respiratory control of breathing

Question 1

What are the location of regulation of breathing?

Answer 1

1. Cortex
2. pons
3. arterial/central chemoreceptors- reflex

Question 2

what are the stimuli and how do they manipulate the respiritory center?

Answer 2

1. central and peripheral chemoreceptors monitor blood gases and pH
2. Voluntary control
   
   1. exerted by the cerbral cortex

Question 3

a patient was in a bad accident and is currently in a coma, the damage was above the brainstem. What could you expect the breathing to be?

Answer 3

higher centers and cerbrum can alter breathing, but ARE NOT REQUIRED

-as long as the damage is above the pons, respiration is basically normal

Question 4

Is it possible for an emotional experience to overide a chemoreceptor reflex?

Answer 4

no, consciously alter pattern temporarily but CAN NOTover ride chemoreceptor reflexes

example: voluntary breath holding (hypoventiliation)

Question 5

explain the concept behind free diving

Answer 5

a period of prior hyperventilation decreasing the PaCO2 (increasing the pH) which can’t be sustained, but can prolong the duration of breath-holding.

Question 6

respiratory system is under what type of control

Answer 6

somatic and autonomic

Question 7

where are they and what do the peripheral chemoreceptors detect changes in?

Answer 7

Carotid bodies and aortic bodies- close to mechanos receptors

Detect changes in plasma

1. PO2
2. pH
3. PCO2
   4.
