BIOD 151 MODULE 6 EXAM TESTED
QUESTIONS AND COMPLETE SOLUTIONS
◉ 12. List the hormone(s) that best describes the statement
below: I am secreted by the beta cells of the pancreas.
Answer: Insulin
◉ 12. List the hormone(s) that best describes the statement
below: I am secreted by the pituitary to stimulate the adrenal
cortex.
Answer: ACTH
◉ 13. List the hormone(s) that best describes the statement
below: I cause blood glucose to rise and breakdown stored
nutrients.
Answer: Glucagon
◉ 13. List the hormone(s) that best describes the statement
below: I am secreted by the alpha cells of the pancreas.
Answer: Glucagon
◉ 14. Answer the following question. Explain in detail how PTH
and calcitonin work to maintain calcium balance.
Answer: Calcitonin: produced by the thyroid glands, deposits
calcium into bone. Calcitonin opposes the ac!on of PTH. When the
, blood calcium level reaches the appropriate level through all these
means, the parathyroid glands stop producing PTH through
nega!ve feedback. PTH: produced by the parathyroid glands
increase the amount of calcium in the blood. (Any one of the
following explana!ons of PTH is acceptable) PTH s!mulates the
increased absorp!on of calcium from the intes!nes. PTH retains
calcium through excre!ng phosphate at the kidneys. In the bones,
PTH promotes the ac!vity of osteoclasts to demineralize of the
bone, increasing the amount of calcium in the blood.
◉ 14. Explain why it would be harmful to have an increased
secretion of ACTH in someone who is diabetic.
Answer: ACTH controls the secretion of cortisol from the adrenal
cortex. Increased levels of ACTH would cause increased levels of
cortisol within the blood. Cortisol increases blood glucose levels
which will decrease the effectiveness of insulin treatments.
◉ 15. Which hormone/s are involved in milk production? A.
Thyroxin B. Oxytocin C. Prolactin D. B &C E. A&B
Answer: C
◉ 15. Where is thyroid stimulating hormone produced? A. Pineal
B. Thyroid C. Thymus D. Anterior Pituitary E. Posterior Pituitary
Answer: D
◉ 16. Which gland decreases in size with age?
Thyroid
