Terms in this set (25)

7 types of Angular Motion
1) Flexion
2) Extension
3) Hyperextension
4) Lateral Flexion
5) Abduction
6) Adduction
7) Circumduction
Flexion
The ANGLE between articulating bones DECREASES
Extension
The ANGLE between articulating bones INCREASES
Hyperextension
Extension movement continues PAST THE ANATOMIC POSITION
Lateral Flexion
the vertebral column moves/bends in a LATERAL DIRECTION along a CORONAL PLANE
Abduction
movement of the bone AWAY FROM THE MIDLINE
Adduction
movement of the bone TOWARD THE MIDLINE
Circumduction
the DISTAL END of the limb or digit MOVES IN A CIRCLE
2 Types of Rotational Motion
1) Pronation
2) Supination
Pronation
ROTATION of the forearm where the PALM IS TURNED POSTERIORLY
Supination
ROTATION of the forearm where the PALM IS TURNED ANTERIORLY
9 Types of Special Movements

Depression
Movement of the BODY PART INFERIORLY
Elevation

Plantar Flexion
Movement of the FOOT POSTERIORLY
Inversion
TWISTING motion of the foot turns the
SOLE MEDIALLY / INWARD
Eversion
TWISTING motion of the foot turns the
SOLE LATERALLY / OUTWARD
Protraction
ANTERIOR MOVEMENT of a body part from anatomic position
Retraction
POSTERIOR MOVEMENT of a body part from anatomic position
Opposition
Movement of the THUMB ACROSS THE PALM TOWARD THE FINGERS to permit grasping and holding of an object
Gliding Motion
Two opposing articular surfaces slide past each other in almost any direction, the amount of movement is slight
Angular Motion
The angle between articulating bones increases or decreases
Rotational Motion
A bone pivots around it's own longitudinal axis
