41.The joints found in bones of metacarpals and carpals of thumb are called as A. Ball and socket joint B. Saddle joints C. Hinge joints D. Pivot joint
Option B Joints are points of contact between bones, or between bones and cartilages. Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements. Saddle joint is a type of synovial joint. The saddle joint gets its name because the bone forming one part of the joint is concave (turned inward) at one end and looks like a saddle. The other bone's end is convex (turned outward), and looks like a rider in a saddle. The joint between carpal and metacarpal of human thumb is an example of saddle joint.
