The Endocrine System and Discrete Endocrine Organs

Discrete organs, such as the pituitary and the thyroid, atomic number 18 constituents of a large and integral arrangement of ductless glands, unremarkably referred to as internal secretion glands. However, some(prenominal) non- trenchant organs also receive hormone tissues and function equal internal secretion glands, and can so be referred to as internal secretion glands. Collectively, these two groups of discrete and non-discrete organs make up the endocrine gland system. Endocrine tissue is loosely represented by aggregates of secretory epithelial cells that deliver their hormones at once into the blood stream, bypassing any expression of exocrine characterized, ductile framework. The true, discrete organs of the endocrine system include the following glands: The hypothalamus, pituitaries, pineal, thyroid and para-thyroid and the adrenals. The non-discrete endocrine organs, those which possess endocrine tissues, include the following: The GI and respiratory tract s, pancreas, heart, kidneys, testes, ovaries, placenta, and the thymus. The pineal gland is located deep inwardly the brain, thus can be considered discrete or non-discrete. Additionally, and for applicative 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 dislodge of hormones, which is finely regulated and coordinated, provides homeostatic stability throughout the body. This stabilization, in turn, ultimately enhances the numerous mammal functions that must occur all day of our lives. The epithelial cells of endocrine tissues are highly progressive; generally, these cells present big(a)ly stained nuclei and cytoplasmic organelles. The mitochondria, Golgi bodies, secretory granules and endoplasmic reticulum are the main contributors to the cells prominent cytoplasmic staining character. two general types of hormones are produced and secr eted from endocrine g...
