The wrist joint is a complex structure that connects the forearm to the hand. It consists of several small bones, including the carpals, which allow for a wide range of motion. This joint enables movements such as flexion, extension, and rotation, making it essential for daily activities like writing and typing. The wrist joint is supported by ligaments and tendons that provide stability and strength. It is also surrounded by synovial fluid, which lubricates the joint and reduces friction during movement. Proper function of the wrist joint is crucial for overall hand dexterity and functionality.
