Bones of the Upper Limb

Overview

The bony framework of the upper limb provides strength, support and leverage for movement. This section explores the osteology of the shoulder girdle, arm, forearm and hand, highlighting how structure relates to function.

Key Structures

Articles describe the detailed anatomy of each bone including the scapula, clavicle, humerus, radius, ulna and the bones of the hand. Key landmarks, articulations and muscle attachments are clearly illustrated to reinforce spatial understanding.

Clinical Relevance and Learning Focus

Understanding bone anatomy is crucial for recognising fractures, interpreting radiographs and performing orthopaedic procedures. The section links skeletal landmarks to clinical practice, helping learners visualise alignment, movement and injury mechanisms.
