Flashcards in Exam 1 Part 2 Deck (28):
1

What are the 3 types of joint motion?

translational, rotational, and curvilinear motion

2

Which type of joint motion is aka coupled movement and is the most common motion produced by the body?

Curvilinear motion

3

Which plane divides the body into right and left? anterior and posterior? superior and inferior?

Sagittal;
Frontal (coronal);
Transverse

4

What are the 3 axes of the 3-D coordinate system?

X, Y, and Z

5

What is the other name for the Cartesian Coordinate System?

Rectangular Coordinate System

6

T/F: Orthogonal coordinate system means its coordinate surfaces meet at right angles to one another.

True

7

T/F: The Cartesian Coordinate System is always in 3 dimensions.

False; can be 2-D as well

8

What kind of movement takes place along an axis? around the axis?

translational;
rotational

9

T/F: The potential exists for each joint to exhibit three translational movements and three rotational movements, constituting 9 degrees of freedom.

False; 6 degrees of freedom

10

Which axis is at the junction of the sagittal and transverse planes?

Z-axis

11

Which axis is perpendicular to the X-axis, running from front to back?

Z-axis

12

T/F: Positive translation along the X-axis is towards the right.

False; towards the left

13

T/F: Positive translation along the Z-axis is towards the anterior.

True

14

T/F: Negative translation along the Y-axis is toward the inferior.

True

15

T/F: Lateral glide from right to left is negative X translation.

False; right to left is positive X translation

16

T/F: Distraction is Postive Z Translation.

False; Distraction is inferior to superior, thus Positive Y translation. Positive Z Translation is P-A glide (retrolisthesis)

17

A-P glide is translation along which axis?

Negative Z translation

18

T/F: When using the "right handed system," one can point the thumb toward positive translation along any of the axes and flex the wrist. When flexing the wrist, whatever rotation the fingers point is negative rotation (negative theta) about the axis.

False; wrist flexion shows positive rotation (positive theta) about the axis

19

T/F: Flexing the neck is an example of Positive Theta X rotation.

True

20

T/F: Left Axial Rotation is postive theta Y rotation.

True

21

What type of rotation is taking place during left lateral flexion of the spine?

negative theta Z

22

Anterior translation and flexion of the spine together would be considered what?

coupled motion

23

A straight P-A adjustment would be considered what kind of movement (along what axis)?

positive Z-axis translation

24

T/F: a thrust delivered to the left TVP would make the vertebra move in negative theta Y rotation

True (slide 21)

25

T/F: Vertebral wedging is considered positive or negative theta Y rotation.

False, pos/neg theta Z rotation

26

T/F: A posterior spinous left (or right posterior body right) is described as positive theta Y.

False; negative theta Y

27

T/F: A PI listing can be described as negative Z translation and negative X translation.

False; negative Z translation and negative theta X

28

What orthogonal system descriptions can be used to describe a PRS listing?

neg theta Z translation, neg theta x, pos theta Y and neg theta Z
