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.
