Answer 0

Beta 2 agonist
Bronchial dilator
Albuterol

Question 1

Symptholytic

Answer 1

Beta blocker
Antihypertensive
Propranolol

Question 2

Parasympathomimetic

Answer 2

Muscarinic agonist
Decreases pressure in glaucoma
Pilocarpine

Question 3

Parasympatholytic

Answer 3

Muscarinic antagonist (block receptors on cardiac muscle)
Dilates eyes
Atropine

Question 4

Agonist

Answer 4

Bind to and cause response

Question 5

Mimetic

Answer 5

Mimic

Question 6

Ringer’s Solution

Answer 6

110 mM NaCl

2. 5 mM KCl
3. 0 mM CaCl2

Question 7

ACh (acetylcholine)

Answer 7

Decreased heart rate
Reduces slope of pacemaker potential via permeability changes
Parasympathetic neurotransmitter (inhibiting receptors)

Question 8

Epinephrine

Answer 8

Increased heart rate
Increases slope of pacemaker potential via permeability changes
Sympathetic neurotransmitter

Question 9

Atropine

Answer 9

Increase heart rate
Blocks ACh receptors
Parasympatholytic (block)

Question 10

Pilocarpine

Answer 10

Decreased heart rate
Enhances release of ACh
Parasympathomimetic

Question 11

Propranolol

Answer 11

Decreased heart rate
Beta blocker
Sympatholytic (correct heart beat)

Question 12

Digitalis

Answer 12

Decreased heart rate, strengthen contractions
Inhibits Na/K pump and enhances Ca++ entry
Cardiac glycoside used to control atrial fibrillation

Question 13

KCl

Answer 13

Decreased heart rate, cardiac arrest
Depolarizes membranes
Dr. Kevorkian’s machine, lethal injection

Question 14

NaCl

Answer 14

Erratic results
Unusual ion ratios affect membrane potential and calcium influx
Similar to Ringers solution but lacks K+ and Ca++

Question 15

CaCl2

Answer 15

Increased force of contractions but may be erratic
Increased intracellular availability of Ca++
Calcium binds to Troponin-C and activates the thin filaments

Question 16

Procedure

Answer 16

ACh
Atropine
Propranolol 
Epinephrine 
Verapamil
KCl
