Structure of synovial joint and muscle attachment

1. Lloyd Dean
Skeletal System

2. Objectives
By the end of the lesson you should be able to:
Describe the structure of a synovial joint
State the muscle attachments to the skeleton
Complete relevant workbook activities on above topics

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?
How would your answer impact your warm up, for example?

6. Muscle Attachment
Muscles need to attach to bones
These points are called O_____ & I________
How do we distinguish between each?
Origin is the attachment on the bone that does not move
Insertion is the attachment on the bone that does move
