MUSCLES AND MOVEMENT

H/W – due by next Thursday (latest).Thursday (latest). Complete the exam paper coving all topics thus far. Write answers

in your books in full sentences!!! Any h/w not completed must be done.

The muscles in the body each fall into one of three groups:

1.VOLUNTARY or SKELETAL MUSCLES- these muscles are under the control of our will. All these muscles are attached to the skeleton.

These muscles make up about 40% of our body weight. Examples are the Triceps, Biceps, Deltiods (shoulders), Quadriceps and Hamstrings.

•These muscles are usually long and thin.

•They are usually paired up e.g. BICEP and TRICEP muscles.

•One muscle bends the joint (FLEXION) and the other straightens it (EXTENSION).

•These pairs of muscles are called ANTAGONISTS.

•In picture>>>>>>>>>>>>>>>>>>>>>

•Biceps are flexing (fat), triceps are relaxing (thin).

2. INVOLUNTARY MUSCLES- These muscles, as the name suggests, are not under our control.

They can be found in the organs of the body, such as the Digestive and Circulatory systems, and they contract and relax automatically.

3. CARDIAC MUSCLE- is found in the wall of the heart.

WHAT ARE THE NAMES OF THE MUSCLES WE NEED TO LEARN ?

1.DELTOID

2.PECTORALS

3.BICEPS

4.TRICEPS

5.ABDOMINALS

6.QUADRICEPS

8. LATISSIMUS DORSI

9. GLUTEALS

10. HAMSTRINGS

11. GASTROCNEMIUS

Now using slide 10 for help, try the test below. Aim to get at least 7/10

GIVE ONE EXAMPLE IN SPORTS THAT USE THESE MUSCLES? Slides 10-13 may help.

In rugby, your deltoids contract when you make a rugby tackle.

If you finish these tasks within the lesson (those wanting to get good grades for PE), then open the lesson ten slide we started

last week and read through slides 29 onwards on movement.

Don’t print straight away!! Go to file, print. Where it says “print what”, select handouts. This way, you print 6 slides on each page ;-)
