|
||||
| show | Medullary Neurons
🗑
|
||||
| What are the 2 types of Medullary Neurons? | show 🗑
|
||||
| show | True
🗑
|
||||
| What is the purpose of DRG? | show 🗑
|
||||
| show | Function during exercise or disease to activate the accessory muscles.
🗑
|
||||
| show | To "BOOST" inspiratory effort, aka "Gasping Center"
🗑
|
||||
| show | Gasping Center
🗑
|
||||
| show | To increase rate & simultaneously decrease tidal volume, aka "Panting Center"
🗑
|
||||
| Pneumotaxic Center is aka as what? | show 🗑
|
||||
| Which nerve innervates the carotid peripheral chemoreceptors? | show 🗑
|
||||
| Which nerve innervates the aortic peripheral chemoreceptors? | show 🗑
|
||||
| What is the chemical stimuli of the Peripheral Chemoreceptors? | show 🗑
|
||||
| Peripheral Chemoreceptors kick in when? | show 🗑
|
||||
| show | At CO2 tensions & low pH H+
🗑
|
||||
| What is the chemical stimuli of the Central Chemoreceptors? | show 🗑
|
||||
| show | VE increases 3L/m for each mmHg rise in PACO2
🗑
|
||||
| What is the strongest stimulus to ventilation? | show 🗑
|
||||
| What are the factors which affect ventilatory response to CO2? | show 🗑
|
||||
| show | VE increase dramatically when PaO2 <60mmHg
🗑
|
||||
| show | Hypercapnia significantly augments the hypoxic response.
🗑
|
||||
| show | Hypocapnia significantly diminishes the hypoxic response.
🗑
|
||||
| show | Acute Acidosis stimulates Peripheral Chemoreceptors & VE increases. The lower the pH, the greater the VE increases.
🗑
|
||||
| show | Hypocapnia diminishes the ventilatory response to acidosis
🗑
|
||||
| show | Hypercapnia intensifies the ventilatory response to acidosis
🗑
|
||||
| What is the pH of CSF? | show 🗑
|
||||
| show | 1. Gasses like CO2 which diffuse across readily
2. Ions like H+, HCO3- active transport--slow process
🗑
|
