Which bony landmark is activated through flexion and ulnar deviation of the hand? A) Tubercle of the Scaphoid B) Lunate C) Capitate D) Pisiform
Understand the Problem
The question is asking about a specific anatomical landmark that becomes engaged during the flexion and ulnar deviation movements of the hand. It seeks to identify which of the given options applies to these actions.
Answer
Tubercle of the Scaphoid
The bony landmark activated through flexion and ulnar deviation of the hand is the Scaphoid, specifically its tubercle.
Answer for screen readers
The bony landmark activated through flexion and ulnar deviation of the hand is the Scaphoid, specifically its tubercle.
More Information
The scaphoid bone, particularly its tubercle, is important in wrist mechanics and can be more prominent or activated during certain movements like flexion and ulnar deviation.
Tips
Mistaking which wrist movements affect which carpal bones can lead to incorrect identification.
