Answer 1

Where two or more bones come together
Articulations
Move built

Question 2

Answer 2

Immovable

Question 3

Amphiarthrosis amphi(between)

Answer 3

Slightly movable

Question 4

Diarthrosis

Answer 4

Freely movable

Question 5

Bony fusion

Answer 5

Fusion of frontal bone

Question 6

Fibrous joint

Answer 6

Skull sutures

Question 7

Cartilaginous joint

Answer 7

Pubic symphysis

Question 8

Synovial joint

Answer 8

Ball and socket hinge joints

Question 9

Sutures (joints found in skull) fibrous joint

Answer 9

Bones are interlocked together

Question 10

Gomphosis (joint between teeth and jaw bones)

Answer 10

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

Question 11

Synchondrosis (joint with epiphysis of bone)

Answer 11

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

Question 12

Synostosis(joint between two fused bones)

Answer 12

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

Question 13

Amphiarthroses slightly movable

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

Answer 13

Between radius and ulna
Tibula fibula

Length and tightness of ligament allow more or less movement

Question 14

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

Answer 14

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

Question 15

Diarthroses (freely movable)

Answer 15

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

Question 16

6 basic characteristics synovial

Answer 16

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

Question 17

Synovial fluid

Answer 17

-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

Question 18

Accessory structures synovial joints

Answer 18

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

Question 19

Linear movement

Answer 19

Two bones gliding past
Carpal carpal
Tarsal tarsal
Clavical sternum

Answer 21

Pronation
Supinate
‘
Shoulder and hip

Question 22

Circumduction

Answer 22

MAKING CIRCLE

CERVICAL vertebrae saying no

Question 23

Answer 24

Dorsi- curling towards you
Plantar- bottom
Only inthe foot

Question 25

Lateral flexion

Answer 25

Flexing to the sides

Spine

Question 26

Retraction protraction

Answer 26

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

Jaw shoulder

Question 27

Opposition

Answer 27

Pollex directly opposing other fingers

Question 28

Depression elevation

Answer 28

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