Flashcards in Articulations Deck (28):
1

Joints

Where two or more bones come together
Articulations
Move built

2

Synarthrosis

Immovable

3

Amphiarthrosis amphi(between)

Slightly movable

4

Diarthrosis

Freely movable

5

Bony fusion

Fusion of frontal bone

6

Fibrous joint

Skull sutures

7

Cartilaginous joint

Pubic symphysis

8

Synovial joint

Ball and socket hinge joints

9

Sutures (joints found in skull) fibrous joint

Bones are interlocked together

10

Gomphosis (joint between teeth and jaw bones)

Periodontal ligaments of teeth ( TOP all of teeth in maxillae) teeth anchored in socket fibrous joint (actually a ligament) periodontal ligament

11

Synchondrosis (joint with epiphysis of bone)

Binds with the diaphysis to epiphysis (syn locked together) chondro( cartilage) bone cartilage bone hyline

12

Synostosis(joint between two fused bones)

Fusion of three coxal bones (syn fused) osteo (bone) illium ishium pubis (il, is, pub)

13

Amphiarthroses slightly movable
Syndesmosis (ligaments that connect two bones but limit their motion)

Between radius and ulna
Tibula fibula

Length and tightness of ligament allow more or less movement

14

Symphysis (bones are separated by a wedge or pad of cartilage)

Between the pubic bones of the two coxal bones cartilaginous... bone cart( bone
Fibrous cartilage (shock absorber) or vertebral column

15

Diarthroses (freely movable)

Synovial Joints
-typically at the end of long bones
All the joints in the limbs
Bone (open space with fluid) bone

16

6 basic characteristics synovial

Joint capsule (
The presence of articular cartilage (dense irregular tissue)
The presence of articular cartilages
A joint cavity with synovial fluid
A synovial membrane
Accessory structures (cartilage, ligaments, tendons, bursae)
Sensory nerves and blood vessels

17

Synovial fluid

-lubricates the surfaces of the articular cartilages and reduces friction
-nourishes the chondrocytes by entering and exiting the articular cartilages due to the forces acting on the joint
Acts as shock absorber

18

Accessory structures synovial joints

Menisci (pads of cartilage inside joint) fibrocartilage
Ligaments (dense regular)bone to bone
Tendons (dense regular)muscle to bone
Bursae around joint to protect structures

19

Linear movement

Two bones gliding past
Carpal carpal
Tarsal tarsal
Clavical sternum

20

Angular movement

Abduction/ adduction
Flexion/extension

_______o_________ extension increasing angle
180deg

21

Rotational movements

Pronation
Supinate

Shoulder and hip

22

Circumduction

MAKING CIRCLE
CERVICAL vertebrae saying no

23

Eversion/inversion

In- twist meadially
Only in foot

24

Dorsiflexion/plantar flexion

Dorsi- curling towards you
Plantar- bottom
Only inthe foot

25

Lateral flexion

Flexing to the sides
Spine

26

Retraction protraction

Dont change the angle
Protraction pushing mandible forward
Protraction pulling it back

Jaw shoulder

27

Opposition


Pollex directly opposing other fingers

28

Depression elevation

NO angle change
Like opening mouth depression
Putting jaw up elevation
Shrugging shoulders
