What is Articulation(joint)?

A place where bones meet

1

What are the three classes of joints based on structure?

1.) Fibrous
2.) Cartilaginous
3.) Synovial

2

Describe the fibrous joint

No joint cavity, held together with fibrous C.T.

3

Describe the Cartilaginous joint

No joint cavity, held together with cartilage

4

Describe the Synovial joint

Has joint cavity, held together by ligaments

5

Name the three classes of joints according to the amount of movement they permit.

1.) Synarthrosis: immovable joint
2.) Amphiarthrosis: slightly movable
3.) Diarthrosis: Freely movable

6

Sutures between skull bones are examples of

Synarthrotic

7

Discs between vertebrae are examples of

Amphiarthrotic

8

Attachment of a tooth to its socket in the mandible or maxilla is

Synarthrotic

9

More mobile that a suture but less mobile than a joint like elbow is

Amphiarthrotic

10

The symphysis pubis is an example of

Amphiarthrotic

11

The distal end of the tibia/fibula is an example of

Amphiarthrotic

12

The epiphysial plate in growing bone is an example of

Synarthrotic

13

Hyaline cartilage that covers ends of articulating bones

Articular cartilage

14

It lubicates the joints and nourishes the cartilage

Synovial fluid

15

Inner layer of the articulate capsule that produces synovial fluid

Synovial membrane

16

Pad of cartilage to help stabilize the joint

Meniscus

17

Together these form the articulate capsule

Fibrous capsule and synovial membrane

18

Fluid-filled sac that cushions movements

Bursa

19

The joint allowing for the greatest degree of movement

Ball-and-socket

20

Flat surfaces of the carpals or tarsals move across each other

Gliding

21

The joint at the wrist between the radius and carpals

Condyloid

22

Moves in a single plane at the knee or elbow

Hinge

23

He joint between the carpals and the metacarpal of the thumb

Saddle

24

The rounded head of the radius moves within the radial notch of the ulna

Pivot

25

Movement of the bone around its own axis

Rotation

26

Movement away from the midline of the body

Abduction

27

Palm faces upward or forward

Supination

28

Downward movement of a body part

Depression

29

Movement toward the body midline

Adduction

30

Movement of the mandible or shoulder backward

Retraction

31

Turning the palm so it faces downward or backward

Pronation

32

Upward movement of a body part

Elevation

33

Movement of a distal end of a body part in a circle

Circumduction

34

Beyond the plane of extension

Hyperextension

35

Movement of the sole of the foot inward

Inversion

36

Movement of the foot so the toes point downward

Plantarflexion

37

How are arthritis and rheumatism related?

Arthritis is a form of rheumatism

38

"Wear and tear" arthritis causing deterioration of the articulate cartilage is...

Osteoarthritis

39

Displacement of the bone from its joint is..

Dislocation

40

Overstretching a muscle is a

Strain
