Document Summary
Lecture 14: the control of breathing (continued: summary of the control of breathing. Breathing is produced in the respiratory control centres of the medulla oblongata and the pons, in the brainstem. We are not particularly concerned with the receptors in the muscles and joints, but in short, while we all know that breathing increases during exercise, there is no known respiratory control system that can account for the increase. It is thought that this increase in breathing may actually be caused by mechanoreceptors or proprioceptors, rather than receptors that are specifically respiratory-related in nature: the pontine respiratory group (prg) The pontine respiratory group (prg) is located in the pons. It consists of two main nuclei, the k lliker fuse and the nucleus parabranchialis. It plays an important role in the termination of inspiration and the correct switching from inspiration to expiration.
