Apneustic center
Apneustic Center
The Apneustic Center (pronounced: ap-noo-stik sen-ter) is a region of the pons that plays a crucial role in the control of respiration.
Etymology
The term "Apneustic" is derived from the Greek word "apnoia", which means "want of breath". The term "center" is from the Latin "centrum", meaning "middle point".
Function
The Apneustic Center sends signals to the dorsal respiratory group in the medulla, promoting inspiration by stimulating the neurons that innervate the diaphragm and external intercostal muscles. It also inhibits the pneumotaxic center, another region of the pons that regulates the rate and pattern of breathing.
Clinical Significance
Damage to the Apneustic Center can result in apneustic breathing, a breathing disorder characterized by deep, gasping inspiration with a pause at full inspiration followed by a brief, insufficient release.
