Pneumotaxic center
Pneumotaxic Center
The Pneumotaxic Center (pronounced: noo-mo-tax-ik cen-ter), also known as the pneumotaxic nucleus or pontine respiratory group, is a network of neurons located in the upper part of the Pons, a region in the Brainstem.
Etymology
The term "Pneumotaxic" is derived from the Greek words "pneumo" meaning "lung" and "taxic" meaning "arrangement" or "order". This term reflects the center's role in regulating the pattern of breathing.
Function
The Pneumotaxic Center plays a crucial role in the regulation of respiration. It sends inhibitory impulses to the dorsal respiratory group (DRG) and the ventral respiratory group (VRG), two other important centers in the brainstem involved in controlling the rhythm of breathing. By inhibiting these centers, the Pneumotaxic Center helps to control the rate and depth of breathing, preventing over-inflation of the lungs.
