How many rows of bones make up the carpals in the wrist?

The structure of the carpal bones in the wrist consists of two rows, each containing four bones. This arrangement provides both stability and a degree of flexibility to the wrist, allowing for a wide range of motion. The first row, known as the proximal row, consists of the scaphoid, lunate, triquetrum, and pisiform bones. The second row, or distal row, includes the trapezium, trapezoid, capitate, and hamate bones. This two-row configuration is a fundamental aspect of wrist anatomy and is essential for understanding the mechanics of hand and wrist movement.
