wrist extension

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 forearm is a vital component of the upper limb, featuring a network of superficial muscles that drive wrist, hand, and finger movements. This article examines the anatomy of the left forearm superficial muscles from a dorsal perspective, as illustrated in the provided image, highlighting their origins, functions, and clinical importance. This detailed view serves as an essential guide for understanding the muscular structure that supports daily activities and informs therapeutic practices.

Explore the detailed anatomy of the posterior forearm bones, including extensor muscle attachments and grooves. Essential knowledge for medical professionals involved in upper limb assessment and surgical planning.
