Flashcards in test 2 ch 9 Deck (51):
1

function-synarthrosis

no movement

2

function- amphiarthrosis

slight movement

3

function- diarthrosis

free movement

4

joint structure

bony, fibrous, cartiligenous, synovial

5

suture

synarthrotic joint interlocked by dense fibrous connective tissue *skull

6

gomphosis

synarthrotic fibrous connection that binds teeth to sockets

7

synchondrosis

synarthrotic rigid cartiliginous bridge between 2 bones
*epiphyseal cartilage of long bones and between vertebrosternal ribs and sternum

8

synostosis

synarthrotic immovable fused bones
*epiphyseal lines

9

syndesmosis

amphiarthrotic bones connected by ligaments
*distal art. b/t tibia and fibula

10

symphysis

amphiarthrotic bones seperated by fibrocartilage
*art. b/t 2 pubic bones

11

synovial

diarthrosis- moveable joints w/n articular capsules and lined w synovial membrane

12

articular cartilage

pad art. surfaces to prevent bones touching

13

synovial fluid function

lubrication, nutrient dist., shock absorption

14

sprain

ligament with torn collagen fibers

15

bursae

pouch of synovial fluid that cushions where tendons or ligament rub

16

dislocation

luxation
*subluxation- partial dislocation

17

dynamic motion types-3

linear (glide), angular, rotation

18

3 planes of dynamic motion

monaxial, biaxial, triaxial

19

gliding

2 surfaces slide past each other
*carpal and tarsal bones

20

flexion

angular movement in anterior-posterior plane that Reduces angle

21

extension

angular movement that increases angle

22

hyperextension

past anatomical position

23

abduction

moves away from long axis

24

adduction

moves toward long axis

25

circumduction

circular motion w/out rotation

26

pronation

rotates forearm- radius over ulna

27

supination

forearm in anatomical position

28

inversion

sole of foot medially

29

eversion

twist sole of foot laterally

30

dorsiflexion

lift toes

31

plantar flexion

point toe

32

opposition

thumb grasp

33

reposition

ungrasp thumb

34

protraction

push forward

35

retration

pull back

36

lateral flexion

head side to side

37

gliding joint

monaxial, *vertebrocostal

38

hinge joint

monaxial *elbow, knee

39

pivot joint

monaxial, rotation only *radio-ulnar joint

40

condylar (ellipsoid) joint

biaxial *radiocarpal

41

saddle joint

biaxial *metacarpals

42

ball and socket

triaxial *shoulder and hip

43

intervertebral discs

anulus fibrosus- outer layer
nucleus pulposus- gelatinour core that absorbs shocks

44

slipped disc

buldge in annulus fibrosus that invades vertebral canal

45

herniated disc

nucleus pulposus breaks through annulus fibrosus and presses on spinal cord or nerves

46

1. anterior longitudinal ligament- vertebrae
2. posterior longitudinal ligament
3. ligamentum flavum

1. connects anterior bodies
2. connects posterior codies
3. connects laminae

47

4. interspinous ligament
5. supraspinous ligament
6. ligament nuchae

4. connects spinous processes
5. connects tips of spinous processes C7-sacrum
6. connects tips of spinous processes C7-skull

48

glenohumeral joint

shoulder joint

49

rheumatism

pain and stiffness of skeletal and muscular systems

50

arthritis

all forms of rheumatism that damage articular cartilages of synovial joints

51

osteoarthritis

caused by wear and tear
