The thymus (pl.: thymuses or thymi) is a specialized primary lymphoid organ of the immune system. Within the thymus, thymus cell lymphocytes or T cells mature. T cells are critical to the adaptive immune system, where the body adapts to specific foreign invaders. The thymus is located in the upper front part of the chest, in the anterior ...
The thymus is located between the inferior neck and the superior thorax. At puberty, by the early teens, the thymus begins to atrophy and regress, with adipose tissue mostly replacing the thymic stroma.
Sweetbread is a culinary name for the thymus (also called throat, gullet, or neck sweetbread) or pancreas (also called stomach, belly or heart sweetbread), typically from calf (French: ris de veau) or lamb (ris d'agneau). [1][2] Sweetbreads have a rich, slightly gamey flavor and a tender, succulent texture. They are often served as an appetizer ...
The hypothalamus, pancreas, and thymus also function as endocrine glands, among other functions. (The hypothalamus and pituitary glands are organs of the neuroendocrine system . One of the most important functions of the hypothalamus—it is located in the brain adjacent to the pituitary gland—is to link the endocrine system to the nervous ...
Thymocyte. A thymocyte is an immune cell present in the thymus, before it undergoes transformation into a T cell. [1] Thymocytes are produced as stem cells in the bone marrow and reach the thymus via the blood. Thymopoiesis describes the process which turns thymocytes into mature T cells according to either negative or positive selection.
H&E stain. Hassall's corpuscles (also known as thymic bodies) are structures found in the medulla of the human thymus, formed from eosinophilic type VI thymic epithelial cells arranged concentrically. These concentric corpuscles are composed of a central mass, consisting of one or more granular cells, and of a capsule formed of epithelioid cells.
The thymus is a primary lymphoid organ of the immune system. It is a butterfly-shaped organ consisting of two lobes, located in the top part of the chest, that supports T cell development via specialized microenvironments that ensure a diverse, functional, and self-tolerant T cell population.
Thymic epithelial cells (TECs) are specialized cells with high degree of anatomic, phenotypic and functional heterogeneity that are located in the outer layer (epithelium) of the thymic stroma. The thymus, as a primary lymphoid organ, mediates T cell development and maturation. The thymic microenvironment is established by TEC network filled ...
