Flashcards in Chapter 7; Bio 210 (Joints and Kinesiology) Deck (40):
1

Articulate

to join

2

Skeletal Articulation

-two or more bones
-bone and teeth
-bone and cartilage

3

Arthrology

study of articulations (also known as joints)

4

Kinesiology

study of body movement (occurs at joints)

5

Greater Movement =

less strength

6

Synarthrotic Joint

immovable joint (sutures of skull)

7

Amphiarthrotic Joint

slight movable (pubic symphesis and ribs)

8

Diarthrotic Joint

freely movable (synovial joints)

9

3 Functional Classifications of joints

synarthrotic (fibrous joint)
amphiarthrotic (cartilaginous joint)
diarthrotic (synovial joint)

10

3 Structural Classifications

-classified by how it moves, not what it's made of
fibrous joint (little or no movement)
cartilaginous joint (slightly movable)
synovial joint (freely movable)

11

Bursa

comfort of the ligament

12

PG 181 textbook KNOW IT!

-

13

Muscle Tone

partial state of contraction of a muscle

14

Luxation

complete dislocation of a joint

15

Subluxion

partial dislocation of a joint

16

Sprain

muscle is stretched but ligament can't stretch too well

17

Abduction

away from longitudinal axis of body in frontal plane (appendenges) jumping jacks out

18

Adduction

towards the longitudinal axis of body (appendenges) jumping jacks in

19

Inversion

foot in

20

Eversion

foot out

21

Plantar Flexion

foot down (high heels)

22

Dorsal Flexion

foot up

23

Protraction

mandible pushed out

24

Retraction

mandible pushed in

25

Supernation

UP plams (anatomical position

26

Pronation

just wrists move up

27

(Synovial)
Plane Joint (gliding)

Vertebrae, Acromioclavicular, Metatarsals

28

(Synovial)
Pivot Joint

Proximal and Distal radioulnar

29

(Synovial)
Hinge

Cubital (elbow) Patella

30

(Synovial)
Ball and Socket

Humeral, Coaxal

31

(Synovial)
Elipsoid

Atlantooccipital (head connects to spine within foramen magnum)

32

(Synovial)
Saddle

Pollex (Thumb) and fingers

33

Three possible types of movement by joints

Gliding
Angular
Circular

34

Gliding movement

two surfaces slide past each other
-diarthrotic but not a large range of movement
- Ex: Tarsal bones, carpal bones, sternum/clavicle

35

Angular motion

Flexion- bend forward and backwards
Extension/Hyperextension- standing on leg
Abduction- jumping jack arm out
Adduction- jumping jack arm in
Circumduction- Jesus with 4 arms

36

Shoulder Joint

gelnohumeral joint (more motion than ANY joint)

37

Elbow Joint

humeroulnar joint (smaller is humeroradial joint)

38

Hip joint

coaxal joint

39

Rheumatism

pain of joints and muscles

40

Arthritis

rheumatism affecting synovial joints
