16
Q

What are the 6 Diarhrosis joints

A

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

17
Q

Ex of gliding joints

A

Between articulate processes of vertebrae, intercarpal, intertarsal

18
Q

Ex of hinge joint

A

Elbow, knee, interphalangeal

19
Q

Pivot joint

A

Alanto-Axial, proximal radioulnar

20
Q

Ellipsodial joints

A

Radiocarpal, metatarsalphalangeal, metacarpal phalanges

21
Q

Saddle examples

A

Carpometacarpal

22
Q

Ball and socket

A

Glenohumeral, coxal

23
Q

Articular capsule

A

Has a synovial membrane and synovial fluid

24
Q

Synovial membrane

A

Connective tissue

25
Q

Synovial fluid

A

Cells of the membrane make this

26
Q

Accessory structures of synovial joint

A
  1. Menisci and fat pads

2. ligaments

27
Q

Meniscus

A

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

28
Q

Fat pad

A

Fills space when bones move apart, insulated, prevents injury

29
Q

Intrinsic ligaments

A

Inside the capsule

30
Q

Extrinsic ligament

A

Outside of the capsule

31
Q

Sprain

A

Portion of lig. Torn, but entire joint maintains integrity

32
Q

Bursa

A

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

33
Q

Bunion

A

Most common form of bursitis, great toe, also “housemaid’s knee” or “student elbow”

34
Q

Luxation or dislocation

A

Complete slippage of bone out of joint

35
Q

Subluxation

A

Partial slippage of bone out of joint

36
Q

Ankylosis

A

Complete bony fusion of the joints due to fibroblast activity

37
Q

Rheumatoid arthritis

A

Autoimmune disease, inflammation of capsule

38
Q

Osteoarthritis

A

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

39
Q

Gouty arthritis

A

Crystals form in synovial fluid, usually calcium salts
