Respiratory control centers in the brain

What two centers control respiration in the medulla and the pons?

- Respiratory rhythmicity centers - Apneustic and Pneumotaxic centers

What is the function of the Pneumotaxic center?

A nuronal network that inhibits the activity of neurons in the dorsal respiratory group, allowing for relaxation after inhalation, thus controlling overall rate of respiration

What is pneumothorax?**

Air within the interpleural space resulting in an increased pressure on the outer surface of the lungs which can cause the lung to collapse

What respiratory center(s) are located in the pons?

Apnuestic and pneumotaxic centers

What is the function of the respiratory rhythmic center and where is it located?

Medulla oblongata Function: pacemaker to establish basic pace of breathing

What is the function of the dorsal respiratory group (DRG)?

Pacemaker; These are neurons are involved in maintaining a constant breathing rhythm by stimulating diaphragm to and external intercostal muscles to contract resulting in inhalation; When DRG relaxes exhalation occurs

What respiratory center is located in the medulla oblongata?

Respiratory rhythmic centers

What is the function of the apneustic and pnemotaxic centers?

They adjust the output of the respiratory rhythmic centers

What is the function of the Apneustic center?

double cluster of cell bodies that stimulate nuerons in the dorsal respiratory group controlling depth of inhalation, specifically for deep breathing

What is the function of the ventral respiratory group?

involved in forced breathing as neurons stimulate accessory muscles resulting in both forced inhalation and exhalation

What OVERALL regulates the respiratory rate and depth?**

medulla oblongata and pons

What 2 groups of neurons are part of the respiratory rhythmicity centers located in the medulla oblongata?*

- Dorsal respiratory group - Ventral respiratory group

Where are the two respiratory centers located in the brain?

- Medulla Oblongata - Pons
