Parotid Lymph Nodes
Parotid lymph nodes are lymph nodes found near the parotid gland in the immune system. More specifically, it can refer to: * deep parotid lymph nodes * superficial parotid lymph nodes The superficial parotid lymph nodes are a group of lymph nodes anterior to the ear. Their ''afferent'' vessels drain the root of the nose, the eyelids, the frontotemporal region, the external acoustic meatus and the tympanic cavity, possibly also ... 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".

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).

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.

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 The anterior triangle is a region of the neck. Structure The triangle is inverted with its apex inferior to its base which is under the chin. Investing fascia covers the roof of the triangle while visceral fascia covers the floor. Anatomy Mu ....

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 right ....

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").

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 mandibular ramus, and secretes serous saliva through the parotid duct into the mouth, to facilitate mastication and swallowing and to begin the digestion of starches. There are also two other types of salivary glands; they are submandibular and sublingual glands. Sometimes accessory parotid glands are found close to the main parotid glands. Etymology The word ''parotid'' literally means "beside the ear". From Greek παρωτίς (stem παρωτιδ-) : (gland) behind the ear < παρά - pará : in front, and οὖς - ous (stem ὠτ-, ōt-) : ear.

Deep Parotid Lymph Nodes
The deep parotid lymph nodes are lymph nodes found below the parotid gland. The ''afferents'' of the subparotid glands drain the nasal part of the pharynx The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the oesophagus and trachea (the tubes going down to the stomach and the lungs). It is found in vertebrates and invertebrates, though its struc ... and the posterior parts of the nasal cavities. Their ''efferents'' pass to the superior deep cervical glands.
