joints

Question 1

any point where two bones meet

Answer 1

joint

Question 2

science of joint structure, function and dysfunction

Answer 2

arthrology

Question 3

general classification of the joints on the base how freely the bones move (4)

Answer 3

1. Bony joint
2. Fibrous joint
3. Cartilagenous joint
4. Synovial joint

Question 4

bony joint

Answer 4

synostosis
formed by ossification of either fibrous or cartilagenous joints

cranial bones, long bones with age. first rib and sternum

Question 5

Fibrous joint

Answer 5

Synarthrosis
Adjacent bones are bound by collagen fibers that emerge from 1 bone, cross the space btw them and penetrate into the other.

Question 6

3 types of fibrous joints

Answer 6

1. Suture
2. Gomphoses
3. Syndesmoses

Question 7

suture. what is it plus 3 types of sutures

Answer 7

immovable or only slightly movable joint in skull

• serrate (coronal, sagittal, lambdoid)
• Lap or squamous (temporal and parietal)
• plate (butt) btw palatine processes of maxilla in the roof of the mouth.

Question 8

Gomphoses

Answer 8

tooth to socket by fibrous peridontal ligament (collagen)

moves a little or gives under stress of chewing

Question 9

syndesmoses

Answer 9

relatively long collagenous fibers

btw radius and ulna - interosseous membrane - allows pronation and supination

Question 10

What are cartilagenous joints and 2 types

Answer 10

Amphiarthrosis
two bones are linked by cartilage
1. synchondrosis
2.symphysis

Question 11

Synchondrosis

Answer 11

bound by hyaline cartilage
temporary joint btw epyphisis and diaphysis of a long bone in children (epiphyseal plate)
or first rib and sternum

Question 12

symphysis

Answer 12

bound by fibrocartilage

pubic symphysis, btw bodies of vertebrae

Question 13

synovial joints

Answer 13

Diarthroses
can be multiaxial
monoaxial
biaxial
