1. Vasoconstriction is a _______________ response.
A) sympathetic
B) parasympathetic

2) What is the stimulus that causes depolarization of baroreceptors (i.e., specialized neurons that monitor pressure in major arteries)?
A) Binding of chemicals to ligand-gated channels in the baroreceptor membrane.
B) Binding of chemicals to mechanical-gated channels in the baroreceptor membrane.
C) Stretch of arterial walls that forces open ligand-gated channels in the baroreceptor membrane.
D) Stretch of arterial walls that forces open mechanical-gated channels in the baroreceptor membrane.

3) Which of the following events are considered visceral motor? Choose ALL that apply.
A) Increase of action potentials from baroreceptors to brain cardiovascular control centers
B) Release of acetylcholine from cardioinhibitory neurons
C) Neurons stimulating the release of epinephrine and norepinephrine to cause vasoconstriction
D) Communication between neurons WITHIN the cardiovascular control centers of the medulla (hindbrain)

4) An increase in cardiac output will help to lower blood pressure.
A)True
B)False

5) The visceral motor events completed (either sympathetic or parasympathetic) to help return the blood pressure to a homeostatic setpoint are part of ________________ feedback loops.
A)Negative
B)Positive
