- The thymus is a lymphoid gland comprised of two identically sized lobes, located behind the sternum (breastbone) but in front of the heart. It derives its name from a resemblance it bears to the bud of the thyme plant (thymus in Latin).fter this age, the size of the thymus declines as the lymphoid tissue disappears and fat and fibrous tissue appears. T-cells have derived their name from the thymus, because this is where they are produced in the human body. Lymphoid stem cells are delivered to the outer cortex, or layer, of the thymus in blood.

What Is Thymus Cancer? The thymus is divided into 2 halves, called lobes. It has an irregular shape. There are a lot of small bumps called lobules on its surface. The thymus has 3 main layers: The medulla is the inside part of the thymus. The cortex is the layer that surrounds the medulla. The capsule is the thin covering over the outside of the thymus. The thymus reaches its maximum weight of about 1 ounce during puberty. Then it decreases in size during adulthood as it's replaced by fat tissue.

Tonsil and Adenoid Anatomy Overview. The palatine tonsils are dense compact bodies of lymphoid tissue that are located in the lateral wall of the oropharynx, bounded by the palatoglossus muscle anteriorly and the palatopharyngeus and superior constrictor muscles posteriorly and laterally. The adenoid is a median mass of mucosa-associated lymphoid tissue.

Thymoma & Other Thymic Tumors The thymus is a small organ located beneath the breastbone in the chest that functions as part of the lymphatic system, the body’s network for transporting infection-fighting white blood cells (lymphocytes) throughout the body. It produces T-lymphocytes and prompts B-lymphocytes to make antibodies that fight bacteria.

Thymus For other uses, see Thymus (disambiguation). The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells or T lymphocytes mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders. The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum.

Normal Structure, Function and Histology of the Thymus The thymus is the first of the lymphoid organs to be formed and grows considerably immediately after birth in response to postnatal antigen stimulation and the demand for large numbers of mature T cells. Genetic factors also influence the age of onset, rate and magnitude of thymus dependant immunological function.

Thymus Gland Function, Location, Anatomy and Parts The thymus gland is a flask-shaped organ lying in the lower neck and upper part of the mediastinum (superior mediastinum) in the chest cavity. It is an important part of the immune system in that it plays a major role in cell-mediated immunity.he thymus gland is most active in early life and this is reflected in its weight – 20 to 30 grams at birth, 30 to 50 grams up until puberty and 5 to 15 grams in old age. Its size at birth is approximately 50 millimeters in length and 40 millimeters in width with a variable thickness of about 6 millimeters.

Learn About the Thymus Gland Thymus The thymus gland is the main organ of the lymphatic system. Its primary function is to promote the development of specific cells of the immune system called T-lymphocytes. Once mature, these cells leave the thymus and are transported via blood vessels to the lymph nodes and spleen. T-lymphocytes are responsible for cell-mediated immunity, which is an immune response that involves the activation of certain immune cells to fight infection.

The thymus is located just below the throat, behind the sternum.wo irregularly shaped parts make up the thymus, which is located directly just below the throat, behind the sternum. The gland releases a hormone that stimulates the production of a certain type of white blood cell in the bone marrow; these cells, called thymocytes are transported by the bloodstream to the thymus.

The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum. Histologically, each lobe of the thymus can be divided into a central medulla and a peripheral cortex which is surrounded by an outer capsule. The cortex and medulla play different roles in the development of T-cells.
