Q

Sesamoid bone is encapsulated in…

A

a tendon
ex: patella

20
Q

Where is the epiphysis located?

A

at the end of long bone

21
Q

What does articular cartilage cover?

A

Epiphysis

22
Q

What’s the primary function of the epiphysis?

A

Friction reduction b/c its needs to stay as smooth as possible

23
Q

What is articulation?

A

connection of two bones at the joint

24
Q

What are the 3 major classifications of joints?

A

Synarthrodial, Amphiarthrodial, Diarthrodial

25
Q

Synarthrodial Joints

A

immovable joints
ex: suture such as skull sutures

26
Q

Amphiarthrodial Joints

A

slightly movable joints
ex: distal tibiofibular joint

27
Q

Diarthrodial/Synovioal Joints

A

Freely movable joints; secretes synovial fluid to lubricate joint cavity and supplies nutrition

28
Q

Static Stability

A

bone, cartilage, ligaments, capsule

29
Q

Dynamic stability

A

muscles and tendons

30
Q

What’s the name for specialized cartilage in the Synovial joints?

A

Fibrocartilage

31
Q

What’s the two functions of Fibrocartilage?

A
  1. Shock absorption
  2. Increasing stability
32
Q

Degrees of Freedom is determined by?

A

The number of planes of motion

33
Q

What are the 6 types of diarthrodial/synovial joints?

A
  1. Arthodial
  2. Ginglymus
  3. Trochoid
  4. Condyloid
  5. Enarthrodial
  6. Sellar
34
Q

What do arthrodial joints do?

A

Only gliding motions occur

35
Q

What do Ginglymus joints do?

A

Hinge

36
Q

What do Trochoid Joints do?

A

only allow rotation

37
Q

What do Condyloid joints do?

A

metacarpophalangeal joint; ball and socket joint

38
Q

What do enarthrodial joints do?

A

They’re the most movable in the body; has all 3 planes of motion

39
Q

What do sellar joints do?

A

Only TWO in the body; 1st carpometacarpal joint in the thumb (not whole thumb)

40
Q

What’s another name for physiological motion/movement?

A

Osteokinematic motion

41
Q

Examples of Osteokinematic motion are…?

A

Flexion, extension, abduction, adduction, and rotation

42
Q

What’s another name for Accessory motion/movement?

A

Arthrokinematic motion

43
Q

Examples of Arthrokinematic motion are…?

A

Roll, spin, glide, and slide

44
Q

Arthrokinematic motion must occur for…?

A

Osteokinematic motion to occur

45
Q

When a joint is unstable, it negatively impacts what?

A

Arthrokinematic motion (which impacts osteokinematic motion)

46
Q

What’s the purpose of Arthrokinematic motion?

A

to keep the two articulating surfaces in contact with each other

47
Q

What’s the purpose of Osteokinematic motion?

A

Occurs only in planes
