dorsal respiratory group
apneustic center
Portion of the pons that increases the length of inspiration and decreases the respiratory rate. Prolonged inspirations can result from stimulating which center? sends stimulatory impulses to the medullary inspiratory center causing prolonged inspiratory efforts that result in deeper, slower breathing stimulates dorsal respiratory group, longer slower respirations
dorsal respiratory group
Which area of the brain stimulates the diaphragm to contract to initiate inspiration? respiratory rhythm center located in the brainstem that controls the rate of depth of normal quiet respiration neurons in the medullary respiratory center that fire during inspiration **** This respiratory neuron group regulates inspiration at rest, is located within the medulla, and sends signals to the diaphragm.
pneumotaxic center
area of the upper pons in the brain that modulates activity of the apneustic center what is "Switch-off"" center, regulating rate and depth of pulmonary filling pontine respiratory center; this innervates the DRG **upper pons, inhibits inspiration, regulates volume and respiratory rate ***** area of the brain that triggers the cessation of breathing, regulating inhalation such that the lungs do not over-inflate
ventral respiratory group
what stimulates the contraction of internal intercostals and ab muscles (forced expiration)? Expiration; not active during normal, quiet breathing helps provide for forced inspiration or expiration as needed one of the main complexes of neurons in the medullary respiratory center **** Controls voluntary forced exhalation and acts to increase the force of inspiration. Regulates rhythm of inhalation and exhalation.
