Lecture 45 study guide notes typed 1) Make a chart of all hormones once class is over on chapter 47 1) Hormones work as a team together because to obtain the same goal or to maintain homeostasis. 1) endocrine glands- produces and releases hormones throughout the body 2) exocrine gland- secretes hormones to the outside of the body ducts. 3) Paracine signaling is a form of cell-cell communication in which a cell produces a signal to induce changes in nearby cells. 4) Hormones- chemical messengers secreted directly into the blood where tissues and organs exert there functions. 5) These two are similar in that they both tell cells what to do for the body but hormones are told to be used by the body the cells will tell other cells to change just because of the situation. 6) The three main types are the Adrenaline, Cortisol, Norepinephrine. 7) Water soluble hormone can diffuse faster and work quicker because it gets broken down by fluid. 8) Lipid soluble takes longer to work because it gets used and broken down by fat in your body. 9) Target cells are effected in different ways because it ends up telling the hypothalamus to act different like in female reproductive system when the hypothalamus gets high levels of E hormone. 10) And 9) 11) Alla bout your diabeties and how to regulate it. Alpha cells-secrete glycogen 12) Beta cells- produce insulin. 13) 10) Thyroid gland- controls your growth and the rate of your metabolism. 14) To prevent hypothyroidism and hyperthyroidism are to use steroids in pill form or shots of growth hormone. 1) The mineral is Iodine where most people get in there salts because it is put into them. If you don’t get enough your thyroid will keep growing and growing 2) Hypothalamus controls both the anterior and posterior pituitary glands from secreting a hormone telling them to activate. 3) & 14) Anterior- ACTH, TSH, LH, FSH, PRL, GH, MSH 4) Postierior- secretes an anti direct to regulate water and blood pressure. 1) Negative feeback from the thyroid hormone from the hypothalmus telling the putitary glands to stop the thyroid gland from working so hard. 2) Goiters happen when the thyroid gland keeps working and working realsing hormones and never being told to stop causing a huge swelling bulb across the neck from growht. 3) Calcium is needed very much so for these glands to work they will take calcium from the body but if you dont make enough you have to get it from the bones. 4) The adrenal medulla-help the body control blood sugar, burn protein and fat and react to stressors and regulate blood pressure. 5) Adernal hormones go straight to the thyroid gland and hypothalmus. 6) Gondal steroids, estrogen, testostrone, 7) endocrine disrupter-chemicals at certain doses can interfere with the endocrine system in mammals.
