MSN 570 Patho Midterm Exam Review
Questions with Correct Answers | Updated
(100% Correct Answers)
respiratory zone Answer: respiratory bronchioles, alveolar ducts,
alveoli
What does the Respiratory Zone do? Answer: Allow inhaled oxygen
to diffuse into the lung capillaries in exchange for CO2
Conducting Zone Answer: nose, pharynx, larynx, trachea, bronchi,
bronchioles
What does conducting zone do? Answer: conducts air to respiratory
zone, humidifies, warms, and filters air
Most common cancer mutation? Answer: Acquired
What does anticholinergic mean? Answer: blockade of muscarinic
receptors - This inhibits nerve impulses responsible for involuntary
muscle movements and various bodily functions
What does dopamine do? Answer: influences movement, learning,
attention, and emotion. Dopamine enables neurons in your brain to
communicate and control movement.

What does messenger RNA do? Answer: 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? Answer: Make proteins (protein synthesis)
Neurotransmitters Answer: chemical messengers that cross the
synaptic gaps between neurons
Neurotransmitters at the parasympathetic postganglionic synapses
Answer: Acetylcholine and nitric oxide
Atropine Neurotransmitters Answer: 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.
Beta-adrenergic receptor blockers Answer: -Blocks NE/Epi effects on
heart - less Ca++ entry
-Decreases force of cardiac contractions
What do anticholinergics do? Answer: Decrease the activity of
acetylcholine (neurotransmitter that regulates movement)
