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

Questions With 100% Verified Answers
What does messenger RNA do? - correct 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? - correct answer ✅Make proteins (protein
synthesis)
Neurotransmitters - correct answer ✅chemical messengers that
cross the synaptic gaps between neurons
Neurotransmitters at the parasympathetic postganglionic synapses
- correct answer ✅Acetylcholine and nitric oxide
Atropine Neurotransmitters - correct 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.
alpha adreneric receptors - correct answer ✅
