Regulation of Hormone Production

Review Questions

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

  1. humoral stimuli
  2. hormonal stimuli
  3. neural stimuli
  4. negative stimuli

Hint:

A

Which mechanism of hormonal stimulation would be affected if signaling and hormone release from the hypothalamus was blocked?

  1. humoral and hormonal stimuli
  2. hormonal and neural stimuli
  3. neural and humoral stimuli
  4. hormonal and negative stimuli

Hint:

B

A scientist hypothesizes that the pancreas’s hormone production is controlled by neural stimuli. Which observation would support this hypothesis?

  1. Insulin is produced in response to sudden stress without a rise in blood glucose.
  2. Insulin is produced in response to a rise in glucagon levels.
  3. Beta cells express epinephrine receptors.
  4. Insulin is produced in response to a rise in blood glucose in the brain.

Hint:

A
