Answer 1

Hint: For all the types of movements and locomotion involving the bony parts of the body joints are essential. Joints are the point where the two bones or a bone and a muscle articulates (meets). The joints can be classified on the basis of structure and function. On the structural basis, joints are classified into fibrous, cartilaginous and synovial joints whereas in the functional basis they are classified into ball and socket, hinge joint, pivotal joint, saddle joint, condyloid joint and gliding joint.

Complete Step by Step Answer:
Fibrous joints are the immovable joints that are present where bones are not flexible such as upper jaw, ribcage, pelvic bone and the backbone. Cartilaginous joints are partly movable when the bones involved are joined together with the help of cartilage (slightly pliable matrix). It permits limited movement. Some examples are the spinal column and the ribcage. Synovial joints allow a considerable amount of movement and are characterised by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. The joints are classified on the basis of function and are freely movable joints. The ball and socket joints are present between humerus and the pectoral girdle, hinge joint is present in the knee joint, the pivot joint is present between the atlas and axis, gliding joint is present between the carpals whereas saddle joint in present between carpal and metacarpals.

Thus, the correct answer is option D


Note: Other examples of functional joints are condyloid joints which are present between the two axis and provide up-down or side to side motion and gliding joints which are a type of synovial joint that permits two or more round or flat bones to move together without any rubbing or crushing of bones.
