Supination
Movement of the form so the palm is turned
Pronation
Movement of the forearm so that the palm is turned backwards
Plantar flexion
Bending of the foot towards the plantar surface (stand on your toes)
Dorsiflexion
Bending of the foot in the direction of the dorsum (stand on your heels)
Eversion
The movement of the soles laterally so that they face away from each other
Protraction
The movement of a body part forward
Elevation
The upward movement of a body part
Circumduction
The movement of the distal end of a part of the body in a circle
Adduction
Movement of the bone toward the midline
Flexion
Decrease in the angle between the articulating bones
Gliding movement
Movement back-and-forth and side to side
Ball and socket joint
Permit flexion, extension, abduction, adduction, circumduction, and rotation
Hip and shoulder joints
Saddle joints
Permits flexion, extension, abduction, adduction and circumduction
Joint in the thumb
Condyloid joint
Permits flexion, extension, abduction, adduction and circumduction
Wrists and metacarpophalangeal joints
Pivot joints
Atlantoaxial joint
Allows you to shake your head no
Synovial joint
Diathroses
They are freely movable
They contain a joint capsule, synovial membrane, joint cavity, articular cartilage, and ligaments
Have a synovial cavity
Cartilaginous joints
Amphiarthroses
Cartilage joins bones together, they are slightly movable.
Example the pubis symphysis
Three types of joints
Fibrous
Cartilaginous
Synovial
Inversion
The movement of the soles medially so they face each other
Retraction
The movement of a protracted part back
Depression
The downward movement of a body part
Rotation
A bone resolves around its own longitudinal axis
Abduction
Movement of bones away from the midline
Hyperextension
Continuing the extension beyond the anatomical position
