Skeletal System· Parts of the skeletal system
· Bones (skeleton)
· Joints
· Cartilages
· Ligaments (bone to bone)(tendon=bone to muscle)
· Divided into two divisions· Axial skeleton- skull, spinal column
· Appendicular skeleton – limbs and girdle
![Page 17: Fit and Healthy Year 9 – Unit B. Do Now: What types of activities do you regularly do for exercise?](https://reader033.vdocument.in/reader033/viewer/2022052606/5a4d1afb7f8b9ab059983b0c/html5/thumbnails/17.jpg)
Functions of Bones·Support of the body·Protection of soft organs·Movement due to attached skeletal muscles·Storage of minerals and fats·Blood cell formation
![Page 18: Fit and Healthy Year 9 – Unit B. Do Now: What types of activities do you regularly do for exercise?](https://reader033.vdocument.in/reader033/viewer/2022052606/5a4d1afb7f8b9ab059983b0c/html5/thumbnails/18.jpg)
Bones of the Human Body·The skeleton has 206 bones·Two basic types of bone tissue
·Compact bone·Homogeneous
·Spongy bone·Small needle-like pieces of bone·Many open spaces
![Page 19: Fit and Healthy Year 9 – Unit B. Do Now: What types of activities do you regularly do for exercise?](https://reader033.vdocument.in/reader033/viewer/2022052606/5a4d1afb7f8b9ab059983b0c/html5/thumbnails/19.jpg)
Classifying Bones• Bones are classified by their shape: 1.Long- bones are longer than they are wide (arms,
legs)2.Short- usually square in shape, cube like (wrist, ankle)3.Flat- flat , curved (skull, Sternum)4.Irregular- odd shapes (vertebrae, pelvis)

Names of the Bones

Do Now:• Look at your results from yesterdays experiment. What conclusion
can you make about strength and bone length?
![Page 22: Fit and Healthy Year 9 – Unit B. Do Now: What types of activities do you regularly do for exercise?](https://reader033.vdocument.in/reader033/viewer/2022052606/5a4d1afb7f8b9ab059983b0c/html5/thumbnails/22.jpg)
Muscles• Responsible for movement• Skeletal muscles cause the skeleton to move at joints• They are attached to skeleton by tendons.
![Page 23: Fit and Healthy Year 9 – Unit B. Do Now: What types of activities do you regularly do for exercise?](https://reader033.vdocument.in/reader033/viewer/2022052606/5a4d1afb7f8b9ab059983b0c/html5/thumbnails/23.jpg)
Muscles!• The ability to move is an essential activity of the human body • ½ our body weight comes from muscles• Consists of over 600 individual muscles.• 3 purposes:
• Body movement• Body shape• Body heat (maintain temp.)
![Page 24: Fit and Healthy Year 9 – Unit B. Do Now: What types of activities do you regularly do for exercise?](https://reader033.vdocument.in/reader033/viewer/2022052606/5a4d1afb7f8b9ab059983b0c/html5/thumbnails/24.jpg)
No Pushing!• Muscles are either contracted or relaxed• When contracted the muscle exerts a pulling force, causing it to
shorten• Since muscles can only pull (not push)
![Page 25: Fit and Healthy Year 9 – Unit B. Do Now: What types of activities do you regularly do for exercise?](https://reader033.vdocument.in/reader033/viewer/2022052606/5a4d1afb7f8b9ab059983b0c/html5/thumbnails/25.jpg)
3 Types of Muscles• Body movements are determined by three types of muscles
• Smooth (involuntary) – cannot be controlled by will.• Cardiac – control the contractions of the heart.• Skeletal (Voluntary) – can be controlled by will.

Muscle Fibres• A single muscle e.g. biceps contains approx. 1000 muscle fibres.• These fibres run the whole length of the muscle• Muscle fibres are joined together at the tendons
