1

What is a joint?

Where 2 or more bones meet

2

What are the 3 main types of joints?

Fibrous
Cartilaginous
Synovial

3

How much movement do Fibrous joints allow?

None

4

How much movement do Cartilaginous joints allow?

Very little

5

How much movement do Synovial joint allow?

Varied wide range

6

What are the 3 types of Fibrous joints?

Sutures
Gomphoses
Syndesmoses

7

Where are Suture joints found?

Inbetween sections of the skull

8

Where are Gomphoses joints found?

Where the teeth articulate with the Maxillae (upper) and Mandible (lower)

9

Where are Syndesmoses joints found?

Where bones are held together by interosseus membranes eg middle radioulnar joint

10

What are the 2 types of Catilaginous joints?

Synchondroses (Primary)
Symphyses (Secondary)

11

What do Synchondroses cartilaginous joints have?

Minimal/no movement
Hyaline cartilage
eg sterno-costal joint

12

What are Synchondroses cartilaginous joints?

A temporary joint with no movement
Joint between diaphysis and epiphysis of long growing bone

13

What do Symphyses cartilaginous joints have?

The end of bones are covered with Hyaline cartilage
Bones joined by disc of fibrocartilage and surrounding ligaments
Limited movement

14

What is an example of a Symphyses cartilaginous joint?

The joints between the vertebral bodies

15

What are the types of Synovial joints?

Hinge
Saddle
Plane
Pivot
Condyloid
Ball & Socket

16

What do Hinge Synovial joints allow?

Flexion and extension only
eg elbow joint

17

What do Plane Synovial joints allow?

Gliding/Sliding movements

18

What do Pivot Synovial joints allow?

Rotation
eg proximal radioulnar joint

19

What do Condyloid Synovial joints allow?

Flexion
Extension
Adduction
Circumduction
eg metacarpelphalangeal joint

20

What do Ball & Socket Synovial joints allow?

Movement in several axis
eg Hip and shoulder joints

21

What does the stability of joints rely on?

Shape, size & arrangement of articulating surfaces
Ligaments
Tone of muscles
