The wrist represents one of the most complex joint systems in the human body, facilitating a remarkable range of motion crucial for daily activities and specialized tasks. The anatomical illustration demonstrates the dynamic positioning of carpal bones during two fundamental wrist movements: dorsiflexion (extension) on the left and palmar flexion on the right. This sagittal view provides critical insight into how individual carpal bones articulate and reposition during these opposing movements.

The human hand is a remarkable feat of anatomical engineering, comprising 27 bones that work in concert to provide the intricate movements essential for daily activities. This comprehensive guide explores the detailed anatomy of hand bones, their relationships, and clinical significance in medical practice. Understanding hand bone anatomy is crucial for healthcare professionals, particularly in diagnosing and treating hand injuries and pathologies.
