It is a non-axial joint as there is no rotatory motion around any axis. In general, a human body has around 300 joints altogether, which works in a specific way to complete different functions of the human body. The length of the connective fibers between bones determines the degree of movement provided by these joints. The two classification schemes correlate: synarthroses are fibrous, amphiarthroses are cartilaginous, and diarthroses are synovial. },{ In between two vertebrae, there is a gap that is filled with cartilage called the intervertebral disc. The distinguishing feature of the diarthrodial joint from the fibrous or cartilaginous joints is the presence of a joint cavity in it.
