Gliding or plane joints are points where bones meet as flat surfaces and can freely glide past each other in any direction. Although it sounds similar to a ball and socket joint, condyloid joints only allow for forward-backward and side to side movement and do not allow rotation. Umbra & Penumbra Lesson for Kids: Definition & Facts. While they seem simple, joints are complicated body parts with abilities that vary based on their structure.

Additionally, bones at synovial joints may be supported by structures outside of the joint such as ligaments, tendons, and bursae (fluid-filled sacs that reduce friction between supporting structures at joints). An example of immovable joints are the plates of the skull. A pivot joint is what enables the neck to rotate to the left and right and the forearm to make a rotating motion. Joints are classified as either fibrous or cartilaginous, with one type of each considered slightly movable. A good example of a slightly moveable joint would be the vertebrae of the spine.

Like the other joints in the body, plane joints can be affected by arthritis. Movement in all directions is allowed. Joints fall into two basic categories: fibrous and cartilaginous joints, which contain connecting tissue and are mostly fixed in place, and synovial joints, which contain synovial fluid that enables movement as one bone smoothly slides over another. Also known as rotary joints or trochoid joints, pivot joints are composed of one bone that swivels within the ring of a second bone allowing for rotation. Leonello Calvetti/Stocktrek Images/Getty Images. The reason why this is not an exact number is because the number of joints can vary with age, the number ofsesamoidscan vary, and the definition of joints can either be the point at which two bones connect or the point where bones connect for the purpose of movement. Some examples of hinge joints include fingers, toes, ankles, elbows, and knees. These complicated connectors make it possible to move from place to place and to eat, work and play.
