Answer to Question 1

Correct Answer: 1,2,3,4
Rationale 1: The brain, spinal cord, and peripheral nerves act as a smoothly integrated whole to accomplish minute-to-minute changes in essential functions such as heart rate.
Rationale 2: The brain, spinal cord, and peripheral nerves act as a smoothly integrated whole to accomplish minute-to-minute changes in essential functions such as blood pressure.
Rationale 3: The brain, spinal cord, and peripheral nerves act as a smoothly integrated whole to accomplish minute-to-minute changes in essential functions such as pupil size.
Rationale 4: The brain, spinal cord, and peripheral nerves act as a smoothly integrated whole to accomplish minute-to-minute changes in essential functions such as intestinal motility.
Rationale 5: Although the brain, spinal cord, and peripheral nerves act as a smoothly integrated whole to accomplish minute-to-minute changes in essential functions, fluid volume is not under the control of the nervous system.

Answer to Question 2

Correct Answer: 3
Rationale: Adrenergic antagonists inhibit the actions of the sympathetic nervous system. They are also known as sympatholytics. They block adrenergic receptors, not cholinergic receptors.
