11. Acetylcholine is both an excitatory and inhibitory ligand depending on the location of its receptor. What does Acetylcholine do that makes it "excitatory"?
a. It causes a cell membrane to depolarize and produce Excitatory Post Synaptic Potentials
b. It opens K+ ion channels when it binds to its receptors
c. It causes a cell membrane to hyperpolarize
12. The bonding of Acetylcholine to its muscarinic receptors on smooth muscle causes gated K+ channels to close. This action is described as ___________________.
a. Excitatory as the cell membrane hyperpolarizes
b. Excitatory as the cell membrane depolarizes
c. Inhibitory as the cell membrane hyperpolarizes
13. Which voluntary division of the efferent (motor) nervous system stimulates skeletal muscle?
a. The somatic nervous system
b. The parasympathetic nervous system
c. The sympathetic nervous system
14. During the fight and flight response, elevated levels of epinephrine and norephinephrine stimulate less sensitive alpha receptors as well as beta receptors on smooth muscle of blood vessels. How does this impact blood flow?
a. Blood flow is redirected from skeletal muscle to the GI tract
b. Blood flow is redirected from the GI tract and kidneys to skeletal muscle
c. Blood flow is redirected from skeletal muscle to both the kidneys and GI tract
15. Which of the following are Adrenergic receptors?
a. Nicotinic receptors
b. Muscarinic receptors
c. Alpha and beta receptors

While walking to work, Mio has a sudden onset of dizziness and
feels faint. In addition, she experiences diaphoresis (excessive
sweating) and palpitations (rapid, fluttering heart). When she
arrives at her office, her concerned colleagues call an
ambulance.
In the emergency department, the nurse and doctor make the
following notes in Mio’s record:
55-year-old female, blood pressure = 162/110 mm Hg, on
metoprolol, furosemide, propafenone.
Blood pressure dropped upon standing to 102/65 mmHg, and
palpitations were observed.
