The Muscular System
Today you will learn about:
The different types of muscle.
The structure of muscles.
The location of major muscles.
Types of muscle fibres.
How muscles work in pairs.
Found within your organs e.g. in your intestines
Found only in the heart
Found in muscles that allow us to move
Where are they found?
Where is it found?
Where can we find an example of each of these types of muscles?
What characteristics makes them different?
Where is it found?
Not under our conscious control – we don’t decide when to move them
Under conscious control – you can decide when to move them
Never stops working
Tendons attach the muscle to a bone. The fibres are strong and elastic.
Muscles are made of bundles of fibres which are enclosed in connective tissues.
TASK - Add labels to your diagram
TASK - Label the diagram
Find out what is the difference between a muscle origin and insertion?
Muscles can only create
movement in one
only pull a bone into a
new position, they
cannot push it back.
This means that at every
joint there must be
2 muscles to allow movement
Muscles work in pairs
When one muscle contracts (works) the opposing muscle relaxes this is known has antagonistic pairs.
The muscle that contracts to produce the movement is known has the prime mover.
Other muscle will assist the prime mover by contracting at the same time and these are called synergists.

How Muscles Work 6
Can you think of another pair of muscles and an exercise where they are used?
There are two basic types of muscle fibre.
Tend to favour
Tend to favour power
and strength activities
Copy the diagram into your book.
Muscle fibre percentages are genetically determined and vary between people.
Qs. How can improved muscle function improve performance?
Qs. What could we suggest about different people’s muscle fibre types and the activity they perform?
Swimmer pulling through the water
Sprinting / jumping
Jump to head a ball
Take off for long / high jump
Somersault in trampolining
Putting the shot
Tuck jump gymnastics
Ball toss when serving in tennis
Hockey player reaching forward to intercept a ball
Preparation of a set shot in b’ball
Complete tasks set in class and task sheet 4 muscles and activity.
