Spherical joints, also known as ball-and-socket joints, are a type of synovial joint that allows for a wide range of motion. They consist of a spherical head of one bone fitting into a cup-like socket of another bone. This design enables movements in multiple directions, including rotation, flexion, and extension. Common examples of spherical joints include the shoulder joint and the hip joint. These joints are crucial for various activities, providing flexibility and stability. The structure of spherical joints is supported by ligaments and cartilage, which help reduce friction and absorb shock during movement. Their unique design allows for greater mobility compared to other joint types, such as hinge joints.
