Skeletal system Articulations (Joints) of Bone Diarthrosis Types of Diarthrosis Hinge Joint - the convex surface of one bone fits into the concave surface of the other. Movement is in a single plane as that of a hinged door. Movement is usually flexion and extension Hyperextension - a continuation of extension beyond the anatomical position Articulations (Joints) of Bone Diarthrosis Types of Diarthrosis Pivot Joint - a rounded or pointed surface of one bone articulates within a ring formed partly by bone and partly by ligament. Movement is primarily rotation, movement of a bone around its axis. Ex: the rotation of the atlas around the axis when we turn our head from side to side. At the wrist with the proximal ulna and radius that allows us to pronate and supinate our hands. Articulations (Joints) of Bone Diarthrosis Types of Diarthrosis

Unformatted text preview: Condyloid Joint- oval shaped articulating surface of one bone fits into a depression of another bone. Movement is side-to-side and back-and-forth. Ex.: flex/extension and adduct/abduct of the wrist Can combine above movements to form circumduction. Articulations (Joints) of Bone Diarthrosis Types of Diarthrosis Saddle Joint the articular surface of one bone is saddle-shaped and the articular surface of the other is shaped like the legs of a rider sitting in a saddle. Movement is side-to-side and back-and-forth and circumduction Articulations (Joints) of Bone Diarthrosis Types of Diarthrosis Ball and Socket- a ball-like surface of one bone fitted into a cuplike depression of another bone. Permits movement in there planes flexion-extension abduction- adduction rotation-circumduction...
