A scientist hypothesizes that the pancreas’s hormone production is controlled by neural stimuli. Which observation would support this hypothesis? a. Insulin is produced in response to sudden stress without a rise in blood glucose. b. Insulin is produced in response to a rise in glucagon levels. c. Beta cells express epinephrine receptors. d. Insulin is produced in response to a rise in blood glucose in the brain.
Even though they are not a hormone, prostaglandins act in a similar way. Shortly answer the following question according to the diagram.
1.Do the prostaglandins serve as a hormonal control system? If so, identify that system and explain your answer.
