Jugular Lymphatic Trunk

	Jugular Lymphatic Trunk 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 ....

	Superior 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. Most of these lymph nodes are situated deep to the sternocleidomastoid muscle The sternocleidomastoid muscle is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. The sternocleidomastoid is innervated by the access ..., though some are not. Some are situated anterior and some posterior to the internal jugular vein. They are also situated adjacent to the accessory nerve (CN XI). Jugulodigastric group Superior deep cervical lymph nodes situated in a triangular region bounded by the posterior belly of the digastric muscle, the facial vein, and the internal jugular vein form a subgroup - the jugulodigastric group. The group consists o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Inferior Deep Cervical Lymph Nodes The inferior deep cervical lymph nodes extend beyond the posterior margin of the sternocleidomastoid muscle into the subclavian triangle, where they are closely related to the brachial plexus and subclavian vein The subclavian vein is a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart. The left subclavian vein plays a key role in the absorption .... References Lymphatics of the head and neck {{Portal bar, Anatomy ...

picture info	Lymphatic Vessel The lymphatic vessels (or lymph vessels or lymphatics) are thin-walled vessels (tubes), structured like blood vessels, that carry lymph. As part of the lymphatic system, lymph vessels are complementary to the cardiovascular system. Lymph vessels are lined by endothelial cells, and have a thin layer of smooth muscle, and adventitia that binds the lymph vessels to the surrounding tissue. Lymph vessels are devoted to the propulsion of the lymph from the lymph capillaries, which are mainly concerned with the absorption of interstitial fluid from the tissues. Lymph capillaries are slightly bigger than their counterpart capillaries of the vascular system. Lymph vessels that carry lymph to a lymph node are called afferent lymph vessels, and those that carry it from a lymph node are called efferent lymph vessels, from where the lymph may travel to another lymph node, may be returned to a vein, or may travel to a larger lymph duct. Lymph ducts drain the lymph into one of the subclavia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Internal Jugular Vein The internal jugular vein is a paired jugular vein that collects blood from the brain and the superficial parts of the face and neck. This vein runs in the carotid sheath with the common carotid artery and vagus nerve. It begins in the posterior compartment of the jugular foramen, at the base of the skull. It is somewhat dilated at its origin, which is called the ''superior bulb''. This vein also has a common trunk into which drains the anterior branch of the retromandibular vein, the facial vein, and the lingual vein. It runs down the side of the neck in a vertical direction, being at one end lateral to the internal carotid artery, and then lateral to the common carotid artery, and at the root of the neck, it unites with the subclavian vein to form the brachiocephalic vein (innominate vein); a little above its termination is a second dilation, the ''inferior bulb''. Above, it lies upon the rectus capitis lateralis, behind the internal carotid artery and the nerves passing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Subclavian Veins The subclavian vein is a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart. The left subclavian vein plays a key role in the absorption of lipids, by allowing products that have been carried by lymph in the thoracic duct to enter the bloodstream. The diameter of the subclavian veins is approximately 1–2 cm, depending on the individual. Structure Each subclavian vein is a continuation of the axillary vein and runs from the outer border of the first rib to the medial border of anterior scalene muscle. From here it joins with the internal jugular vein to form the brachiocephalic vein (also known as "innominate vein"). The angle of union is termed the venous angle. The subclavian vein follows the subclavian artery and is separated from the subclavian artery by the insertion of anterior scalene. Thus, the subclavian vein lies anterior to the anterior scalene while the su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Venous Angle The venous angle, also known as Pirogoff's angle and in Latin as angulus venosus, is the junction where the internal jugular (Latin: ''v. jugularis interna'') and subclavian (Latin: ''v. subclavia'') veins at each side of the neck merge to form the corresponding brachiocephalic vein.http://medical-dictionary.thefreedictionary.com/venous+angle The Free Dictionary The left venous angle receives lymph from the thoracic duct (Latin: ''ductus thoracicus''). The right venous angle receives lymph from the right lymphatic trunk (Latin: ''truncus lymphaticus''). The (right) lymphatic trunk is only about 1 cm long and conveys lymph from the right side of the thorax (including parts of the liver) as well as the right arm and parts of the head and neck. The eponym is a reference to Nikolay Pirogov Nikolay Ivanovich Pirogov (Russian: Никола́й Ива́нович Пирого́в; — ) was a Russian scientist, medical doctor, pedagogue, public figure, and corresponding member of ...

picture info	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 lymphatic duct. The thoracic duct carries chyle, a liquid containing both lymph and emulsified fats, rather than pure lymph. It also collects most of the lymph in the body other than from the right thorax, arm, head, and neck (which are drained by the right lymphatic duct). The thoracic duct usually starts from the level of the twelfth thoracic vertebra (T12) and extends to the root of the neck. It drains into the systemic (blood) circulation at the junction of the left subclavian and internal jugular veins, at the commencement of the brachiocephalic vein. When the duct ruptures, the resulting flood of liquid into the pleural cavity is known as chylothorax. Structure In adults, the thoracic duct is typically 38–45 cm in length an ...
