synovial joints
| WKP |
Definition: A synovial joint, also known as diarthrosis , joins bones with a fibrous joint capsule that is continuous with the periosteum of the joined bones.
It constitutes the outer boundary of a synovial cavity , and surrounds the bones’ articulating surfaces.
The synovial cavity or joint is filled with synovial fluid.
The joint capsule is made up of an outer layer, the articular capsule, which keeps the bones together structurally, and an inner layer, the synovial membrane, which seals in the synovial fluid.
They are the most common and most movable type of joint in the body of a mammal. As with most other joints, synovial joints achieve movement at the point of contact of the articulating bones.
