endocrine system
organs or groups of cells that secrete regulatory substances that are released directly into the circulation (hormone). The endocrine or hormonal system and the nervous system are the two major control systems of the body, and their functions are interrelated. Hormonal activity is mostly concerned with regulating metabolic activities by controlling the rates at which chemical reactions take place within cells, the transport of substances across the cell membrane, and activities related to growth and reproduction. The word hormone is applied to substances released by the endocrine glands that have physiological effects on target organs (which can be other endocrine glands) and tissues distant from the gland. There are, however, local hormones (autacoids) secreted at the site of the tissue being affected, for example, acetylcholine and serotonin.
endocrine tumor
adenoma or carcinoma; usually only one cell type, that of the normal tissue, but may be more than one type of cell capable of secreting more than one hormone.
