Gliding Joint
Role of joint is
to hold bones together and allow for flexibility and movement.
Synovial fluid is found
in the joint cavity

Structure & Function
Role of a extrinsic ligament is
Reinforce the joints by keeping the bones together
Tibiofemoral joint (knee) is an example of what type of joint
Hinge

Three types of structural joints are
Synovial, Fibrous & Cartilaginous
Function of articulating Cartilage is
Protects the end of the bone & acts as a shock absorber
The radiocarpal joint (wrist) joint is an example of what type of joint
Ellipsoid joint
Carpometacarpal joint (thumb) is an example of what type of joint
Saddle joint
type of joint allows for slight movement
cartilaginous joints
A thick bands of fibrous tissue that reinforce the joint capsule is called
Intrinsic Ligaments
Proximal radioulnar joint is an example of what type of joint
Pivot joint
Characterized by an oval convex shaped bone articulating with an oval-shaped, concave cavity of another bone
Ellipsoid joint
