Question 1

Name types of joints

Answer 1

fibrous
cartilaginous
synovial

Question 2

Fibrous

& example

Answer 2

immovable and interlocking bones joined by fibrous tissue that is rich in collagen fibres

• cranium

Question 3

Cartilaginous

& example

Answer 3

slightly moveable and the bones are joined together by cartilage

• manubriosternal joint

Question 4

Synovial

Answer 4

freely moveable and are the most common type of joint in the body

• pateellofemoral (knee) joint

Question 5

Name the types of synovial joints

Answer 5

• gliding/plane joints
• hinge joints
• pivot joints
• saddle joints
• ball and socket joints
• condyloid/ellipsoid joints

Question 6

What are the characteristics of synovial joints?

Answer 6

• ends of bone covered with hyaline
  cartilage
• surrounded by a fibrous capsule
• capsule lined by a synovialmembrane that secretes synovial
  fluid for lubrication
• enclosed by ligaments for stability

Question 7

Gliding/plane joint example

Answer 7

acromioclavicular joint

Question 8

Hinge joint example

Answer 8

knee

Question 9

Pivot joint example

Answer 9

atlanto-axial joint

Question 10

Condyloid/ellipsoid joint example

Answer 10

metacarpophalangeal joint (knuckles)

Question 11

Saddle joint examples

Answer 11

carpometacarpal joint (thumb)

Question 12

Ball and socket joint examples

Answer 12

hip

Question 13

Gliding/plane joint function

Answer 13

allow 2 bones to slide past each other

Question 14

Hinge joint function

Answer 14

bones can only move through flexion and extension

Question 15

Pivot joint function

Answer 15

allows rotation around an axis

Question 16

Ball and socket joint function

Answer 16

allows movement in almost any direction- the greatest amount of joint movement in body

Question 17

Condyloid/ellipsoid joint function

Answer 17

similar to ball and socket, but allow lesser degree of movement

Question 18

Saddle joint function

Answer 18

similar to ball and socket/saddle, but without rotational movement
