What type of joint is referred to as a symphysis?
A joint formed by synovial fluid
A joint joined by fibrocartilage
A hinge joint
A ball-and-socket joint
The correct answer is: A joint joined by fibrocartilage
A symphysis is characterized as a type of joint in which two bones are connected by a pad of fibrocartilage. This structure allows for limited movement, which is essential in certain areas of the body, such as the pubic symphysis in the pelvis and the intervertebral discs of the spine. The fibrocartilage provides cushioning and support, enabling the joint to absorb shock and facilitate slight movement between the joined bones, which is important for maintaining flexibility and stability in areas that undergo stress or pressure. This definition distinguishes a symphysis from other types of joints, such as synovial joints, which are lubricated by synovial fluid, hinge joints, which allow movement in one direction, and ball-and-socket joints, which enable a wider range of motion.
