Control of Breathing Flashcards
1
Q
Components for Control of Breathing
A
Cerebral Cortex Control Centers in the Midbrain and Pons Central and Peripheral Chemoreceptors Mechanoreceptors Respiratory Muscles
2
Q
Creates the basic respiratory rhythm
A
MEDULLA
Dorsal Respiratory Group
Ventral Respiratory Group
Central Chemoreceptors
3
Q
Modifies the basic respiratory rhythm
A
PONS
Apneustic Center - LOWER pons
Pneumotaxic Center - UPPER pons
4
Q
Central Chemoreceptors
A
VENTRAL medulla
responds directly to CSF H+ (low pH in CSF)
d.t. high PaCO2
causes INCREASED RR
5
Q
Peripheral Chemoreceptors
A
responds MAINLY to HYPOSEMIA (PaO2 <60 mmHg)
high PaCO2
