What is the medullary cord?
Medular cord is a dense structure in the lymph node and is composed of lymphatic tissue. Medular cords are located in the medulle lymph nodes, located in the center of the node. They work by creating antibodies that flow out of the lymph nodes through a lymphatic fluid. These cords also contain numerous macrophages that clean the lymphatic fluid before leaving the knot.
Medular tissue cords make up most of the medully lymph nodes. The cords are separated by medular cavities, which are the spaces through which the lymphatic fluid flows. However, the barrier between the medular cords and the cavities is not solid, so the cords project into the cavities to interact with the lymphatic fluid that flows through them. While the lymphatic fluid is in contact with the medular cord, the cells in the cord store antibodies and remove harmful materials. The fluid then flows from the lymph node to fight the antigens found in the rest of the body.
Most found cells found Medular cord are bPlasma cells, B cells or macrophages. Plasma cells are white blood cells that produce a large number of generalized antibodies, and B cells are a type of lymphocyte that produces antibodies against specific antigen. The macrophages act as a filter for lymphatic fluid by identifying and removing the material material contained in the liquid.
Medular cords are part of a lymphoid system that captures foreign particles and fights infection throughout the body. When the body encounters infection, the immune reaction occurs primarily in the lymph node. Structures inside the lymph nodes accumulate excess lymphatic fluid and swollen, causing the entire gland to appear enlarged.
infections that usually cause enlarged lymph nodes include abscesses, ear infections, tonsillitis, skin infections and colds. Tuberculosis, mononucleosis, gingivitis, ulcers and sexually portableDiseases can also cause enlarged lymph nodes. Lymph nodes can also swell when an individual has autoimmune disease, leukemia, Hodgkin's disease or lymphoma.
Medular cord is an essential part of the human immune system. In individuals who have a chronic immune deficiency, such as a lack of human immunodeficiency virus, Medular cords or other structures in the lymph node may not work properly. Medular cord does not have to produce enough antibodies to combat infection, or B cells in the medular cord may not work as they should. In such cases, otherwise mild infection may lead to serious illness or even death.
