MSN 570 Patho Midterm Exam Review
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.
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
Beta-adrenergic receptor blockers - correct answer -Blocks NE/Epi effects on heart - less Ca++
entry
-Decreases force of cardiac contractions
What do anticholinergics do? - correct answer Decrease the activity of acetylcholine
(neurotransmitter that regulates movement)
Atropine - correct answer muscarinic antagonist (anticholinergic)
