Question

question 13 (1 point)
insulin and glucagon are produced in:
a) the pancreas
b) the thyroid
c) the pituitary
d) the kidneys
question 14 (1 point)
which of the following is not true for cortisol?
a) cortisol is a glucocorticoid hormone
b) cortisol tends to elevate blood glucose levels
c) cortisol is made in the adrenal cortex
d) cortisol stimulates the fight - flight response.

Explanation:

• Question 13:
• The pancreas has islets of Langerhans. Beta cells in these islets produce insulin, and alpha cells produce glucagon.
• The thyroid produces thyroxine and triiodothyronine.
• The pituitary has multiple functions like producing growth hormone, luteinizing hormone etc., but not insulin or glucagon.
• The kidneys are involved in functions like filtration, producing erythropoietin etc., not insulin/glucagon production.
• Question 14:
• Cortisol is a glucocorticoid hormone (so A is true).
• It has gluconeogenic effects, which tend to elevate blood glucose levels (so B is true).
• It is synthesized in the adrenal cortex (so C is true).
• The fight - flight response is mainly stimulated by epinephrine and norepinephrine from the adrenal medulla, not cortisol (so D is not true).

Answer:

• Question 13: A. the pancreas
• Question 14: D. cortisol stimulates the fight - flight response.
