In the hand, the thumb’s saddle joint (between the first metacarpal and the trapezium) lets the thumb cross over the palm, making it opposable. (6) The ball-and-socket joint is a freely moving joint that can rotate on any axis. The hip and shoulder joints are examples of ball and ...
At asaddle joint, both of the articulating surfaces for the bones have a saddle shape, which is concave in one direction and convex in the other (see Figure 3c). This allows the two bones to fit together like a rider sitting on a saddle. Saddle joints are functionally classified as biaxi...
saddle joint:synovial joint in which the articulating ends of both bones are convex and concave in shape, such as at the first carpometacarpal joint at the base of the thumb; functionally classified as a biaxial joint subacromial bursa:bursa that protects the supraspinatus muscle tendon and superi...
