- Question 5
A rise in blood glucose levels triggers release of insulin from the pancreas. This mechanism of hormone production is stimulated by:

negative stimuli
neural stimuli
humoral stimuli
- Question 6
A scientist hypothesizes that the pancreas’s hormone production is controlled by neural stimuli. Which
observation would support this hypothesis?
Insulin is produced in response to sudden stress without a rise in blood glucose.
Insulin is produced in response to a rise in glucagon levels.
Beta cells express epinephrine receptors.
Insulin is produced in response to a rise in blood glucose in the brain.
- Question 7
Which mechanism of hormonal stimulation would be affected if signaling and hormone release from the hypothalamus was blocked?
humoral and hormonal stimuli
neural and humoral stimuli
hormonal and negative stimuli
hormonal and neural stimuli
