MICROANATOMY

Detailed explanation-1: -The hip joint and the glenohumeral (shoulder) joint are the only ball-and-socket joints of the body. At the hip joint, the head of the femur articulates with the acetabulum of the hip bone, and at the shoulder joint, the head of the humerus articulates with the glenoid cavity of the scapula.

Detailed explanation-2: -Knees, elbows, and shoulders are examples of synovial joints. Since they allow for free movement, synovial joints are classified as diarthroses. Figure 38.10. 1: Synovial Joints: Synovial joints are the only joints that have a space or “synovial cavity” in the joint.

Detailed explanation-3: -A ball and socket joint is a synovial joint, which means it allows for smooth movements between bones. The end of one bone within the joint is spherical, forming the ball, while the end of the other bone within the joint contains a rounded depression, forming the socket.
