MSN 570 Patho Midterm Exam Review questions
with answers
respiratory zone - CORRECT ANSWERS ✔✔respiratory bronchioles, alveolar ducts,
alveoli
What does the Respiratory Zone do? - CORRECT ANSWERS ✔✔Allow inhaled
oxygen to diffuse into the lung capillaries in exchange for CO2
Conducting Zone - CORRECT ANSWERS ✔✔nose, pharynx, larynx, trachea,
bronchi, bronchioles
What does conducting zone do? - CORRECT ANSWERS ✔✔conducts air to
respiratory zone, humidifies, warms, and filters air
Most common cancer mutation? - CORRECT ANSWERS ✔✔Acquired
What does anticholinergic mean? - CORRECT ANSWERS ✔✔blockade of
muscarinic receptors - This inhibits nerve impulses responsible for involuntary
muscle movements and various bodily functions
What does dopamine do? - CORRECT ANSWERS ✔✔influences movement,
learning, attention, and emotion. Dopamine enables neurons in your brain to
communicate and control movement.
, What does messenger RNA do? - CORRECT ANSWERS ✔✔Transcribes information
from the DNA in the nucleus and carries it to the cytoplasm, and then to the
ribosome. Single-stranded, intermediate molecule. Carries the instructions for
making proteins.
What do ribosomes do? - CORRECT ANSWERS ✔✔Make proteins (protein
synthesis)
Neurotransmitters - CORRECT ANSWERS ✔✔chemical messengers that cross the
synaptic gaps between neurons
Neurotransmitters at the parasympathetic postganglionic synapses - CORRECT
ANSWERS ✔✔Acetylcholine and nitric oxide
Atropine Neurotransmitters - CORRECT ANSWERS ✔✔Atropine is a muscarinic
receptor antagonist that is used to inhibit the effects of excessive vagal activation on
the heart, which is manifested as sinus bradycardia and AV nodal block. Therefore,
atropine can temporarily revert sinus bradycardia to normal sinus rhythm and
reverse AV nodal blocks by removing vagal influences.
alpha adreneric receptors - CORRECT ANSWERS ✔✔
Beta-adrenergic receptor blockers - CORRECT ANSWERS ✔✔-Blocks NE/Epi effects
on heart - less Ca++ entry
-Decreases force of cardiac contractions
What do anticholinergics do? - CORRECT ANSWERS ✔✔Decrease the activity of
acetylcholine (neurotransmitter that regulates movement)
