Skeletal System

2. Objectives
By the end of the lesson you should be able to:
 List the structures of a synovial joint
 Label a diagram of a synovial joint correctly
 State the long term benefits of exercise on bone
and synovial joints
 Supply short term benefits of exercise on bone
and synovial joints

3. Structures of a Synovial Joint
 Ligaments
 Articular Cartilage
 Joint Cavity
 Synovial Membrane
 Synovial Fluid

4. Structures of a Synovial Joint
 Ligaments – Joint bone to bone
 Articular Cartilage – Covers the ends of bone
 Joint Cavity – “Hole” filled with synovial fluid
 Synovial Membrane – Found inside the joint capsule and creates
synovial fluid
 Synovial Fluid – Nourishes joint, removes waste debris and lies in
joint cavity
 How can exercises improve the function of a synovial joint?

6. Short Term Effects Long Term Effects
Bones •Can become sore, stressed and
damaged after heavy weight
bearing exercise
•Bone Density increased –
Reduced chance of osteoporosis
•Arthritis likelihood reduced
•More strong
Synovial Joints •Synovial fluid becomes less
solidified
•Can become sore, stressed and
damaged after heavy weight
bearing exercise
•Cartilage and surrounding tissues
become stronger
•Synovial fluid becomes more
lubricated
•Increased flexibility
•Become more stabilised
