Articulations

Joints

1

Joints are

Where 2 or more bones come together

Slight to no movement or freely movable

2

Structural classification

Based on MATERIALS found between bones

3

Functional classification

Based on MOVEMENT between bones

4

Fibrous joints (3)

1. Not true joint
2. Sutures of the skull
3. Very slight motion-syndesmosis

5

Syndesmosis

End of tibia, fibula, wrist, ulna

Very slight movement

6

Cartilage is

Not a true joint

7

Gomphosis - cartilage

Gums locked in jaw

8

Synchroidrosis - cartilage

Cartilage around sternum

9

Symphysis - cartilage

Intervertebral discs

Slight grinding motion

10

Synovial joints are

True joints

Sac with fluid inside surrounding joints

11

Dyarthrosis

Freely moveable

12

Uniaxial

One plane

13

Biaxial

Two planes

14

Synovial joint fluid gets ____ the more you move around

Thinner

Waking up- stiff
Joints warm up- normal

15

Synovial structures (3)

1. Synovial capsule
2. Bursa
3. Tendon sheath

16

Bursitis

Inflammation of bursa

17

Tendinitis

Inflammation of a tendon

18

Tenoshnovitis

Inflammation of a tendon sheath

19

Bursa

Pillow like joint, fluid filled

20

Nonaxial synovial joint

Gliding movement in no particular plane

21

Gliding joints

Flat articular surfaces allow least movement

Between carpals and tarsals

22

Uniaxial

Movement in a single plane

One motion, knee, elbow

23

Hinge joints

Moves up or down, right or left only

24

Flexion

Working muscle

25

Extension

Relaxing muscle

26

Pivot joints

One movement

Ex. Atlas and axis

27

Biaxial

Movement in two planes

28

Saddle joints

Pollex of thumb or "saddle joint" of thumb

Can move all around

29

Multiaxial

Movement in many planes

Hip, shoulder

30

Ball and socket joints

Shoulder and hip

31

Felxion

Joint angle DECREASES

32

Extension

Joints angle INCREASES

33

Dorsiflexion and plantar flexion

Up and down movement of the foot

34

Abduction

Movement of limb AWAY FROM the body

35

Adduction

Movement of limb TOWARDS the body

36

Supination position

Palm up, cupping soup

37

Pronation position

Palms facing down

38

Inversion

Turning in

39

Eversion

Turning out (foot for ex)

40

Osteoarthritis

Cartilage at a joint wears down, with age

41

Rheumatoid arthritis

Autoimmune inflammatory arthritis

Severe pain, swelling, deformation of the joint

42

Kyphosis

Hunch back

43

Lordosis

Sway back

Tummy pushed out

44

Scoliosis

Abnormal lateral curve of spine
