Introduction[edit | edit source]
Biomechanics is the study of forces and their effects when applied to human body. To understand the biomechanics of thorax we will need to study the basic anatomy, joint articulations, muscles associated in the thorax along with kinematics of the rib cage.
The thorax is formed by the thoracic vertebrae ,the ribs and the sternum. It has two main functions,
- Providing anchor for muscle attachments
- Role of ventilation
Structure of Thorax[edit | edit source]
This is the cornerstone of understanding function and thus biomechanics of thorax.

Articulations[edit | edit source]
- Manubriosternal and Xiphisternal Joints
- Costovertebral Joints
- Costotransverse Joints
- Costochondral and Costosternal Joints
- Interchondral Joints
