Roll, Spine, Glide

Question 1

gross movements of bones at joints

Answer 1

osteokinematics

Question 2

examples of osteokinematics

Answer 2

flexion/extension
abduction/adduction
internal rotation/external rotation

Question 3

small amplitude motions of bones at joint surface

Answer 3

arthrokinematics

Question 4

examples of arthrokinematics

Answer 4

roll
glide (or slide)
spine

Question 5

oteokinematics are typically the terms we use to decribe

Answer 5

motion

Question 6

osteokinematic movements happen at

Answer 6

synovial joints

Question 7

osteokinematics occur around

Answer 7

center of rotation (joint axis)

Question 8

general term for specific movements of joint surfaces

Answer 8

arthrokinematics

Question 9

arthokinematics (normal joint surface movement) is necessary to ensure

Answer 9

long-term joint integrity

Question 10

arthrokinematics is referred to as

Answer 10

joint play motions or component motions

Question 11

joint surfaces move with respect to one another by simultaneously

Answer 11

rolling
gliding
sliding
spinning

Question 12

these typically occur simultaneously

Answer 12

rolle
glide
spin

Question 13

this is typically ignored

Answer 13

spine

Question 14

convex-concave rule

Answer 14

each joint or articulation involves two bony surfaces, one that is convex and one that is concave

Question 15

when the concave surface is fixed and the convex surface moves on it

Answer 15

the convex surface rolls and glides in opposite directions

Question 16

when the convex surface is fixed and the concave surface moves on it,

Answer 16

the concave surface rolls and glides in the same direction

Question 17

if the moving joint surface rolls on its partner without simultaneously gliding

Answer 17

the surfaces would separate (gap or subluxate) in some places and impinge in others

Question 18

these must occur simultaneously to preserve joint integrity

Answer 18

roll and glide

Question 19

we can predict and understand the relationship between bony shapes at a joint surface and the surfaces movements by

Answer 19

applying the rules of convexity and concavity

Question 20

roll and glide to not occur in the direction they do because

Answer 20

of the shape of the joint surfaces

Question 21

roll and glide, like all motions,

Answer 21

are produced by forces

Question 22

describe the humerus

Answer 22

proximal end is convex, distal end is convex (capitulum and trochlea)

Question 23

describe the ulna

Answer 23

proximal end is concave (proximal radioulnar joint and humeroulnar joint), distal end is convex (distal radioulnar joint)

Question 24

describe the radius

Answer 24

proximal end is concave (radioulnar joint) and convex (proximal radioulnar joint), distal end is concave (distal radioulnar joint)

Question 25

what happens with the radius during pronation

Answer 25

radius anterior roll and posterior glide over ulna (proximal radioulna)
-radius anterior roll and anterior glide over ulna (dorsal radioman joint)

Question 26

radius and ulna are ____ and carpal bones are ____ (radoiocarpal and ulnarcarpal joint)

Answer 26

concave

convex

Question 27

describe wrist extension

Answer 27

posterior roll and anterior glide of carpals

-posterior roll and posterior glide of radius and ulna

Question 28

shoulder abduction is

Answer 28

superior roll and inferior glide

Question 29

shoulder flexion is

Answer 29

posterior roll and anterior glide

Question 30

shoulder extension is

Answer 30

anterior roll and posterior glide

Question 31

shoulder glides and roll are dependent on

Answer 31

size of humerus head
tightness of joint capsule and muscular forces
-smaller head rolls more, larger head glides more
