Question
Chapter 22, Problem 1RQ
Summary Introduction
To determine:
The event that occurs after the contraction of the inspiratory muscles.
Introduction:
The external intercostal muscles are attached to the walls of the thoracic cavity. Contraction or relaxation of these causes changes the volume of the thoracic cavity and lungs. There are changes in the rib cage as well as the dome-shaped diaphragm and finally in the pressure of air within the pleural cavity hence, completing the process of inspiration. The inspiratory muscles include a group of muscles associated with the breathing process.

When the inspiratory muscles contract, (a) only the lateral dimension of the thoracic cavity increases, (b) only the anteroposterior dimension of the thoracic cavity increases, (c) the volume of the thoracic cavity decreases, (d) both the lateral and the anteroposterior dimensions of the thoracic cavity increase, (e) the diaphragm bulges superiorly.
