1

Joints or Articulations are a point of contact between:

- 2 or more bones
- bones & cartilage
- bones & teeth

2

List the three different types of joints:

- fibrous joints
- cartilaginous joints
- synovial joints

3

State the different functions of joints

- Synarthrodial (immoveable)
- Amphiarthrodial (slightly moveable)
- Diarthrodial (freely moveable)

4

Describe the structure of synovial joints

- surrounded by an articular or joint capsule
- capsule is lined with synovial fluid
- synovial fluid fills the synovial cavity
- synovial fluid reduces friction

5

Describe structures involved in stabilising a joint

- ligament joins bone to bone and stabilises joint
- tendons attach muscle to bone

6

Discuss the difference between the male and female pelvis

Female
- wide and shallow
- adapted for child bearing, more moveable, projects inferiorly
Male
- narrow and deep
- adapted for support of a heavier build & stronger muscles.
- less moveable, projects anteriorly

7

Why is the metal head not fully developed when ready for birth?

To allow for slight compression during birth

8

Describe age related changes in bones and joints

In children and adolescents: Formation exceeds reabsorption

In young adults: Both are balanced

In adults: reabsorption exceeds formation

9

List the different type of synovial joints

- A ball in socket joint
- Hinge joint
- pivot joint
- saddle joint

10

Explain what a cartilaginous joint is

Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint.

11

Explain what a fibrous joint is

These joints have no joint cavity and are connected via fibrous connective tissue.
e.g.: sutures between skull bone
