The Endocrine System and Discrete Endocrine Organs

trenchant variety meat, such as the pituitary and the thyroid, atomic number 18 constituents of a walloping and intrinsic system of ductless glands, commonly referred to as hormone glands. However, several non- separate organs alike let endocrinal gland wanders and sour like endocrinal glands, and so-and-so therefore be referred to as endocrine 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 generate their hormones directly into the blood stream, bypassing whatsoever sort of exocrine characterized, waxy framework. The true, discrete organs of the endocrine system include the undermentioned glands: The hypothalamus, pituitaries, pineal, thyroid and para-thyroid and the adrenals. The non-discrete endocrine organs, those which possess endocrine tissues, include the future(a): The gastrointestinal and respiratory tracts, pan creas, heart, kidneys, testes, ovaries, placenta, and the thymus. The pineal gland is located darksome within the brain, thus feces be considered discrete or non-discrete. Additionally, and for practical reasons, several of the non-discrete organs with endocrine tissues are simply 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 passim the body. This stabilization, in turn, ultimately enhances the legion(predicate) mammalian functions that must travel by every day of our lives. The epithelial cells of endocrine tissues are extremely active; generally, these cells present conspicuously stained nuclei and cytoplasmic organelles. The mitochondria, Golgi bodies, secretory granules and endoplasmic reticulum are the principal(prenominal) contributors to the cells prominent cytoplasmic detection character. Two general types of ho rmones are produced and secreted from endocrine g...
