The Endocrine System and Discrete Endocrine Organs

trenchant variety meat, such as the pituitary body and the thyroid, atomic number 18 constituents of a humongous and intrinsic system of ductless glands, commonly referred to as endocrinal glands. However, several non- discrete organs besides take ductless gland tissues and operation like internal secretion glands, and stern therefore be referred to as hormone glands. Collectively, these two groups of discrete and non-discrete organs make up the endocrine system. Endocrine tissue is generally represented by aggregates of secretory epithelial cells that own their hormones directly into the blood stream, bypassing either sort of exocrine characterized, bendable framework. The true, discrete organs of the endocrine system include the by-line glands: The hypothalamus, pituitaries, pineal, thyroid and para-thyroid and the adrenals. The non-discrete endocrine organs, those which possess endocrine tissues, include the pursuance: The gastrointestinal and respiratory tracts, pancreas, heart, kidneys, testes, ovaries, placenta, and the thymus. The pineal gland is located mysterious within the brain, thus atomic number 50 be considered discrete or non-discrete. Additionally, and for practical reasons, several of the non-discrete organs with endocrine tissues are entirely referred to as endocrine organs, e.g. the endocrine pancreas, or the endocrine heart. \nThe endocrine glands release of hormones, which is finely regulate and coordinated, provides homeostatic stability end-to-end the body. This stabilization, in turn, ultimately enhances the many mammalian functions that must encounter every day of our lives. The epithelial cells of endocrine tissues are highly active; generally, these cells present prominently stained nuclei and cytoplasmic organelles. The mitochondria, Golgi bodies, secretory granules and endoplasmic reticulum are the chief(prenominal) contributors to the cells prominent cytoplasmic dapple character. Two general types of horm ones are produced and secreted from endocrine g...
