If every cell and tissue in the body can potentially \"see\" or be exposed to a hormone, why do only certain ones respond? a All tissues DO respond to all hormones, some just to a greater extent. b. All tissues don\'t necessarily get exposed to all hormones. c The tissues that respond are the ones who express the appropriate receptors. Only certain ones respond because the brain tells them to. e. Both a & d Hormones binding their receptors may result in ___. a alteration of membrane permeability and or membrane potential b activation of intracellular enzymes c inactivation of enzymes d. all of the above e. only a & c Which of the following will result from prolonged \"stress\" on one\'s system? 1. Retention of Na^+ (and therefore water) by the kidneys 2. Elevated glucocorticoid levels 3. Elevated blood glucose possibly progressing into Type II Diabetes Mellitus 4. suppression of the immune system 5. Elevated aldosterone levels in the blood 6. Increased blood pressure (hypertension) due to excessive or elevated blood volume a. 1, 3, 5, 6 b. 1, 2, 3, 5 c. 1, 2, 4, 5, 6 d. 2, 3, 4, 5, 6 e. All of the above The hypothalamus functions in the ___. 1. control of body temperature 2. production of neurohypopbseal hormones 3. Coordination of ANS 4. control of thirst & hunger 5. control of urine output 6. control of the adenohypophysis a. 1, 2, 3 b. 2, 4, 5, 6 c. 2, 3, 5 d. 1, 2, 4, 6 e. 1, 2, 4, 5, 6, Which of the following formed elements are NOT living cells? 1. Neutrophils 2. Erythrocytes 3. Basophils 4. Thrombocytes 5. Eosinophils 6. Lymphocytes a. 1, 3, 5 b. 2, 4, 6 c. 1, 2, 3, 5 d Only 2 & 4 e. All of the above Solution Answer 76 ] every cell & tissue in the body can potentialy see or be exposed to hormones why do certain cells respond C] The tissues that respond are the one who express the appropriate receptors Explaination= hormones are chemical messengers secreted into the blood or extracellular fluid by one cell that affects the functioning of other cells most hormones circulate in the blood coming in the contact with essentially all cells however a given hormone usually affects only a limited number of cells ,called as a target cells A target cell respond to a hormone because it contains receptors for the hormone & cells who do not have particular receptor for that hormone can not respond & not influenced.
