movments of joints (DEFINITIONS)

— so like no photos...

Gliding motion

two opposing articular surfaces slide past each other in almost any direction; the amount of movement is slight

angular motion (definition)

The angle between articulating bones increases or decreases

Flexion

— angular motion
The angle between articulating bones decreases in an anterior-posterior (AP) plane
(opposing movement : extension)

Extension

— angular motion
The angle between articulating bones increases in an anterior-posterior (AP) plane
(opposing movement : flexion)

Hyperextension

— angular motion

Extension movement continues past 180 degrees
( opposing movement : flexion )

Lateral flexion

— angular motion
The vertebral column moves (bends) in a lateral direction along a coronal plane
( opposing movement : none )

Abduction

— angular movement
lateral movement of a body part away from the midline
( opposing movement : adduction )

Adduction

— angular motion
lateral movement of a body part toward the midline
( opposing movement : abduction )

Circumduction

— angular motion
a continuous movement that combines flexion, abduction, extension and adduction in succession; the distal end of the limb or digit moves in a circle
( opposing movement : none )

Rotational motion (definition)

A bone pivots around its own longitudinal axis

Pronation

— rotational motion
rotation of the forearm where the palm is turned posteriorly or inferiorly
( opposing movement : supination )

Supination

– rotational motion
rotation of the forearm in which the palm is turned anteriorly or superiorly
( opposing movement : pronation )

Special movements ( definition )

types of movement that do not fit into the previous categories

Depression

— special movement
Movement of a body part inferiorly
( opposing movement : elevation )

Elevation

— special movement
Movement of a body part superiorly
( opposing movement : depression )

Dorsiflexion

— special movement
Ankle joint movement where the dorsum (superior surface) of the foot is brought toward the anterior surface of the leg
( opposing movement : plantar flexion )

Plantar flexion

— special movement
Ankle joint movement where the sole of the foot is brought toward the posterior surface of the leg
( opposing movement : dorsiflexion )

Eversion

— special movement
Twisting motion of the foot that turns the sole laterally or outward
( opposing movement : inversion )

Inversion

— special movement
Twisting motion of the foot that turns the sole medially or inward
( opposing movement : eversion )

Protraction

— special movement
Anterior movement of a body part from anatomic position
( opposing movement : retraction )

Retraction

— special movement
Posterior movement of a body part from anatomic position
( opposing movement ; protraction )

Opposition

— special movement
Special movement of the thumb across the palm toward the fingers to permit grasping and holding of an object
( opposing movement : reposition )
