Final answer:
Ulnar deviation is the term for the lateral movement of the wrist in anatomical position, moving towards the ulnar side of the forearm.
Step-by-step explanation:
In the anatomical position, the lateral movement of the wrist is known as ulnar deviation. Ulnar deviation occurs when the hand moves towards the ulnar side of the forearm. This movement is opposite to radial deviation, which is when the hand moves towards the radial side of the forearm.
