👉 A diaphragm is a muscular structure that connects two parts of the thoracic cavity (the chest) and separates it from the abdomen. It consists of four muscle groups, each with its own unique function:
1.
Cervical Diaphragm
: This group is responsible for moving the chest up and down, allowing the lungs to expand and contract.
2.
Thoracic Diaphragm
: This group is responsible for lifting the thorax upwards, while also preventing it from falling back
