your body fight it. So, the lymphatics of the head and neck can be divided in two groups: a superficial group of nodes and a vertical group of deep lymph nodes. Location: Carotid sheath in the neck, near the internal jugular vein. What they are feeling for are the lymph nodes in our neck, which drain the head and neck, and become enlarged when there is an infection.Įnlarged lymph nodes can also indicate other clinical conditions such as cancers, so by understanding the anatomy of the lymph nodes in the neck and their drainage, this can help with clinical diagnosis! Thirdly, Deep cervical lymph nodes, that are divided into upper & lower sections. You may then develop swollen lymph glands in various parts of the body such as the neck, armpit and groins.Whenever we go to the doctor's office with what we think is a respiratory infection, they will often feel for ‘nodes’ in the neck. Viral infections such as flu (influenza), chickenpox or glandular fever (infectious mononucleosis) affect the whole body.Infections of the leg or genitals, or nappy rash, may cause lymph glands in the groin to swell.Skin infections of the arm may cause lymph glands in the armpit to swell.Scalp skin conditions or even head lice may cause the lymph glands at the back of the head to swell.Throat infections, tonsillitis, the common cold and tooth-related infections may cause lymph glands in the neck to swell. ![]() ![]() Examples of infections include the following: It can take a week or so for them gradually to go back to normal after the infection. If a surgeon removes a primary cancer, they often remove some of the nearby lymph nodes. For example, breast cancer cells may travel to lymph nodes in the armpit (axilla) or above the collar bone (clavicle). ![]() The lymph glands usually go back to their normal pea size when the infection is over. Sometimes cancer is found in lymph nodes that are near to where the cancer started. The lymph glands near to an infection swell quickly and become tender as the immune system 'fights off' infecting germs (bacteria, viruses, etc). ![]()
