Which joint type is primarily found in the wrist, allowing for limited movement in two planes?

The condyloid joint, also known as an ellipsoidal joint, is the correct answer because it permits movement in two planes: flexion and extension as well as abduction and adduction. This type of joint features an oval-shaped end of one bone fitting into a similarly shaped cavity of another bone, allowing for this limited range of motion. In the wrist, the radiocarpal joint is a prime example of a condyloid joint, enabling movements such as the up-and-down motion of the wrist as well as the sideways movement.

The other joint types do not fit this description. Pivot joints allow for rotation around a single axis, which is limited to movements like turning the head. Hinge joints permit movement primarily in one plane, mainly flexion and extension, as seen in the elbow. Ball and socket joints provide the most extensive range of motion, allowing movement in multiple directions and are exemplified by the hip and shoulder joints.
