Explanation:

The syndesmosis can be defined as a fibrous joint held together by ligaments. Sutures are fibrous joints of tissue that link the cranial bones of the skull. A gomphosis is a mobile fibrous that binds the teeth into sockets in the mandible and maxilla. Synovial joints are joints found between bones that move against each other (e.g., shoulder bones). They (synovial joints) are the most common class of joints found in the body. A symphysis is a cartilaginous, slightly movable, joint between two bones. A saddle is a synovial joint whose opposing surfaces are concave and convex, respectively. Osteoarthritis is the most common type of arthritis, this condition occurs when the protective cartilage surrounding the bones wears away over time. Finally, eversion refers to a type of movement of the foot which occurs in the auctioneering joint.
