Paratracheal Lymph Nodes
The right and left paratracheal lymph nodes (or paratracheal chains) are groups of lymph nodes located in the throat In vertebrate anatomy, the throat is the front part of the neck, internally positioned in front of the vertebrae. It contains the pharynx and larynx. An important section of it is the epiglottis, separating the esophagus from the trachea (windpipe ....

Bronchomediastinal Lymph Trunks
The tracheobronchial lymph nodes are lymph nodes that are located around the division of trachea and main bronchi. Structure These lymph nodes form four main groups including paratracheal, tracheobronchial, bronchopulmonary and pulmonary nodes. # ''Paratracheal nodes'' are located on either side of the trachea. # ''Tracheobronchial nodes'' can be divided into three nodes including left and right superior tracheobronchial nodes, and the inferior trachiobronchial node. The two superior tracheobronchial nodes are located on either side of trachea just before its bifurcation. The inferior tracheobronchial node is located just below the bifurcation in the angle between the two bronchi. # ''Bronchopulmonary nodes'' situate in the hilum of each lung. # ''Pulmonary nodes'' are embedded the lung substance on the larger branches of the bronchi. The ''afferents'' of the tracheobronchial glands drain the lungs and bronchi, the thoracic part of the trachea and the heart; some o ...

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 be fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Throat
In vertebrate anatomy, the throat is the front part of the neck, internally positioned in front of the vertebrae. It contains the pharynx and larynx. An important section of it is the epiglottis, separating the esophagus from the trachea (windpipe), preventing food and drinks being inhaled into the lungs. The throat contains various blood vessels, pharyngeal muscles, the nasopharyngeal tonsil, the tonsils, the palatine uvula, the trachea, the esophagus, and the vocal cords. Mammal throats consist of two bones, the hyoid bone and the clavicle. The "throat" is sometimes thought to be synonymous for the fauces. It works with the mouth, ears and nose, as well as a number of other parts of the body. Its pharynx is connected to the mouth, allowing speech to occur, and food and liquid to pass down the throat. It is joined to the nose by the nasopharynx at the top of the throat, and to the ear by its Eustachian tube. The throat's trachea carries inhaled air to the bronchi of the lungs. ...
