Joints or Articulations are a point of contact between:

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


List the three different types of joints:

- fibrous joints
- cartilaginous joints
- synovial joints


State the different functions of joints

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


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


Describe structures involved in stabilising a joint

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


Discuss the difference between the male and female pelvis

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


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

To allow for slight compression during birth


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


List the different type of synovial joints

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


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.


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
