Question 3

Osteokinenamatic motion

Answer 3

movement of bones

Question 4

Arthrokinematics motion

Answer 4

movements of joint surface (roll, spins

Question 5

AROM

Answer 5

muscles contract to move joints

Question 6

PROM

Answer 6

when therarpist or machine moves joint

Question 7

joint play

Answer 7

arthro movement happens b/t join surfaces during external force

Question 8

traction forces(distraction)

Answer 8

pull joints apart, pull ups

Question 9

approximation

Answer 9

pushing joints together, push ups

Question 10

shearing force

Answer 10

cause a gliding motion

Question 11

Ovoid

Answer 11

bones forming convex/concave, same direction

Question 12

Sellar

Answer 12

convex/concave in opposite direction

Question 13

Roll

Answer 13

rolling of one joint surface on another

Question 14

Glide

Answer 14

linear movement of one joint surface to other

Question 15

Spin

Answer 15

rotation of movable joint, same point remain in contact

Question 16

Concave

Answer 16

joint surfaces glide in the same direction as motion of distal bone

Question 17

Convex-

Answer 17

join surface glide in opposite direction compare to distal end

Question 18

Open-packed position

Answer 18

least amount of joint surface contact, ligs are lax,(roll,glide

Question 19

Closed-packed position

Answer 19

max contact with ligaments, tightly compress, knee extended
