MSN 570 Patho Midterm Exam Review ()
Questions and Verified Answers, 100% Guarantee Pass
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)
beta-adrenergic receptors - CORRECT ANSWER -Portions of the nervous system that, when
stimulated, can cause an increase in the force of contraction of the heart, an increased heart
rate, and bronchial dilation.
alpha-adrenergic receptors - CORRECT ANSWER -Portions of the nervous system that, when
stimulated, can cause constriction of blood vessels.
arachnoid meninges - CORRECT ANSWER -middle layer - network of fibers and collagen that are
part of the suspension system that helps protect the brain and spinal cord from sudden impact
