Exam 1 Part 2

Question 1

What are the 3 types of joint motion?

Answer 1

translational, rotational, and curvilinear motion

Question 2

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

Answer 2

Curvilinear motion

Question 3

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

Answer 3

Sagittal;
Frontal (coronal);
Transverse

Question 4

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

Answer 4

X, Y, and Z

Question 5

What is the other name for the Cartesian Coordinate System?

Answer 5

Rectangular Coordinate System

Question 6

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

Answer 6

True

Question 7

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

Answer 7

False; can be 2-D as well

Question 8

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

Answer 8

translational;

rotational

Question 9

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

Answer 9

False; 6 degrees of freedom

Question 10

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

Answer 10

Z-axis

Question 11

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

Answer 11

Z-axis

Question 12

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

Answer 12

False; towards the left

Question 13

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

Answer 13

True

Question 14

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

Answer 14

True

Question 15

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

Answer 15

False; right to left is positive X translation

Question 16

T/F: Distraction is Postive Z Translation.

Answer 16

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

Question 17

A-P glide is translation along which axis?

Answer 17

Negative Z translation

Question 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.

Answer 18

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

Question 19

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

Answer 19

True

Question 20

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

Answer 20

True

Question 21

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

Answer 21

negative theta Z

Question 22

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

Answer 22

coupled motion

Question 23

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

Answer 23

positive Z-axis translation

Question 24

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

Answer 24

True (slide 21)

Question 25

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

Answer 25

False, pos/neg theta Z rotation

Question 26

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

Answer 26

False; negative theta Y

Question 27

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

Answer 27

False; negative Z translation and negative theta X

Question 28

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

Answer 28

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