Bony joints

Complete bone fusion

1

Ex of bony joint

Metopic suture

2

Fibrous joint

Held together by collagen fibers

3

Cartilaginous

Similar to hyaline, but contains water

4

Synovial

Has articulated capsule and fluid

5

Synarthrosis

Immovable joint

6

Ex of synarthrosis

Sutures
Gomphoses
Synchondroses
Synostoses

7

Sutures

Found in the skull

8

Gomphoses

Teeth articulate to jaw bones

9

Synchondroses

Epiphyseal plates, rib 1 to sternum

10

Synostoses

Metopic suture

11

Ampiarthrosis

Slightly moveable

12

Syndesmoses

Distal tib/fib

13

Sympyses

Pubic bones, between centra of vertebrae

14

Ampiarthrosis examples

Syndesmoses and symphyses

15

Diarthrosis

Highly moveable; weak joints

16

What are the 6 Diarhrosis joints

Gliding, hinge, pivot, ellipsodial, saddle, and ball and socket

17

Ex of gliding joints

Between articulate processes of vertebrae, intercarpal, intertarsal

18

Ex of hinge joint

Elbow, knee, interphalangeal

19

Pivot joint

Alanto-Axial, proximal radioulnar

20

Ellipsodial joints

Radiocarpal, metatarsalphalangeal, metacarpal phalanges

21

Saddle examples

Carpometacarpal

22

Ball and socket

Glenohumeral, coxal

23

Articular capsule

Has a synovial membrane and synovial fluid

24

Synovial membrane

Connective tissue

25

Synovial fluid

Cells of the membrane make this

26

Accessory structures of synovial joint

1. Menisci and fat pads
2.ligaments

27

Meniscus

Fibrocartilage, channels fluid within the joint, like a sponge, shock absorber

28

Fat pad

Fills space when bones move apart, insulated, prevents injury

29

Intrinsic ligaments

Inside the capsule

30

Extrinsic ligament

Outside of the capsule

31

Sprain

Portion of lig. Torn, but entire joint maintains integrity

32

Bursa

Fluid filled pockets, form where tendons/lig. Rub against other tissues

33

Bunion

Most common form of bursitis, great toe, also "housemaid's knee" or "student elbow"

34

Luxation or dislocation

Complete slippage of bone out of joint

35

Subluxation

Partial slippage of bone out of joint

36

Ankylosis

Complete bony fusion of the joints due to fibroblast activity

37

Rheumatoid arthritis

Autoimmune disease, inflammation of capsule

38

Osteoarthritis

Ages 60+, wear and tear of articulate cartilage cause thickening of capsule

39

Gouty arthritis

Crystals form in synovial fluid, usually calcium salts
