Which of the following is an accurate difference between theeffects produced by the stimulation of alpha-1 receptors and of thebeta-2 receptors by epinephrine?

• The stimulation of alpha-1 receptors increases the release ofnorepinephrine, while the stimulation of beta-2 receptors decreasesthe release of norepinephrine.

• The stimulation of alpha-1 receptors stimulates cardiac muscle,while the stimulation of beta-2 receptors stimulates skeletalmuscle.

• The stimulation of alpha-1 receptors causes smooth musclecontraction, while the stimulation of beta-2 receptors causessmooth muscle relaxation.

• The stimulation of alpha-1 receptors stimulates skeletal muscleblood vessels, while the stimulation of beta-2 receptors stimulatesmuscles in arteries and veins.
