~Bending 
~Torsion

Question 9

Kinetics

Answer 9

The stuidy of forces associated with motion

Question 10

Kinematics

Answer 10

Study of the description of motion, “appearance”

Question 11

Kinesiology

Answer 11

Study of human movement

Question 12

Sagittal plane

-movements-

Answer 12

Divides body into left and right

-Flexion/ extension-

Question 13

Frontal/Coronal plane

-movements-

Answer 13

Divides body into front and back

• Adduction/abduction-
• Ulnar and radial deviation-
• Inversion/Eversion-
• Lateral flexion-

Question 14

Transverse/Horizontal plane

-movements-

Answer 14

Divides body into top and bottom

• rotations-
• Wrist pronation/supination-
• Horizontal abduction/adduction-

Question 15

How many bones in the body?

Answer 15

206

177 are involved in movement

Question 16

Short bone function?

Answer 16

Shock absorption

Question 17

Concentric Contraction

Answer 17

• muscle force is sufficient to overcome a resistance and move the body segment, shortening of the muscle
• muscle force is greater than external force

Question 18

Eccentric Contraction

Answer 18

• when a muscle lengthens as it gives in to an external force that is greater than the contractile force it is exerting
• muscle controls movement, muscle is pulling but another force is causing the movement
• gravity lowering arms but slowly lowering arms

Question 19

Isometric/ static Contraction

Answer 19

• muscle force is equal to external force, thus no movement

- occurs when antagonist muscles contract with equal strength and when a muscle is held against another force

Question 20

Isotonic Contraction

Answer 20

• equal tension (one tone), tension remains constant while muscle shortens or lengthens
• can be concentric or eccentric

Question 21

Isokinetic Contraction

Answer 21

• equal speed, max muscle effort at the same speed

- can be concentric or eccentric

Question 22

Agonist

Answer 22

• movers, directly responsible producing a movement, performs concentric movements
• prime movers (large impact on movement, the boss) assistant movers (only help when needed)

Question 23

Antagonist

Answer 23

• role played by a muscle acting to slow or stop a movement

- most active to slow a movement (at the end of the movement)

Question 24

Woles law ?

Answer 24

Bone strength increase and decreases as the function forces on the bones increase and decrease

Question 25

Vectors have?

Answer 25

magnitude and direction

force and velocity

Question 26

Function for

• long bones
• short bones
• flat bones

Answer 26

• movement
• shock absorption
• protection/muscle
• insertion

Question 27

What measure acceleration/movement of joints?

Answer 27

Pacinian Corpuscles

Question 28

Components of Active tissue

Answer 28

muscle fibers

“contractility and excitability”

Question 29

Components of Passive tissue

Answer 29

tendons

“extensibility and elasticity”

Question 30

Influence of gravity

Answer 30

picking up a book:
lifting book: concentric contraction of agonist
Lowering the book: eccentric contraction of same muscle

Question 31

Carpal Tunnel

Answer 31

Median nerve is swollen

Question 32

Shoulder movement muscles

• Downward rotation-
• elevates-
• protraction-

Answer 32

• rhomboid major/minor, levator scapula-
• levator scapula-
• Serratus anterior , pec minor-

Question 33

Long bone function?

Answer 33

Levers arms for movement

Question 34

Flat bone function?

Answer 34

Protection of internal organs and site for muscle attachment
