Question

Which of the following is NOT a change typically produced by a hormone stimulus? A) Activates or deactivates B) Stimulates production of an action potential C) Alters plasma membrane permeability D) Induces secretory activity The ability of a specific tissue or organ to respond to the presence of a hormone is dependent on __. A) The location of the tissue or organ with respect to the circulatory path B) The membrane potential of the cell of the target organ C) The presence of the appropriate receptors of the cells of the target tissue or organ D) Nothing-all hormones of the human body are able to stimulate any and all cell types because hormones are powerful and nonspecific Several hormones are synthesized in the hypothalamus and transported to the anterior pituitary gland. The mechanism of transportation from hypothalamus to anterior pituitary gland is through the _ A) Hepatic portal system B) General circulatory system C) Hypophyseal portal system D) Feedback loop The neurohypophysis or posterior lobe of the pituitary gland is not a true endocrine gland because __. A) It is strictly a part of the neural system and has little or nothing to do with hormonal release B) Embryonically it was an endocrine tissue, but in the adult human it is no longer functional C) It is unable to function as an endocrine tissue because it is actually part of the neural system due to its location D) It is only a hormone storage area that receives hormones from the hypothalamus lot release When it becomes necessary to enlist the fight-or-flight response, a hormone that is released during the alarm phase of the general adaptation syndrome is __. A) Estrogen B) Epinephrine C) Angiotensinogen D) Renin The major targets of growth hormone are __. A) The blood vessels B) The adrenal glands C) The liver D) Bones and skeletal muscles

Explanation / Answer

42) The stimulus production of an action potential is a change that is not produced by the harmonal stimulus because it has several changes like activation and deactivation of enzymes,inducing secretory activity,alteration of plasma membrane etc...So i think option B is correct.

43) The ability of specific tissue or organ to respond to the presence of harmone is dependent on the presence of appropriate receptors on the cells of target tissue or organ.So i think option C is correct.

44) The mechanism of transportation from hypothalmus to anterior pitutary gland through the hypophyseal portal system.So the correct answer is option C.

45) A flight-flight response, a harmone released during the alarm phase of general adaption syndrome is epinephrine.So i think option B is correct.

46) As we all well known that the major target of growth harmones are bones and skeletal muscles because they play major role in the growth of harmones in both humans and also in animals.
