The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells mature. T cells are critical to the adaptive immune systemwhere the body adapts specifically to foreign invaders. The thymus is located in the upper front part of the chest, in the anterior superior mediastinumbehind the sternumand in front of the heart.
Sex and the city serie streaming is made up of two lobes, each consisting of a central medulla and an outer cortex, surrounded by a capsule. The thymus is made up of immature T cells called thymocytesas well as lining cells called epithelial cells which help the thymocytes develop.
T cells that successfully develop must react appropriately with MHC immune receptors of the body, called positive selectionand not reacting against proteins of the body, called negative selection. By the early teens, the thymus begins to decrease in size and activity and the tissue of the thymus is gradually replaced by fatty tissue. Nevertheless, some T cell development continues throughout adult life. Abnormalities of the thymus can result in a decreased number of T cells and autoimmune diseases such as Autoimmune polyendocrine syndrome type 1 and Sex in konstanz gravis.
These are often associated with cancer of the tissue of the thymus, called thymomaor tissues arising from immature lymphocytes such as T cells, called lymphoma. Removal of the thymus is called thymectomy. The thymus is an organ that sits beneath the sternum in the upper front part of the chest, stretching upwards towards the neck. In children, the thymus is pinkish-gray, soft, and lobulated on its surfaces. The thymus is made up of two lobes that meet in the upper midline, and stretch from below the thyroid in the neck to as low as the cartilage of the fourth rib.
The left brachiocephalic vein may even be embedded within the thymus. The thymus consists of two lobes, merged in the middle, surrounded by a capsule that extends with blood vessels into the interior. The cortex is mainly made up of thymocytes and epithelial cells. This network forms an adventitia to the blood vessels, which enter the cortex via septa near the junction with the medulla. In the medulla, the network of epithelial cells is coarser than in the cortex, and the lymphoid cells are relatively fewer in number.
Micrograph showing a lobule of the thymus. The cortex deeper purple area surrounds a less dense and lighter medulla. The arteries supplying the thymus are branches of the internal thoracicand inferior thyroid arterieswith branches from the superior thyroid artery sometimes seen. The veins of the thymus end in the left brachiocephalic veininternal thoracic veinand in the inferior thyroid veins.
Lymphatic vessels travel only away from the thymus, accompanying the arteries and veins. These drain into the brachiocephalic, tracheobronchial and parasternal lymph nodes. The nerves supplying the thymus arise from the vagus nerve and the cervical sympathetic chain. The two lobes differ slightly in size, with the left lobe usually higher than the right. Thymic tissue may be found scattered on or around the gland, and occasionally within the thyroid.
The thymocytes and the epithelium of the thymus have different developmental origins. Here the thymocytes and epithelium meet and join with connective tissue. The pharyngeal opening of each diverticulum is soon obliterated, but the neck of the flask persists for some time as a cellular cord. By further proliferation of the cells lining the flask, buds of Filipina sex website are formed, which become surrounded and isolated by the invading mesoderm.
The epithelium forms fine lobules, and develops into a sponge-like structure. Iodine is also necessary for thymus development and activity. The thymus continues to grow after the birth reaching the relative maximum size by puberty. The thymus facilitates the maturation of T Midi musik kostenlosan important part of the immune system providing cell-mediated immunity.
In the thymus they undergo a process of maturation, which involves ensuring the cells react against antigens "positive selection"but that they do not react against antigens found on body tissue "negative selection". Each T cell has a distinct T cell receptorsuited to a specific substance, called an antigen. The MHC presents an antigen to the T cell receptor, which becomes active if this matches the specific T cell receptor.
T cells have distinct T cell receptors. The survival and nature of the T cell then depends on its interaction with surrounding thymic epithelial cells. Here, the T cell receptor interacts with the MHC molecules on the surface of epithelial cells. A T cell that does react will survive and proliferate. T cells that attack the body's own proteins are eliminated in the thymus, called "negative selection".
As the thymus is where T cells develop, congenital problems with Wann sex haben development of the thymus can lead to immunodeficiencywhether because of a problem with the development of the thymus gland, or a problem specific to thymocyte development.
Immunodeficiency Thymusextrakte be profound. Because of defects in this condition, self antigens are not expressed, resulting in T Lena odenthal nackt that are not conditioned to tolerate tissues of the body, and may treat them as foreign, stimulating an immune response and resulting in autoimmunity.
Many other autoimmune diseases may also occur. Thymoma-associated multiorgan autoimmunity can occur in people with thymoma. In this condition, the T cells developed in the thymus are directed against the tissues of the body. This is because the malignant thymus is incapable of appropriately educating developing thymocytes to eliminate self-reactive T cells.
The condition is virtually indistinguishable from graft versus host disease. This is done by acetylcholinesterase inhibitors such as pyridostigmine. Tumours originating from the thymic epithelial cells are called thymomas. Thymusextrakte can be benign; benign but by virtue of expansion, invading beyond the capsule of the thymus "invasive thyoma"or malignant a carcinoma.
Tumours originating from T cells of the thymus form a subset of acute lymphoblastic leukaemia ALL. Genetic analysis including karyotyping may reveal specific abnormalities that may Sexy mode prognosis or treatment, such as the Philadelphia translocation.
Very high white cell counts may also require cytoreduction with apheresis. Tumours originating from the small population Thymusextrakte B cells present in the thymus lead to primary mediastinal thymic large B cell lymphomas. Other markers may also be used to confirm the diagnosis. Thymic cysts are usually detected incidentally and do not generally cause symptoms.
Thymectomy is the surgical removal of the thymus. When used as food for humans, the thymus of animals Thymusextrakte known as one of the kinds Kartenlegen kostenlos ich und du sweetbread. Galen was the first to note that the size of the organ changed over the duration of a person's life.
In the nineteenth century, a condition was identified as status thymicolymphaticus defined by an increase in lymphoid tissue and an enlarged thymus. It was thought to be a cause of sudden infant death syndrome but is now an obsolete term. The importance of the thymus in the immune system was discovered in by Jacques Millerby surgically removing the thymus from one day old mice, and observing the subsequent deficiency in a lymphocyte population, subsequently named T cells after the organ of their origin.
The thymus is present in all jawed vertebrateswhere it undergoes the same shrinkage with age and plays the same immunological function as in other vertebrates. Recently, a discrete thymus-like lympho-epithelial structure, termed the thymoidwas discovered in the gills of larval lampreys. A second thymus in the neck has been reported sometimes to occur in the mouse  As in humans, the guinea pig 's thymus naturally atrophies as the animal reaches adulthood,  but the athymic hairless guinea pig which arose from a spontaneous laboratory mutation possesses no thymic tissue whatsoever, and the organ cavity is replaced with cystic spaces.
On chest X-raythe thymus appears as a radiodense brighter in this image mass by the upper lobe of the child's right left in image lung. From Wikipedia, the free encyclopedia.
