Term Definition
Non-Genuine Joints (Synarthroses) Are in a continuous bone connection in contrast to the discontinuous bone connections. Examples: skull, pelvis
Synovial Joints Designated as freely moving joints; allow a wide range of movement
Free Joints (Three- or Four-Axis Joints) Joints that have the greatest latitude. Example: Ball-and-Socket
Two-Axis Joints Far greater degrees of movement than single-axis joints; articulated bones can move freely in two axes vertical to one another; 2 degrees of freedom; movements of axes complement each other; Examples: ellipsoid, saddle, & plane joints
Single-Axis Joints Are built so that the articulated bones can move freely in one plane; have one degree of freedom. Examples: hinged & pivot joints
Ball-and-Socket Joint Joint with the greatest possibilites for movement; has three main axes vertical to one another. Examples: shoulders & hips
Ellipsoidal Joint Among the two-axis joints with 2 degrees of freedom; allows movement around two axes vertical to each other. Examples: Wrists & Ankles
Saddle Joint Has 2 degrees of freedom and 2 main axes; consists of 2 saddle-shaped joint mice, each of which has a convex curve in one axis and a concave curve in the other axis. Example: Thumb
Plane Joint Describes a joint form with two plane joint surfaces; has 2 degrees of freedom; allows planes to slide past each other according to the time of the shifting joint. Example: Vertebrae
Hinged Joint One-axis joint; is the simplest form of the jointed connection between two bones; only allows movement in one axis. Example: Finger, upper arm-elbow
Pivot Joint One axis and one degree of freedom. Example: lower radius-elbow
