MULTIPLE CHOICE

1. Translation occurs when:
a. All parts of a body move in the same direction as every other part
b. All parts of a body move in opposite directions
c. A body moves around an axis of rotation
d. The center of mass is constant
ANS: A
Translation occurs when all parts of a body move in the same direction as every other part.

PTS: 1

2. If a clinician provided the force necessary to move a person’s limb through the ranges of motion, this
demonstrate:
a. Active movements c. Simulated movements
b. Gravitational range of motion d. Passive range of motion
ANS: D
Passive movement is generated by sources other than muscular activation, and movement generated i
passive range of motion.

PTS: 1

3. The motion of bones relative to the three cardinal planes of the body is known as:
a. Transverse adjustment c. Osteokinematics
b. Anatomic positioning d. Pivot point rot
ANS: C
Osteokinematics describes the motion of bones relative to the three cardinal planes of the body: sagit

PTS: 1

4. _____ describes a circular motion through two planes.
a. Adduction c. Flexion
b. Circumduction d. Extension
ANS: B
Circumduction describes a circular motion through two planes; therefore joints must have at least 2 d
to circumduct.

PTS: 1

5. When multiple points along one rotating articular surface contact multiple points on another articular
a. Roll c. Spin
b. Slide d. Lever
ANS: A
Multiple points along one rotating articular surface contacting multiple points on another articular su
across a stretch of pavement, is known as a roll.

PTS: 1

6. Rotation describes:

, 8. _____ are used in kinesiology to represent the magnitude and direction of a force.
a. Axes of rotation c. Levers
b. Vectors d. External torques
ANS: B
Vectors are used in kinesiology to represent the magnitude and direction of a force. The magnitude o
relative length of the vector line, and the direction is indicated by the orientation of the arrowhead.

PTS: 1

9. The moment arm is defined as:
a. Tension generated from ligamentous elongation
b. The arthrokinematic spin occurring in the shoulder
c. Motion occurring between the articular surfaces of joints
d. The length between the axis of rotation and the perpendicular intersection of the
force
ANS: D
This distance, called the moment arm, is the length between the axis of rotation and the perpendicula

PTS: 1

10. The amount of _____ generated across a joint depends on the amount of force exerted and the distanc
axis of rotation.
a. Torque c. Slide
b. Lever strength d. Closed-chain motion
ANS: A
The amount of torque generated across a joint depends on the amount of force exerted and the distan
axis of rotation.

PTS: 1

11. Movement of the distal segment of bone about a relatively fixed proximal segment is often referred t
a. Closed-chain motion c. Open-chain motion
b. Arthrokinematic loop d. Convex articulation
ANS: C
Movement of the distal segment of bone about a relatively fixed proximal segment is often referred t

PTS: 1

12. Movement of the proximal segment of bone about a relatively fixed—or stationary—distal segment i
a. Closed-chain motion c. Open-chain motion
b. Arthrokinematic loop d. Convex articulation
ANS: A
Movement of the proximal segment of bone about a relatively fixed—or stationary—distal segment i
closed-chain motion.

PTS: 1

13. The motion of a top moving in one spot on the floor would best be described as _____
a. Roll c. Slide
b. Spin d. Drop
ANS: B
The motion of a top moving in one spot on the floor would best be described as spin.
