Example of a gliding joint?
Articular processes between vertebrae
Decreases the angle between bones and bends or folds one part on another?
Flexion
Increases the angle between bones and returns a part from its flexed position to its anatomical position
Extension
Stretching or extending a part beyond its anatomical position
Hyperextension
Increases the angle between the top of the foot and the front leg.
Plantar flexion
Decreases the angle between the top of the foot and the front leg
Dorsiflexion
Moves away from the median plane
Abduction
Moves a part toward the median plane
Adduction
Immovable joints
Synarthroses
Radioulnar articulation
Syndesmosis
Most movable joint
Synovial joints
Example of a symphysis
The articulation between the pubic bones
The articulation between the bodies of adjacent vertebrae
The inner surface of the joint capsule is lined with what?
Synovial membrane
The joint that allows for the widest range of movement
Ball-and-socket
Joint between bodies of vertebrae
Amphiarthroses
