Wrist joint

The **wrist joint** is a complex anatomical structure in the human upper limb, comprising articulations between the radius, ulna, and the eight carpal bones. The main wrist (radiocarpal) joint is a synovial, condyloid-type joint formed by the distal end of the radius and an articular disc, articulating with the proximal row of carpal bones (scaphoid, lunate, and triquetrum) [4][8]. Additional associated joints include the midcarpal joint (between the carpal rows) and the distal radioulnar joint (between radius and ulna) [1][2][3]. These joints are stabilized by a complex system of ligaments and are capable of movements including flexion, extension, radial and ulnar deviation, pronation, and supination [1][4]. The wrist is essential for manual dexterity, hand function, and load transmission from the hand to the forearm [2][5][7]. "Wrist joint" is not a molecule or molecular therapeutic target, but rather an anatomical region consisting of multiple joints and associated soft tissue structures [1][2][4][5][7]. **Explanation:** "Wrist joint" refers to a region and specific anatomical joints, not a molecular or pharmacological target (receptor, enzyme, transporter, etc.). It is not appropriate for the studied molecular classifications, mechanisms of action, or drug interactions, and therefore is marked as incorrect for this context.
