endocrine glands dump hormones and proteins directly into the bloodstream.  They have a large bloodflow to them, so they can release their products into that blood stream.  Endocrine glands are responsible for a majority of the homeostasis of the body.  look on wikipedia.org for more info.

hi, Dr Diana Schwarzbein has a wonderful book called The Schwarzbein Principle - you can probably get it at your library.  In back of the book it says she founded The Endocrinology Institute of Santa Barbara in 1993.  She sub-specializes in metabolism, diabetes, osteoporosis, menopause and thyroid conditions, subjects she lecture on frequently.  She lives.. in Santa Barbara..  very good info!

Diabetes is itself a derangement of the endocrine system. In type 1, a major endocrine system has completely failed. There is no insulin as a result of damage to the beta cells in charge of producing it. \n\nType 2 is more complicated. It is characteristically an inability of many body cells (about 2/3) to use insulin even if it's present. Some type 2s go on to have more insulin than normal in an attempt to get blood glucose levels down, or to beta cell death / exhaustion and reduced or no insulin. In any case, this is also a derangement of the endocrine system, also involving insulin.\n\nInsulin is tremendously important and is so important that it has been conserved across large evolutionary distance and time. The nematode worm, c elegans, uses insulin in much the same way and for the same purposes, that we do. So do fish. Beef insulin is exactly the same hormone as human insulin, except that it differs in two amino acids, and pork insulin is even closer, only one different amino acid. \n\nAs such, it's a great signal to rely on for controlling many things. If there's biochemical energy available, then protein synthesis will be possible, energetically. So cells use insulin levels to control amino acid uptake from blood stores. And similarly for electrolyte balances across cell membranes. And similarly for mobilization (or storage) of excess calories in the form of fats; if there's glucose in the blood, insulin levels will be high and so fats in the diet should be stored against future need. If there's little glucose in the blood, insulin will be low, and so energy in stores (ie, fat cells) should be used -- fats get dumped in the blood (as blood lipids), taken to the liver and turned into fuel for the rest of the body. (This is called ketosis, and it's the basis of the Atkins diet, though such diets are not 'normal' and, especially for diabetics, should be used with great caution. Diabetic ketoacidosis is a serious medical emergency and can be triggered by dietary derangements.) And so on and so on. \n\nInsulin is the direct cause of, or the indirect cause of, a great many things throughout the body. Consequences of its presence or absence are many, important, serious and cannot be too far wrong lest the damage be severe enough to cause damage or death.

Pituitary gland\n\nThe most important of the endocrine glands (glands that release hormones directly into the bloodstream), the pituitary is located at the base of the brain. Sometimes referred to as the "master gland," it regulates and controls the activities of other endocrine glands and many body processes including growth and reproductive function. Also called the hypophysis.

With hormone replacement you should still be able to get pregnant.\n\nYour thyroid gland plays a part along with many of your other endocrine system glands to regulate certain body functions.  Without it you may have to take a replacement hormone to helpregulate the other parts of your endocrine system but the loss of your thyroid should not make you totally incapable of becoming pregnant.  It may affect other organs which could affect your ability to become pregnant -due to the lack of the hormones that the thyroid produces- but you should still be able to concieve.  You should be asking your doctor this question and not Yahoo!

I am no doctor, but I believe that endocrine system diseases are caused by internal factors. However, there are diseases that could have a negative effect on the endocrine system. \n\nCheck this site for more info: http://www.answers.com/endocrine+system&r=67

I think it's D. Whatever it is please educate me on it. I happen to have issues with my thyroid, steming from being insulin resistent. Seems that the thyroid controls many hormones and once they are out of whack there is no telling what can happen. It's been fun to say the least.

I would check out http://www.answers.com/endocrine%20system. This site will give you answers from very reputable sources like Columbia University Press, Houghton Mifflin Company, and others.  It's a good place to start.  You should also check out www.jstor.org.  They have a bunch of full-text articles that have been written.\n\nGood luck!

They both maintain homestasis, but the big difference is time. Endocrine - slow, long term effects. Nervous system - fast, short lived effects.

Well the endocrine system is a network,and they all affect eachother,however Pineal gland has an entirely different function from the Adrenals,the Adrenals primarily excrete cortisol and Adrenaline.Serotonin is a chemical in the brain that makes that happy feeling.In depressed people there is a deficiency of seretonin.

STH\nsomatotropic hormone\n\nGrowth hormone\nGrowth hormone is a polypeptide hormone synthesised and secreted by the anterior pituitary gland which stimulates growth and cell reproduction in humans and other vertebrate animals.\nThis article describes human growth hormone physiology, with brief mentions of the diseases of GH deficiency, GH excess (acromegaly and pituitary gigantism), as well as GH treatment, and HGH quackery. Each of these topics is treated more fully in separate articles.\n\n----------------------------------------------------------\n\nSth\n■  abbreviation south. \n\n----------------------------------------------------------

Too many hormones.Until now, there are about 50 plus hormones discovered in human body(that is what my lecture told me-she's a Dr. actually).\nHormones can be divided into 2 broad classes: lipid-soluble hormones and water-soluble hormones.\n\n1.Lipid-soluble hormones\nLipid-soluble hormones include steroid hormones,thyroid hormones and nitric hormones.\nSteroid hormones are derieved from cholesterol.\nThyroid hormones (triiodothyronine or T3 and thyroxine or T4) are synthezed by the thyroid hormones\nNitric Oxide(NO) is both a hormone and a neurotransmitter.\n\n2.Water-soluble hormones\nThis include the amine hormones,peptide and protein hormones and eicosanoid hormones.\n\nA)Amine hormones retained an amino group on them.Examples are the epinephrine and norepinephrine.\nB)Peptide and protein hormones are amino acid polymers.Examples are the antidiuretic hormone and oxytocin.\nC)Eicosanoid hormones are derived from arachidonic acid.Examples are the prostaglandins and leukotrienes.\n\nThat's the most simple answer that i can gave to you.Actually, it 's much more complicated than this.Hope this helps ya!

