Question

A gliding joint is present between the

• A. Carpals
• B. Humerus and Glenoid cavity
• C. Carpal and Metacarpal of thumb
• D. Knee

Answer 1

The correct option is A

Carpals

The correct option is A.

Explanation of correct option:

Option A:

1. A gliding joint is a joint or connection between the ends of bones (articular surface) that are flat.
2. Due to the flat ends of bones, they can slide past one another.
3. A gliding joint is present between joints of carpals (wrist bones).
4. Other examples of a gliding joint are intermetacarpal joints, spine, etc.

Explanation of incorrect options:

Option B:

1. The humerus (upper arm bone) forms a ball and socket joint with the glenoid cavity (depression which articulates with the humerus).
2. A ball and socket joint consists of a bone with a round end inside a depression allowing movement in many planes as the ball rotates around the socket.

Option C:

1. A saddle joint is present between the carpals and metacarpals of the thumb.
2. Carpals are bones of the wrist, and metacarpals are bones of the palm.
3. A saddle joint is a type of synovial joint consisting of bones that run past each other and are filled with synovial fluid.
4. Saddle joints permit movements like extension and flexion and adduction and abduction but don't allow axial rotation.

Option D:

1. The knee joint is present between the Femur (thigh bone) and Tibia (shin bone).
2. It is a hinge joint.
3. It is also a synovial joint that primarily allows movement in one plane, similar to a hinge.

Final answer: A gliding joint is present between the carpals.
