MSN 570 Patho Midterm Exam Review Questions
and answers latest update 2024
respiratory zone
respiratory bronchioles, alveolar ducts, alveoli
What does the Respiratory Zone do?
Allow inhaled oxygen to diffuse into the lung capillaries in exchange for CO2
Conducting Zone
nose, pharynx, larynx, trachea, bronchi, bronchioles
What does conducting zone do?
conducts air to respiratory zone, humidifies, warms, and filters air
Most common cancer mutation?
Acquired
What does anticholinergic mean?
blockade of muscarinic receptors - This inhibits nerve impulses responsible for involuntary muscle
movements and various bodily functions
What does dopamine do?
influences movement, learning, attention, and emotion. Dopamine enables neurons in your brain to
communicate and control movement.
What does messenger RNA do?
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?
Make proteins (protein synthesis)
Neurotransmitters
chemical messengers that cross the synaptic gaps between neurons
Neurotransmitters at the parasympathetic postganglionic synapses
Acetylcholine and nitric oxide
Atropine Neurotransmitters
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.
