Question

Which of the following type of movement is supported by joints?

• A. Bending
• B. Partial rotation
• C. Complete rotation
• D. All of the above

Answer 1

Answer: (D)

There are various types of joints in the human body.

1. Hinge joint: Hinge joint is a common class of synovial joint that includes the ankle, elbow and knee joints. Maximum rotation is 180${}^o$. (partial rotation)

2. Ball and socket joints provide maximum rotation i.e. a full circle (complete rotation). Example: Shoulder joint, hip joint

3. The joints of the vertebrae provide a scope for bending movement, such joints are partially movable i.e. diarthrosis joints.

Thus, the types of movements supported by the joints are bending, partial rotation and complete rotation.
