Atlantoaxial-synovial; pivot. The joint between the atlas and axis is called the atlanto-axial joint. It is comprised of the anterior portion of the ring of C1 and the odontoid process (or dens) of C2.This joint allows for about 50 percent of the side to side rotation of the head.ry and shake your head no, this is due to the pivot joint of the two vertebrae! this joint also known as atoaxoid joint. pivot. it is called the atlanto-axial joint.

  Synovial joints allow for movement between the articulating bones (in this case the sternum and the clavicle). The articulating bones are covered in articular cartilage, â¦ which are connected with ligaments and lined with a synovial membrane.There is a fluid-filled sac between these types of joints to reduce the amount of friction with movement and the fluid inside of these sacs is called synovial fluid.he synovial joint is so called because the gap formed by the two articulating bones contains synovial fluid, which is a clear viscous fluid which lubricates the joints (as we â¦ ll as the sheaths of tendons) to reduce wear and tear. 2 people found this useful.
