Bones of the Thorax

Overview

The bony framework of the thorax protects vital organs and provides attachment points for respiratory muscles. This section introduces the main skeletal components and their roles in stability, protection and ventilation.

Key Structures

Topics include the ribs, sternum and thoracic spine, outlining their features, articulations and functional contributions to thoracic movement and respiration.

Clinical Relevance and Learning Focus

Knowledge of thoracic skeletal anatomy is important for assessing trauma, interpreting chest imaging and understanding respiratory mechanics. This section supports identification of fractures, deformities and degenerative changes.