The endocrine system is a control system of ductless glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distant organs. Hormones act as "messengers", and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them. The endocrine system does not include exocrine glands such as salivary glands, sweat glands and glands within the gastrointestinal tract.\n\nThe field of medicine that deals with disorders of endocrine glands is endocrinology, a branch of the wider field of internal medicine.\n\nHypothalamus \nThyrotropin-releasing hormone (TRH) \nGonadotropin-releasing hormone (GnRH) \nGrowth hormone-releasing hormone (GHRH) \nCorticotropin-releasing hormone (CRH) \nSomatostatin \nDopamine \nPituitary gland \nAnterior lobe (adenohypophysis) \nGH (human growth hormone) \nPRL (prolactin) \nACTH (adrenocorticotropic hormone) \nTSH (thyroid-stimulating hormone) \nFSH (follicle-stimulating hormone) \nLH (luteinizing hormone) \nPosterior lobe (neurohypophysis) \nOxytocin \nADH (antidiuretic hormone) \nPineal gland \nMelatonin \nThyroid gland \nThyroxine (T4), a form of thyroid hormone \nTriiodothyronine (T3), a form of thyroid hormone \nCalcitonin \nParathyroid gland \nParathyroid hormone (PTH) \nHeart \nAtrial-natriuretic peptide (ANP) \nStomach and intestines \nGastrin \nSecretin \nCholecystokinin (CCK) \nSomatostatin \nNeuropeptide Y \nLiver \nInsulin-like growth factor \nAngiotensinogen \nThrombopoietin \nIslets of Langerhans in the pancreas \nInsulin \nGlucagon \nSomatostatin \nAdrenal glands \nAdrenal cortex \nGlucocorticoids - cortisol \nMineralocorticoids - aldosterone \nAndrogens (including testosterone) \nAdrenal medulla \nAdrenaline (epinephrine) \nNoradrenaline (norepinephrine) \nKidney \nRenin \nErythropoietin (EPO) \nCalcitriol \nSkin \nCalciferol (vitamin D3) \nAdipose tissue \nLeptin \n\nIn males only\nTestes \nAndrogens (testosterone) \n\nIn females only\nOvarian follicle \nOestrogens \nTestosterone \nCorpus luteum \nProgesterone \nPlacenta (when pregnant) \nProgesterone \nHuman chorionic gonadotrophin (HCG) \nHuman placental lactogen (HPL) \n\nRole in disease\nDiseases of the endocrine system are common, such as diabetes mellitus and thyroid disease.\n\nEndocrineopathies can occur with any of these. Hypofunction can occur as result of loss of reserve, hyposecretion, agenesis, atrophy, destruction, etc. Hyperfunction can occur as result of hypersecretion, loss of suppression, tumor, hyperplasia, etc.\n\nEndocrineopathies are classified as primary, secondary, or tertiary.\n\nPrimary is target organ dysfunction and is normally associated with increased or decreased secretory hormones. Secondary is a dysfunction that originates elsewhere like the pituitary gland and is normally associated with increased or decreased production of trophic factors. Tertiary is associated with dysfunction of the hypothalamus and its releasing hormones.\n\nDiffuse Endocrine System\nOrgans aren't the sole way for hormones to be sent into the body; there are a host of specific cells which secrete hormones independently. These are called the "diffuse" endocrine system, and include myocytes in the heart (atria) and epithelial cells in the stomach and small intestines. In fact, if one were to classify any chemical excretions in the term "hormone," every cell in the human body could be considered a part of the endocrine system.

Endocrine refers to all hormones, not just those of the pancreas.  They are made in one cell and released into the blood stream where they work on distant cells.\n\nNeurological transmissions are predominately electrical.  The neuron gets depolarized and sends an electric signal down its axon (long process of the cell) to where it will be going to  (a muscle for example).  When the electric signal reaches its destination (the end of the axon) it causes a release of a neurotransmitter from the axon (each axon only releases one type of neurotransmitter).  These transmitters diffuse to where they are going (a muscle for example) and cause a change in that cell.\n\nSome similarities are that both hormones and neurotransmitters have specific receptors for them and they both cause changes in the cells that they interact with.  Also, there are some neurotransmitters that are hormones, they are released from the end of the axon into the bloodstream and then go to distant cells to do their work.

Insulin is a hormone that regulates the glucose level in blood. It is a hormone secreted by the islets of Langerhans in the pancreas that regulates the level of glucose in the blood. Deficiency in production results in diabetes mellitus.
