Translatory motion's alternate name?
Linear Displacement
Definition of Translatory Motion is...
movement of a segment in a straight line when force is applied to the center of the object.
Give an alternate name for Rotary Motion
Angular displacement
Define the term rotary motion..
Movement of segment around a fixed axis in a curved path.
Perfect rotary motion does not really occur in joints because.....
Translation is difficult to prevent
The term Rotatory Motion is used to describe motion. (T/F)
True
Translatory Motion is a common movement in the body. (T/F)
False
Curvilinear motion is the combination of _____________ and ____________ of a segment.
translation and rotation
The ___________ axis runs "front to back
Sagittal
The ___________ axis runs "up and down
Longitudinal
The ___________ axis runs "side to side
Frontal
The cardinal sagittal plane cuts the body in _________ ___ ___________ parts.
Right and Left
Rotation of a segment around the vertical axis occurs in the _________ ___________
sagittal plane
Rotation of a segment around the frontal axis occurs in the _________ ___________
transverse plane
Rotation of a segment around the saggital axis occurs in the _________ ___________
frontal plane
When describing movement based on Axis and Planes, the plane and axis are ____________________ to each other when visualizing the concept.
perpendicular
When discussing motion, you must always specify which JOINT is being moved, not the segment. (T/F)
True
State which plane moves around which axis when discussing Flexion/Extension
Sagittal plane around frontal axis
