Chapter 21, Problem 18CYR
Summary Introduction

Introduction:

The ventilation carried out by the respiratory system is largely under the control of the brainstem. There are certain collections of neurons that generate the rhythm for breathing and are called the respiratory pattern generators. These are of two main population types, namely, the dorsal respiratory group (DRG) and the ventral respiratory group (VRG).
