Lecture 14: Neural Control Of Breathing Flashcards
1
Q
Which two cranial nerves send information from the peripheral chemoreceptors to the NTS?
A
Glossopharyngeal and Vagus.
2
Q
Are peripheral chemoreceptors predominantly involved in detecting oxygen or carbon dioxide?
A
Oxygen but can also detect carbon dioxide.
3
Q
What are central chemoreceptors involved in detecting?
A
Only carbon dioxide.
4
Q
Is oxygen or carbon dioxide responsible for moderating breath by breath modulation?
A
Carbon dioxide.
5
Q
Where are central chemoreceptors located?
A
Brainstem.
6
Q
Which cranial nerve sends information to the NTS from mechanoreceptors?
A
Vagus.
7
Q
What does NTS stand for?
A
Nucleus Tractus Solitarius.
8
Q
Do pattern generating neurons stimulate rhythm generating neurons or the other way around?
A
The other way around. Rhythm stimulates pattern.
