Submental lymph nodes. Superficial lymph glands and lymphatic vessels of head and neck. (Buccinator glands labeled at center right.) The submental lymph nodes (or suprahyoid lymph nodes[citation needed]) are 2-3 lymph nodes [1] situated in the submental triangle, [1] between the anterior bellies of the digastric muscle and the hyoid bone. [2]
The most common causes of enlargement of the submandibular lymph nodes are infections of the head, neck, ears, eyes, nasal sinuses, pharynx, and scalp. [1] The lymph glands may be affected by metastatic spread of cancers of the oral cavity, anterior portion of the nasal cavity, soft tissues of the mid-face, and submandibular salivary gland. [1]
The submental space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space located between the mylohyoid muscle superiorly, the platysma muscle inferiorly, [1] under the chin in the midline. The space coincides with the anatomic region termed the submental triangle, part of the ...
The submandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space, and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle. [1] The space corresponds to the anatomic ...
The most distinctive sign of bubonic plague is extreme swelling of one or more lymph nodes that bulge out of the skin as "buboes." The buboes often become necrotic and may even rupture. [5] Infectious mononucleosis is an acute viral infection usually caused by Epstein-Barr virus and may be characterized by a marked enlargement of the cervical ...
Surgery or treatment for prostate, colon and testicular cancers may result in secondary lymphedema, particularly when lymph nodes have been removed or damaged. [ medical citation needed ] The onset of secondary lymphedema in patients who have had cancer surgery has also been linked to aircraft flight (likely due to decreased cabin pressure or ...
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
Buccinator lymph node. Superficial lymph glands and lymphatic vessels of head and neck. (Buccinator glands labeled at center right.) The buccinator lymph node or nodes are one or more lymph nodes placed on the buccinator opposite the angle of the mouth.
