What is the primary function of the carpal bones?

The primary function of the carpal bones is to facilitate movement of the wrist. The carpal bones, which consist of eight small bones located in the wrist region, are arranged in two rows and work together to form the complex structure of the wrist joint. This arrangement allows the wrist to perform a wide range of movements, including flexion, extension, and circumduction, which are essential for hand functionality.

The mobility provided by the carpal bones is crucial for various activities, such as grasping, lifting, and manipulating objects, making them fundamental to the overall dexterity of the hand. By allowing for these movements, the carpal bones play a key role in the biomechanics of the upper extremity, significantly contributing to the overall functionality of the arm and hand in everyday tasks.
