Extension
A straightening movement in which the relative angle between two adjacent segments increases
External Feedback
Info provided by some external source, such as a health and fitness professional, videotape, mirror, or heart rate monitor, to supplement the internal environment
Rotation of a joint away from the middle of the body
External Rotation
Abduction
A movement in the frontal plane away from the midline of the body
Scapular Elevation
Upward (superior) motion of the scapula
Positioned on the same side of the body
Ipsilateral
Rotarty Motion
Movement of the boes around the joints
Sagittal Plane
An imaginary bisector that divieds the body into left and right halves
When a muscle shortens at a constant speed over the full range of motion
Isokinetic Muscle Action
How the CNS integrates internal and external sensory info with previous experiences o produce a motor response
Motor Control
Scapular Depression
Downward (inferior) motion of scapula
Muscle Synergies
Groups of muscles that are recruites by the CNS to provide movement
Scapular Protraction
Abduction of scapula; shoulder blades move away from midline
Motor Behavior
Motor response to internal and external environmental stimuli
Hyperextension
Extension of a joint beyond the normal limit or range of motion
Horizontal Adduction
Movement of the arm or thigh in the transverse plane from a lateral position to an anterior position
Motor response to internal and external environmental stimuli
Motor Behavior
Isokinetic Muscle Action
When a muscle shortens at a constant speed over the full range of motion
Muscle groups moving together to produce movement around a joint
Force-Couple
Info provided by some external source, such as a health and fitness professional, videotape, mirror, or heart rate monitor, to supplement the internal environment
External Feedback
Distal
Positioned farthest from the center of the body, or point of reference
The cumulative sensory input to the CNS from all mechanoreceptors that sense position and limb movements
Proprioception
Flexion
A bending movement in which the relative angle between two adjacent segments decreases
Anterior (or Ventral)
On the front of the body
