Ch.2 Flashcards
Erect standing position with all body parts, including the palms
of the hands, facing forward; considered the starting position for
body segment movements
Anatomical Reference Point
Involving rotation around a central line or point
Angular
Imaginary line perpendicular to the plane of rotation and passing
through the center of rotation
Axis of rotation
Three imaginary perpendicular reference planes that divide the body in half by mass
Cardinal planes
Along a curved line
Curvilinear
Imaginary line passing through the body from side to side and
around which sagittal plane rotations occur
Frontal axis
Plane in which lateral movements of the body and body
segments occur
Frontal plane
Motion involving translation and rotation simultaneously
General motion
Along a line that may be straight or curved, with all parts of the
body moving in the same direction at the same speed
Linear
Imaginary line passing from top to bottom through the body and
around which transverse plane rotations occur
Longitudinal axis
Along a straight line
Rectilinear
Imaginary line passing from front to back through the body and
around which frontal plane rotations occur
Sagittal axis
Plane in which forward and backward movements of the body
and body segments occur
Sagittal plane
Object or group of objects chosen by the analyst for study
System
Linear motion
Translation
Plane in which horizontal body and body segment movements occur when body is standing erect position
Transverse plane
To effectively analyze a motor skill, the analyst needs to identify…
