Dorsal Respiratory Group
Located in the Medulla - Causes inspiration when stimulated - (Timing) Normal, resting respirations. Rhythmic, mechanical pattern
Ventral respiratory Group
Located in the Medulla - Causes forced expiration or inspiration - (Timing) Speech, increased emotional or physical stress
Located in the Pons - Inhibits the DRG; increases speed and depth of respirations
Located in the Pons - Excites the DRG; prolongs inspiration, decreases rate
Hering-Breuer inflation reflex
Located in the Chest - Detects lung expansion to a point and then tells VRG and pneumotaxic and apneustic centers to stop
Hering-Breuer deflation reflex
Located in the Chest - Detects potential lung collapse and then tells VRG, pneumotaxic, and apneustic centers to stop
keeps you breathing so you do not have to think about it
(True or False) Both areas of the Pons are used to help augment respirations during emotional and physical stress
