Which synovial joint describes the hip?

The synovial joint that describes the hip is called the hip joint. It is a ball-and-socket joint that connects the thigh bone (femur) to the pelvis (hip bone). The ball of the hip joint is formed by the head of the femur, while the socket is formed by the acetabulum, which is a cup-shaped depression in the hip bone. The hip joint is surrounded by a joint capsule and lined with a synovial membrane, which produces synovial fluid to lubricate the joint and reduce friction during movement. The hip joint allows for a wide range of movements, including flexion, extension, abduction, adduction, and internal and external rotation, which are essential for walking, running, and other physical activities.
