Facial lymph nodes. The lymphatics of the face. The facial lymph nodes comprise three groups: (c) supramandibular, on the outer surface of the mandible, in front of the masseter and in contact with the external maxillary artery and anterior facial vein. Their afferent vessels drain the eyelids, the conjunctiva, and the skin and mucous membrane ...
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
In the lymphatic system, a lymph node is a secondary lymphoid organ. [4] Diagram of a lymph node showing lymphocytes. The primary function of lymph nodes is the filtering of lymph to identify and fight infection. In order to do this, lymph nodes contain lymphocytes, a type of white blood cell, which includes B cells and T cells.
The most common causes of enlargement of the submandibular lymph nodes are infections of the head, neck, ears, eyes, nasal sinuses, pharynx, and scalp. [ 1 ] The lymph glands may be affected by metastatic spread of cancers of the oral cavity, anterior portion of the nasal cavity, soft tissues of the mid-face, and submandibular salivary gland.
The superficial inguinal lymph nodes are the inguinal lymph nodes that form a chain immediately inferior to the inguinal ligament. They lie deep to the fascia of Camper that overlies the femoral vessels at the medial aspect of the thigh. They are bounded superiorly by the inguinal ligament in the femoral triangle, laterally by the border of the ...
v. t. e. Manual lymphatic drainage (MLD) is a type of manual manipulation of the skin, not to be confused with massage, based on the hypothesis that it will encourage the natural drainage of the lymph, which carries waste products away from the tissues back toward the heart. The lymph system depends on intrinsic contractions of the smooth ...
Axillary lymph nodes. The axillary lymph nodes or armpit lymph nodes are lymph nodes in the human armpit. Between 20 and 49 in number, they drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb.
Submental lymph nodes. Superficial lymph glands and lymphatic vessels of head and neck. (Buccinator glands labeled at center right.) The submental lymph nodes (or suprahyoid lymph nodes[citation needed]) are 2-3 lymph nodes [1] situated in the submental triangle, [1] between the anterior bellies of the digastric muscle and the hyoid bone.
