How many carpal bones are present in the wrist?

The human wrist is composed of eight carpal bones, which are organized in two rows of four bones each. These bones play a crucial role in wrist mobility and function, providing the necessary structure to support a wide range of movements. Each carpal bone contributes to the articulation with both the radius and the ulna of the forearm, as well as forming joints with each other and with the first row of metacarpal bones.

Understanding the anatomy of the carpal bones is important for Pilates instructors, as many exercises involve wrist stabilization and mobility. An awareness of these bones can inform safe practice and adjustments for clients, especially those with wrist issues or limited mobility.

The other options reflect incorrect quantities, as there are only eight carpal bones categorized into specific names: scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate. Each of these bones has a unique shape and function, further emphasizing the importance of recognizing the correct number of bones in this complex joint structure.
