Definition

• Appendix: a tube 2cm-7cm long at base of ileocecal juncture dense with lymphocytes
• Cortex: the outer, C shaped, noduled covering of lymph node
• Hilum: medulla of thymus extending to the surface
• Hodgkin's lymphoma: one of two types of cancers of the lymphatic system caused by rapid replication of B cells
• Lymph sac: the embryonic growths along major veins that develop into lymphatic vessels
• Lymph sinuses: the channels of clear space between the capsule/trabeculae and the parenchyma and stroma
• Peyer's patches: the clusters of lymphatic nodules found in the small intestine (ileum)
• Plasms cell: a cell that differentiates from B cells and secretes antibodies in immune response
• Sentinel node: the first lymph node(s) cancer cells are likely to have spread from after the primary site infection, a biopsy of the node identifies metastasis
• Stroma: compact reticular connective tissue found inside thymus
• T cell: the prominent cell in immune response; thymus dependent lymphocyte
• Tonsils: the multiple lymphatic tissues (organ) located at the pharynx that shield the body from inspired or ingested pathogens, three total
• White and red pulp: named corresponding to (fresh) sections of the spleen, white connotes lymphocytes and macrophages near the splenic artery, red corresponds to erythrocytes in the sinuses
• Anabolism: a building process where simple substances are converted to more complex compounds

• Hypoglycemia: an abnormally low blood glucose level
• Hyperemesis: excessive vomiting
• Hyperglycemia: elevated blood sugar level
• Adenocarcinoma: carcinoma that originated from cells of glands
• Adenopathy: an increase in the size of glands often referring to lymph nodes
• Adipocyte: a fat cell
• Adipsuria: fat in the urine
• Biopsy: to examine a piece of tissue from the body for diagnosis
• Biogenesis: the origin of life
• Calcaneus: the heel bone
• Calcification: hardening of tissue due to calcium deposition
• Cellular: pertaining to or made of cells; consisting of small compartments
• Cellulose: organic polymer of thousands of glucose molecules found in plant walls and food
• Achromasia: hypopigmentation; lack of staining power in a cell or tissue
• Chromoblast: embryonic cell that develops into a pigment cell]
• Cytokinesis: final stage of cell division when the cytoplasm splits
• Cytology: the study of cells
• Dermatology: a branch of medicine that deals with the skin
• Erythroderma: an abnormal redness of the skin
• Fibroma: a tumor composed of mainly fibrous tissue
• Fibrochondritis: inflammation of fibrocartilage
• Carcinogenic: a cancer producing agent
