BIO 2301 LECTURE EXAM 2 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
what is the basic function of the endocrine system? - CORRECT ANSWER -
communication
what other system which we have studied shares endocrine function? - CORRECT
ANSWER - circulatory system
excrete and excretion - CORRECT ANSWER - to release a substance to the outside of the
body; the thing that is being released outside of the body
secrete and secretion - CORRECT ANSWER - to release a substance within the body; the
thing that is being released inside the body
hormones - CORRECT ANSWER - secretion that acts on a distant target
paracrine secretions - CORRECT ANSWER - secretion that affects near-by target
autocrine secretions - CORRECT ANSWER - secretion that affects the cell that secreted it
what is the purpose of the hypophyseal portal vein? - CORRECT ANSWER - carries
hormone from hypothalamus to anterior pituitary vein; allows brain to manage pituitary
where does the hypophyseal portal vein start? - CORRECT ANSWER - hypothalamus
where does the hypophyseal portal vein go? - CORRECT ANSWER - anterior pituitary
, what mineral is required for thyroid hormone production? - CORRECT ANSWER - iodine
how do the thyroid hormones affect cells? - CORRECT ANSWER - increase metabolic
rate; inhibit secretion of TSH and TRH
under what conditions is thyroid hormone secreted? - CORRECT ANSWER - increased
releasing of thyrotropin releasing hormone (TRH) from the anterior pituitary
name the hypothalamic and pituitary hormones which regulate thyroid hormone secretion -
CORRECT ANSWER - TSH (thyroid stimulating hormone) and TRH (thyrotropin
releasing hormone)
describe the feedback mechanism which prevents excessive thyroid hormone secretion -
CORRECT ANSWER - negative feedback from increased secretion of thyroid hormone
prevents excessive thyroid hormone secretion. more thyroid hormone inhibits the secretion of
TSH and TRH.
what would happen to thyroid hormone and TRH secretion if an individual was injected with a
large dose of TSH? - CORRECT ANSWER - increased TRH secretion and increased
thyroid hormone secretion, increasing metabolic rate
from what gland is GH secreted? - CORRECT ANSWER - anterior pituitary
name the two major functions of GH - CORRECT ANSWER - increases blood glucose,
regulates growth
how does growth hormone affect protein synthesis? - CORRECT ANSWER - increases
protein synthesis because of the growth spurt: more fuel out in the blood to build stuff
how does growth hormone affect blood glucose? - CORRECT ANSWER - growth
hormone increases blood glucose levels
