Upper Limb – Additional Structures

Overview

Beyond muscles and bones, several specialised structures contribute to the fine control and stability of the upper limb. This section introduces the connective and supporting tissues that enhance precision and dexterity.

Key Structures

Articles include the anatomy of the nail unit, extensor tendon expansion, flexor pulley system, and the fascia and ligaments of the hand. Each topic details structural organisation and its role in movement efficiency.

Clinical Relevance and Learning Focus

Understanding these smaller but significant anatomical components is key for diagnosing hand injuries, tendon disorders and surgical repair planning. The section bridges micro-anatomical detail with functional and clinical relevance.
