Flashcards in Ch 8 Lec 1 - Articulations Deck (59):
1

these hold bones together but may permit movement

joints

2

study of joints

arthrology

3

study of motion

kinesiology

4

three classifications of joints

synarthrosis, amphiarthrosis, diarthrosis

5

classification of joints based on anatomy

fibrous, cartilaginous, synovial

6

collagen fiber joints

fibrous

7

cartilage joints

cartilaginous

8

joint capsule, ligaments, and fluid in this joint

synovial

9

fibrous joints lack a blank cavity

synovial

10

little or no movement joints

fibrous joints

11

three types of fibrous joints

sutures, syndesmoses, gomphoses

12

thin layer of dense fibrous connective tissue unites bones of the skull and are immovable

sutures

13

if sutures are fused completely then it is called blank

synostosis

14

blank bones fuse together to become one in humans

frontal

15

fibrous joint where bones are united by a ligament and slightly movable

syndesmosis

16

anterior tibiofibular joint and interosseous membrane are these kinds of joints

syndesmosis

17

ligament holds cone shaped peg in a bony socket and is immovable joint

gomphosis

18

teeth in alveolar processes of maxillae or mandible are an example of this joint

gomphosis

19

these joints lack a synovial cavity and allows little or no movement but bones are tightly connected by fibrocartilage or hyaline cartilage

cartilage joints

20

two types of cartilage joints

symphysis, synchondrosis

21

connecting material is hyaline cartilage and is immovable in this joint

synchondrosis

22

epiphyseal plate or joints between the ribs and sternum are these kinds of joints

synchondrosis

23

when fusion of synchondroses it is called

synostosis

24

fibrocartilage is the connecting material and these joints are slightly movable

symphysis

25

intervertebral discs and pubic symphysis are this joint

symphysis

26

men and women pelvic differences and bone model

l

27

2 bones separated by a fluid filled cavity in this joint

synovial

28

this is made of blood filtrate, hyaluronic acid, and glycoproteins

synovial fluid

29

function of synovial fluid

lubricate joint surface, shock absorber, nourish chondrocytes

30

reinforce and strengthen joint capsule and connect bone to bone

ligament

31

ligaments are made of this connective tissue

dense regular

32

ligaments outside the joint capsule, collaterals

extracapsular

33

ligaments within capsule, cruciates

intracapsular

34

pads of fibrous cartilage that subdivide a cavity and are also known as menisci

articular discs

35

knee joint and ulnolunate joint are blank

articular discs

36

three functions of articular discs

channel flow of synovial fluid, modifies articular surface, restrict movements at joint, help distribute body weight, cushion articulating surfaces

37

adipose tissue surrounding the synovial capsule

fat pads

38

small fluid filled pockets of connective tissue between tendons/ligaments and bones

bursae

39

two opposing surfaces slide past one another in this joint

gliding

40

example of gliding joint

sternoclavicular joint

41

movement with a change in angle between the shaft and the articular surface

angular movement

42

type of angular motion with rotation of the shaft while changing the angle

circumduction

43

spinning of the shaft without changing the angle

rotation

44

ball and socket joint has this movement

circumduction

45

twisting head is blank motion of the head

rotation

46

types of angular movement

abduction, adduction, flexion, extension, hyperextension

47

two types of rotation

pronation, supination

48

synovial joints are a trade off between blank and blank

flexibility, stability

49

six types of synovial joints

plane, hinge, pivot, condylar, saddle, ball and socket

50

synovial joint where bone surfaces are flat or slightly curved and side to side movement only

plane

51

intercarpal, intertarsal, sternoclavicular, and vertebrocostal are blank joints

plane

52

convex surface of one bones fits into concave surface of 2nd bone and is monoaxial

hinge

53

knee, elbow, ankle, and interphalangeal joints are these

hinge

54

rounded surface of bone articulates with ring formed by 2nd bone and ligament and is monoaxial that only allows for rotation and longitudinal axis joint

pivot

55

proximal radioulnar joint is this type of joint

pivot

56

oval shaped projection fits into oval depression and is biaxial

condylar

57

wrist is blank joint

wrist

58

one bone fits over another bone like a horse and is biaxial

saddle joint

59

trapezium of carpus and metacarpal of the thumb are this joint

saddle
