Nursing: Endocrine System

DISCUSSION:- The endocrine system includes all of produced by those glande. The glands nervous system as well as are the glands of the body and the hormone controlled directly by stimulation from the by cherical receptors in the blood and hormones produced by other glande. By regulating the functions of orgone in the body, these glande help to maintain the body's homeostasis. Cellular metabolism, reproduction, sugar in are among the and mineral homeostalie, sexual developrrent, heart rate and digestion are among the many processes regulated by the actions of hormones. Hypothalamus The hypothalamus is a part of the brain located superior and anterior to the brain stem and inferior to the thalarrus. It serves many different functione in the nervous system, and is also responsible for the direct control of the endocrine system thorough the pituitary gland. The hypothalarus contains special cells called neuralerator cells-neurons that serete hormones: Shyrotropin-releasing hormare (TRH) frowth hormone releasing hormone (GHRH) Growth hormone inhibiting hormone (GHIH) Gonadstropin-releasing hortone (GnRH) Corticotropin-releasing hormone (CRH) Oxytosin Antidiuretic hormone (ADH). Pituitary gland The pituitary gland, also known as hypophysis, is a small pea-rized lump of tissue connected to the inferior portion of the hypothalarus of the brain. Oxytorin triggers uterine contractions during childbirth and the release of milk during Breastfeeding. Antidiuretic hercione (ADI) prevents water loss in the body by increling, the re-uptake of water in the kidneys and reducing blood flow to sweat glande. Prolactin (PRL) has many effects on the body chief of which is that it stirculates the Mammary glands of the breasts to produce Milk. Pineal gland The pined gland is a small pinecone - shaped mess of glandular tissue found jus posterior to the thalarus of the brain. The pined gland produces the horrore relatonin that helps to regulate the hurren sleep awake cycle known as the circardion rythem. Thyroid gland the thyroid gland is a butterfly shaped gland located at the base of the neck and wrapped around the lateral sides of the trachen. The thyroid gland produce 3 Mojar harmones! Calcitonin Sriiodothyronine (13) Thyroxine Pancreas The pondress is a large gland located in the abdorrinal cavity just inferior and posterior to the stomach she pancreas is considered to be a heterocrine gland as it contains both endocrine and coxocrine tissue. The endocrine cells of the pancreas Make up just about 1% of the total mass of the pancreas and are found and are found in small groups throughout the pancreas colls islets of Longerhans. Within these islets are & types of cells -alpha and beta cells. Parathyroid gland The parathyroid glands are 4 small masses of glandular tissue found on the posterior side of the thyroid gland. The parathyroid glands produce the harmone parathyroid hormone (PTH), which is involved in calcium ion horeostalis. Adrenal glands The adrenal glands are a pair of roughly trianguler glands found immediately superior to the kidneys. The adrenal glands are each made of 2 distinct layere each with their own wrique functione: the outer cortex and inner adrenal medulla Gonads She gonads - ovaries in perrales and tester in males are responsible for producing the sex hotmones of the body. Shave for hormones deterreine the secondary sex characteristics of adult permales and adult males. Thyrus The thyrul is soft, triangular shaped digen found the chest posterior to the sins that help to train sternum. The thyrus produced hormones called thyresins and develop T-lymphocytes during fetal development and childhood. HormAnal Regulation The levels of hormones in the body con be regulated by several factore. The nervous systere con control hormone levels through the action of the hypothalarius and its releasing and inhibiting hormones.
