Description: In the appendicular skeleton, one is mostly concerned with the diarthrodial synovial joints. While this type of joint is also found in the axial skeleton (the facet (a.k.a. aphophyseal) joints and portions of the sacroiliac joints), there are also many amphiarthrodial joints which are not synovial (the intervertebral disc joints). However, there are several structures in the intervertebral disc joint which are analogous to structures found in a true synovial joint. The cartilaginous endplate, the annulus fibrosus, and the nucleus pulposus are analogous to the articular cartilage, the joint capsule and the synovial fluid of the synovial joint.
The different anatomy and physiology of these joints means that we will see different disorders affecting this part of the skeleton.
