The right and left[ citation needed ]paratracheal lymph nodes (or paratracheal chains[ citation needed ]) are lymph nodes in the neck [1] situated lateral to the trachea and esophagus alongside the recurrent laryngeal nerve. They drain to the deep cervical lymph nodes. [2]
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.
The submandibular triangle corresponds to the region of the neck immediately beneath the body of the mandible.
The tracheobronchial lymph nodes are lymph nodes that are located around the division of trachea and main bronchi.
Cervical lymph nodes are lymph nodes found in the neck. Of the 800 lymph nodes in the human body, 300 are in the neck. Cervical lymph nodes are subject to a number of different pathological conditions including tumours, infection and inflammation.
The occipital lymph nodes, one to three in number, are located on the back of the head close to the margin of the trapezius and resting on the insertion of the semispinalis capitis.
The mastoid lymph nodes 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.
The deep cervical lymph nodes are a group of cervical lymph nodes in the neck that form a chain along the internal jugular vein within the carotid sheath.
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.
The inferior deep cervical lymph nodes are one of the two groups of the deep cervical lymph nodes.
The superior deep cervical lymph nodes are the deep cervical lymph nodes that are situated adjacent to the superior portion of the internal jugular vein. They drain either to the inferior deep cervical lymph nodes or into the jugular trunk.
The submental lymph nodes are 2-3 lymph nodes situated in the submental triangle, between the anterior bellies of the digastric muscle and the hyoid bone.
The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck.
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.
The submandibular lymph nodes, are some 3-6 lymph nodes situated at the inferior border of the ramus of mandible.
The deep parotid lymph nodes are lymph nodes found below the parotid gland.
Parotid lymph nodes are lymph nodes found near the parotid gland in the immune system.
The superficial lateral cervical lymph nodes are found along the course of the external jugular vein, between the inferior aspect of the parotid gland and the supraclavicular nodes. The nodes are intercalated along the course of the vessels draining the parotid nodes and the infraauricular nodes. These nodes drain into the supraclavicular nodes, and on to the jugular trunk, followed by the thoracic duct on the left or the right lymphatic duct.
The anterior cervical lymph nodes are a group of nodes found on the anterior part of the neck, in front of the sternocleidomastoid muscle. These can be grouped into a deep and superficial group.
The pretracheal lymph nodes are lymph nodes located anterior to the trachea in the neck.
The lateral cervical lymph nodes are a group of lymph nodes found in the lateral side of the neck.
