The Endocrine System and Discrete Endocrine Organs

Discrete organs, such(prenominal) as the pituitary and the thyroid, be constituents of a large and inbuilt organisation of ductless secretory organs, usually referred to as internal secretion glands. However, some(prenominal) non- clear-cut organs also hold endocrinal tissues and function give care hormone glands, and can hence be referred to as internal secretion glands. Collectively, these two groups of discrete and non-discrete organs make up the ductless gland system. Endocrine tissue is for the most part represented by aggregates of secretory epithelial cells that deliver their hormones like a shot into the blood stream, bypassing any bod of exocrine characterized, ductile framework. The true, discrete organs of the endocrine gland 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 respi ratory tracts, pancreas, heart, kidneys, testes, ovaries, placenta, and the thymus. The pineal gland is located deep inside the brain, thus can be considered discrete or non-discrete. Additionally, and for applicatory 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 discover of hormones, which is finely regulated and coordinated, provides homeostatic stability throughout the body. This stabilization, in turn, ultimately enhances the numerous mammalian functions that must occur each day of our lives. The epithelial cells of endocrine tissues are highly active voice; generally, these cells present with child(p)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. ii general types of hormones are produced and secreted from endocrine g...
