Joints are the points where two or more bones meet, allowing for movement and flexibility in the body. They are classified into three main types based on their structure and function: fibrous, cartilaginous, and synovial joints. Fibrous joints, such as sutures and syndesmoses, are held together by dense connective tissue and do not allow for movement. Cartilaginous joints, like the epiphyseal plates in growing bones, are connected by cartilage and allow for limited movement. Synovial joints, the most common type, are characterized by a joint cavity filled with synovial fluid, which lubricates the joint and reduces friction during movement. Examples of synovial joints include the knee, hip, and elbow. Synovial joints are further classified into six types based on their structure: plane, hinge, pivot, condyloid, saddle, and ball-and-socket joints. Each type of joint plays a crucial role in the body's mobility and overall function.
