1
Q

What kind of control is respiration under?

A

Autonomic control

2
Q

Where is rhythm generated for respiration?

A

Rhythm is generated by the medulla specifically the Botzinger complex

3
Q

What does the Botzinger complex do?

A

They drive the respiratory motoneurons and interneurons of the spinal cord.

4
Q

What are two peripheral chemoreceptors?

A

Carotid and aortic

5
Q

Describe two features of the carotid peripheral chemoreceptor.

A
  • They are small nodules at the bifurcation of the common carotid
  • Dominant effect senses at low O2
6
Q

Where are aortic peripheral chemoreceptors found?

A

Aortic bodies are found in the aortic arch

7
Q

What stimulates the peripheral chemoreceptors?

A

Low partial pressure of oxygen & high partial pressure of carbon dioxide

8
Q

Which of the peripheral chemoreceptors responses to increased partial pressure of carbon dioxide and a decrease in pH. This peripheral chemoreceptor is also important in exercise and is the SOLE detector of arterial pH.

A

Carotid peripheral chemoreceptors

9
Q

What chemoreceptor is located close to the ventral surface of the medulla?

A

Central chemoreceptor

10
Q

How does a central chemoreceptor detect changes in the blood?

A

They bind protons in the brain they
