Buccinator Lymph Node
The buccinator lymph node or nodes are one or more lymph nodes placed on the Buccinator opposite the angle of the mouth In animal anatomy, the mouth, also known as the oral cavity, or in Latin cavum oris, is the opening through which many animals take in food and issue vocal sounds. It is also the cavity lying at the upper end of the alimentary canal, bounded on t .... References External links * () Lymphatics of the head and neck {{Portal bar, Anatomy ...

Submental Lymph Nodes
The submental glands (or suprahyoid) are situated between the anterior bellies of the digastric muscle and the hyoid bone. Their '' afferents'' drain the central portions of the lower lip and floor of the mouth and the apex of the tongue. Their '' efferents'' pass partly to the submandibular lymph nodes and partly to a gland of the deep cervical group situated on the internal jugular vein at the level of the cricoid cartilage.

Submandibular Lymph Nodes
The submandibular lymph nodes (submaxillary glands in older texts), three to six in number, are lymph nodes beneath the body of the mandible in the submandibular triangle, and rest on the superficial surface of the submandibular gland. One gland, the ''middle gland of Stahr'', which lies on the facial artery as it turns over the mandible, is the most constant of the series; small lymph glands are sometimes found on the deep surface of the submandibular gland. The ''afferents'' of the submandibular glands drain the medial canthus, the cheek, the side of the nose, the upper lip, the lateral part of the lower lip, the gums, and the anterior part of the margin of the tongue. Efferent lymph vessels from the facial and submental lymph nodes also enter the submandibular glands. Their efferent vessels pass to the superior deep cervical lymph nodes.

Supraclavicular Lymph Nodes
Supraclavicular lymph nodes are lymph nodes found above the clavicle, that can be felt in the supraclavicular fossa. The supraclavicular lymph nodes on the left side are called Virchow's nodes.page 400 in: It leads to an appreciable mass that can be recognized clinically, called Troisier sign. Structure A Virchow's node is a left-sided supraclavicular lymph node.Clinical significance 
Malignancies of the internal organs can reach an advanced stage before giving symptoms.

Retropharyngeal Lymph Nodes
The retropharyngeal lymph nodes, from one to three in number, lie in the buccopharyngeal fascia, behind the upper part of the pharynx and in front of the arch of the atlas, being separated, however, from the latter by the Longus capitis. Their ''afferents'' drain the nasal cavities, the nasal part of the pharynx, and the auditory tubes. Their ''efferents'' pass to the superior deep cervical lymph nodes. They are in the retropharyngeal space. They frequently disappear by age 4-5. (This is why retropharyngeal abscess Retropharyngeal abscess (RPA) is an abscess located in the tissues in the back of the throat behind the posterior pharyngeal wall (the retropharyngeal space).

Superficial Cervical Lymph Nodes
The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck. Some sources state simply that they lie along the external jugular vein, while other sources state that they are only adjacent to the external jugular vein in the posterior triangle, and they are adjacent to the anterior jugular vein in the anterior triangle. They can be broken down into: * superficial anterior cervical lymph nodes The superficial anterior cervical lymph nodes are found in proximity to the anterior jugular vein The anterior jugular vein is a vein in the neck.

Jugular Lymph Nodes
The jugular trunk is a lymphatic vessel in the neck. It is formed by vessels that emerge from the superior deep cervical lymph nodes and unite to efferents of the inferior deep cervical lymph nodes. On the right side, this trunk ends in the junction of the internal jugular and subclavian veins, called the venous angle. On the left side it joins the thoracic duct In human anatomy, the thoracic duct is the larger of the two lymph ducts of the lymphatic system. It is also known as the ''left lymphatic duct'', ''alimentary duct'', ''chyliferous duct'', and ''Van Hoorne's canal''. The other duct is the righ ....

Parotid Lymph Nodes
Parotid lymph nodes are lymph nodes found near the parotid gland The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears. They are the largest of the salivary glands. Each parotid is wrapped around the m ... in the immune system. More specifically, it can refer to: * deep parotid lymph nodes * superficial parotid lymph nodes Etymology The word ''parotid'' comes from the grc, πᾰρᾰ́ (, "beside; next to, near, from; against, contrary to") + (, from , "ear") + ''-id'', thus "next to, near the ear".

Retroauricular Lymph Nodes
The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle. Their mastoid lymph nodes receives lymph from the posterior part of the temporoparietal region, the upper part of the cranial surface of the visible ear and the back of the ear canal. The lymph then passes to the superior deep cervical glands. Etymology The word ''mastoid'' comes from the grc, μάσταξ (, "mouth, jaws, that with which one chews").

Lymph Nodes
A lymph node, or lymph gland, is a kidney-shaped organ of the lymphatic system and the adaptive immune system. A large number of lymph nodes are linked throughout the body by the lymphatic vessels. They are major sites of lymphocytes that include B and T cells. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles including cancer cells, but have no detoxification function. In the lymphatic system a lymph node is a secondary lymphoid organ. A lymph node is enclosed in a fibrous capsule and is made up of an outer cortex and an inner medulla. Lymph nodes become inflamed or enlarged in various diseases, which may range from trivial throat infections to life-threatening cancers. The condition of lymph nodes is very important in cancer staging, which decides the treatment to be used and determines the prognosis. Lymphadenopathy refers to glands that are enlarged or swollen. When inflamed or enlarged, lymph nodes can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buccinator
The buccinator () is a thin quadrilateral muscle occupying the interval between the maxilla and the mandible at the side of the face. It forms the anterior part of the cheek or the lateral wall of the oral cavity.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, page 91 Structure It arises from the outer surfaces of the alveolar processes of the maxilla and mandible, corresponding to the three pairs of molar teeth and in the mandible, it is attached upon the buccinator crest posterior to the third molar; and behind, from the anterior border of the pterygomandibular raphe which separates it from the constrictor pharyngis superior. The fibers converge toward the angle of the mouth, where the central fibers intersect each other, those from below being continuous with the upper segment of the orbicularis oris, and those from above with the lower segment; the upper and lower fibers are continued forward into the corresponding lip without decussati ...
