Dyspnea mechanisms Flashcard Deck - 10 Cards
Flashcard 1: Obstructive lung diseases are characterized by a(n) _____ total lung capacity
Answer: increased
Flashcard 2: Peripheral chemoreceptors ALSO respond to increases in _____
Answer: Pco2
Flashcard 3: Lung stretch receptors cause a(n) _____ breathing frequency in response to distention of the lungs (Hering-Breuer reflex)
Answer: decreased
Flashcard 4: _____ receptors are mechanoreceptors located in the smooth muscle of the airways
Answer: Lung stretch
Flashcard 5: The dorsal respiratory group receives sensory input from lung stretch receptors via the _____ nerve
Answer: vagus (CN X)
Flashcard 6: How does hyperventilation affect ICP?
Answer: low PCO2 leads to less cerebral blood flow, reducing ICP
Flashcard 7: In what situations is hyperventilation therapuetic?
Answer: increased ICP
Flashcard 8: What type of cytoskeletal element is most associated with flagella?
Answer: microtubules
Flashcard 9: What type of cytoskeletal element is most associated with cilia?
Answer: microtubules
Flashcard 10: Explain the substructure of cilia.
Answer: 9 microtubule doublets + 2 solitary microtubules (9+2 arrangement) with dyenin arms that link peripheral doublets
