Explanation:
Detailed explanation-1: -The diaphragm is a thin dome-shaped muscle which separates the thoracic cavity (lungs and heart) from the abdominal cavity (intestines, stomach, liver, etc.).
Detailed explanation-2: -The diaphragm should be viewed as two distinct muscles, crural and costal, which act in synchrony throughout respiration. However, the activities of these two muscular regions can diverge during certain events such as swallowing and emesis.
Detailed explanation-3: -The diaphragm has a dome-like structure with the peripheral segment attached to the chest wall and abdominal cavity. The muscle fibers from these attachments converge in a central tendon, which forms the crest of the dome.
