Apneustic center

Apneustic Center

The apneustic center is a region of the brain that plays a crucial role in the control of respiration. It is located in the lower pons, a part of the brainstem, and is responsible for promoting inspiration by stimulating the neurons in the dorsal respiratory group.

Function

The primary function of the apneustic center is to control the intensity of breathing, adjusting the volume of the lungs during inspiration. It sends signals to the dorsal respiratory group, which in turn stimulates the muscles involved in inspiration, such as the diaphragm and the external intercostal muscles.

The apneustic center also receives inhibitory signals from the pneumotaxic center, another part of the brain involved in the regulation of respiration. This interaction helps to regulate the rate and depth of breathing, preventing over-inflation of the lungs.

Clinical Significance

Damage to the apneustic center can lead to apneustic breathing, a breathing disorder characterized by deep, gasping inspiration with a pause at full inspiration followed by a brief, insufficient release. This condition can be life-threatening and requires immediate medical attention.
