Can you provide details about the trapezoid and its anatomical significance?
Understand the Problem
The question involves information about specific bones, their anatomy, and associated muscular attachments. It's focusing on detailed anatomical knowledge regarding the carpal bones and their relationships.
Answer
Small carpal bone with a distal articular surface larger than the proximal. It articulates with the scaphoid, trapezium, second metacarpal, and capitate.
The trapezoid bone is situated in the distal row of carpal bones. It has a larger distal articular surface compared to its proximal surface and is prolonged laterally on its palmar, non-articular surface. The trapezoid articulates with the scaphoid, trapezium, second metacarpal, and capitate bones.
Answer for screen readers
The trapezoid bone is situated in the distal row of carpal bones. It has a larger distal articular surface compared to its proximal surface and is prolonged laterally on its palmar, non-articular surface. The trapezoid articulates with the scaphoid, trapezium, second metacarpal, and capitate bones.
More Information
The trapezoid bone, also known as the lesser multangular bone, is the smallest bone in the distal row of the carpal bones. It plays a role in wrist mobility and stability, serving as a crucial link in the carpal architecture.
Tips
Common mistakes include confusing the trapezoid with the similarly named trapezium or misunderstanding its position and articulations within the hand.
