Definition
1. Sagittal: anterior to posterior plane
2. Frontal: Side to side plane
3. Transverse: Separates inferior and superior |
|
|
Term
| The axes to the sagittal, frontal, and transverse plane |
|
Definition
Sagittal: frontal axis (aka bilateral)
Frontal: Sagittal (aka Anteroposterior) axis
Transverse: Vertical axis |
|
|
Term
| Name the 2 kinds of motion |
|
Definition
1. Translatory or linear (object is translated as a whole from one location to another
2. Rotary or angular (object acting as a radius moves about a fixed point) |
|
|
Term
| Name the two types of translatory motion, and give examples |
|
Definition
1. Rectlinear (straight line progression) ie sledding down hill
2. Curvilinear (curved translatory movement) ie. diving board |
|
|
Term
| What is a special type of curvilinear motion? Give an example |
|
Definition
Circular Motion: doesn't appear to be translatory...object moves along a curved path of a constant radius...but if force stops acting on it, it will move in a linear path.
Ie. Softball pitch |
|
|
Term
What's the difference between circular and angular motion?
|
|
Definition
Circular describes motion of any point on the radius.
Angular motion is descriptive of motion of the entire radius.
ie. ball is moving with circular motion, arm acts as a radius moving with angular motion |

|
Term
|
Definition
| combo of rotary and translatory motion. Ie..a fencer. Angular of forearm and upper arm, or legs. Hand travels linearly. |
|
|
Term
| Most movements within the body are angular, while outside tend to be linear. What is an exception? |
