Multiple Choice

Each wrist contains how many carpal bones?

Previous problemNext problem

Verified step by step guidance

Begin by understanding the anatomy of the wrist, which is known as the carpus. The carpus is composed of several small bones that allow for a range of movements.

Identify the carpal bones, which are the small bones located in the wrist. These bones are arranged in two rows: a proximal row and a distal row.

Recall that the proximal row of carpal bones includes the scaphoid, lunate, triquetrum, and pisiform bones.

Remember that the distal row of carpal bones includes the trapezium, trapezoid, capitate, and hamate bones.

Count the total number of carpal bones in both rows. There are four bones in the proximal row and four bones in the distal row, making a total of eight carpal bones in each wrist.
