Study Notes
Respiratory System
- The diaphragm separates the thoracic cavity from the abdomen and serves as the primary muscle of inspiration, contracting and relaxing to facilitate breathing.
Thoracic Cage
- The thoracic cage, formed by the sternum, ribs, and thoracic vertebrae, provides a skeletal and soft tissue framework that protects the heart, lungs, and major blood vessels.
Thoracic Cage Function
- The main function of the thoracic cage is to protect the organs within it and provide a flexible yet durable enclosure that allows for expansion and contraction during breathing.
Costovertebral Joints
- The ribs articulate with the corresponding thoracic vertebrae and the vertebra above, forming costovertebral joints that provide flexibility and support to the thoracic cage.
