What are the 4 main characteristics of synovial joints?
Synovial joints comprise most of the joints of the extremities and are the most accessible joints to direct inspection and palpation. Synovial joints share important structural components: subchondral bone, hyaline cartilage, a joint cavity, synovial lining, articular capsule, and supporting ligaments.
Where is synovial joint found?
A synovial joint is the type of joint found between bones that move against each other, such as the joints of the limbs (e.g. shoulder, hip, elbow and knee). Characteristically it has a joint cavity filled with fluid.
How are synovial joints formed?
Synovial joints allow for movement. Where the bones meet to form a synovial joint, the bones’ surfaces are covered with a thin layer of strong, smooth articular cartilage. A very thin layer of slippery, viscous joint fluid, called synovial fluid, separates and lubricates the two cartilage-covered bone surfaces.
Is the wrist a synovial joint?
The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.
What is the most common synovial joint?
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….

What is a typical synovial joint?
A typical synovial joint includes bones covered in hyaline cartilage and a joint cavity lined with a synovial membrane and filled with synovial fluid. A durable fibrous joint capsule surrounds the joint. Some synovial joints also have fibrocartilaginous discs between the bones.
What are the six types of synovial joints?
The six types of synovial joints are the pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. Pivot joints are found in your neck vertebrae, while hinge joints are located in your elbows, fingers, and knees. Saddle and plane joints are found in your hands.
What are the parts of a synovial joint?
Synovial joints are made up of five classes of tissues. These include bone, cartilage, synovium, synovial fluid, and tensile tissues composed of tendons and ligaments. Tendons are tough bands of fibrous connective tissue that connect muscles to bones.
What are the characteristics of synovial joints?
Synovial joints are characterized by the presence of a joint cavity. The walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bone’s articulating surface. The bones of the joint articulate with each other within the joint cavity.
