Which of the following is an example of a synovial joint?

The hip joint is indeed a prime example of a synovial joint. Synovial joints are characterized by their ability to allow a wide range of movement and are the most mobile type of joint in the human body. They are defined by their structure, which includes a joint capsule that encloses the joint, synovial fluid that lubricates the joint, articular cartilage that covers the ends of the bones, and ligaments that connect the bones and stabilize the joint.

The hip joint, specifically, is a ball-and-socket joint, allowing for movements in numerous directions, including flexion, extension, abduction, adduction, and rotation. This extensive mobility is crucial for activities such as walking, running, and jumping.

Other joints listed, such as the knee joint and wrist joint, are also synovial joints. The knee is a hinge joint, allowing primarily bending and straightening, while the wrist includes several types of synovial joints that permit various movements like flexion and extension, as well as some rotational movement. However, the skull joints, specifically the sutures, are not synovial joints; they are classified as fibrous joints and allow minimal to no movement.

In summary, the hip joint exemplifies
