The hip is an example of which of the following type of joints?
A.
Ball-and-socket
B.
Pivot
C.
Gliding
D.
Hinge
The hip joint is an example of:
A. Ball-and-socket
Explanation:
- A. Ball-and-socket: The hip joint is classified as a ball-and-socket joint. This type of joint allows for a wide range of motion in several directions. The ball-shaped head of the femur fits into the socket of the acetabulum in the pelvis, enabling rotational movement and flexibility.
- B. Pivot: A pivot joint allows for rotational movement around a single axis. An example is the joint between the first and second cervical vertebrae (atlas and axis), which enables head rotation.
- C. Gliding: Gliding joints allow bones to slide past one another. These joints are found in areas such as the wrists and ankles, where the movement is primarily limited to sliding.
- D. Hinge: A hinge joint allows movement in one direction, similar to the opening and closing of a door. Examples include the elbow and knee joints.
Therefore, the correct classification for the hip joint is:
A. Ball-and-socket
