Respiratory Physiology VI Flashcards
1
Q
Brainstem control of regulation
A
inspiratory center
pneumotaxic center
apneustic center
2
Q
Joint and muscle stretch receptor function
A
monitoring of limb movement and breathing effort
3
Q
Central and peripheral chemoreceptors
A
monitoring of CO2, pH, and O2
4
Q
Pulmonary stretch and irritant receptors
A
detects degree of stretch of lung parenchyma
detect irritants in the airways
5
Q
Which cranial nerves affect the inspiratory center?
A
CN 9 and 10
6
Q
How do peripheral chemoreceptors respond to pH?
A
- detect O2, CO2, and H+
- increase breathing rate by decreasing O2, increasing CO2, or increasing H+
7
Q
How are pulmonary mechanoreceptors activated?
A
By distention of the airways and lungs, they initiate a reflex decrease in breathing rate
