The cervical(neck) vertebrae. The joint formed by C1 and C2, also known as the atlas and axis.
There is only one pivot joint in the body and it is located in the neck. It is the joint between the first and second cervical vertebrae also known as atlas and axis respectively. Axis has a the "peg" part of the pivot projecting upwards and atlas has the hole around it. This is the joint that allows the heart to rotate left to right.There are two pivot joints. One between C1 and C2 of the vertebrae. The second in the forearm between the ulna and radius.
What is degenerative joint disorder in the vertebrae? and what can it do to a human?
what type of joint is between bodies of vertebrae ? cartilaginous joint
The odontoid of the second cervical vertebrae (ie: the axis) forms a joint with the anterior ring of the first cervical vertebrae (ie: the atlas). This joint is primarily responsible for allowing the head to rotate from side to side as if you were nodding "no" to someone. See the related link for further information.
The first and second cervical vertebrae form the atlantoaxial joint. These bones are known as the atlas and the axis.
A Ball and Socket Joint
A condyloid joint!
A ball and socket joint allows twisting and turning side to side. It humans this would be the hip joint

This is called a gliding joint.ball and socket
Ball and socket joint as found in the hip and shoulder.
This joint allows for slight movement. A good example are most of the spinal vertebrae. A person with more movement would be rather unstable.
What is degenerative joint disorder in the vertebrae? and what can it do to a human?
The joint between the skull (occipital bone) and first vertebrae (atlas) is a condyloid joint (the condyles are on the occipital bone). This joint allows your head to lean forward and backward. The joint between the first vertebrae and second vertebrae (axis) is a pivot joint, which allows you to turn your head to look left or look right. (The pivot is the dens of the axis.) The other intervertebral joints I do not think fall into a clear classification, although whatever text you are using might try to put them into one category or the other for illustrative purposes. The whole column is basically held together by many ligaments, with discs between each vertebrae, which allows for a wide range of motion. The sacral and coccygeal joints, however, are fused.
A Planar joint is also known as a gliding joint, and allows sliding or back and forth motions as well as twisting movements.Examples of Planar joints are in the wrists and ankles, and the joints between the vertebrae in the spine.
The four kinds of movable joints are hinge joint, ball-and-socket, pivot joint, and gliding joint.Movable joint: allows forward or backward.Ball-and-socket joint: allows the greatest range of motion.Pivot joint: allows one bone to rotate around another.Gliding joint: allows one bone to slide over another.~ A.
