PART 4

Question 1

passes horizontally from posterior to anterior and is formed by the intersection of the sagital and transverse planes.

Answer 1

The sagital axis

Question 2

passes horizontally from left to right and is formed by the intersection of the frontal and transverse planes.

Answer 2

The frontal axis

Question 3

passes vertically from inferior to superior and is formed by the intersection of the sagital and frontal planes.

Answer 3

The vertical axis

Question 4

often referred to in the particular plane it is dominated by, such as describing walking as a sagital plane movement.

Answer 4

Movement

Question 5

What occurs at the individual joint level during movement?

Answer 5

At the individual joint level, movement occurs in several planes, not solely in the sagital plane.

Question 6

the simultaneous movement seen as one motion with three components.

Answer 6

tri-planar motion

Question 7

Why is understanding tri-planar motion important for exercise professionals?

Answer 7

It is essential for exercise professionals to be comfortable with tri-planar motion concepts as all functional movements are three-dimensional.

Question 8

What is the benefit of describing movements in single plane terms?

Answer 8

Describing movements in single plane terms is most useful when generalizing about gross movement patterns.
