First Aid/Emergency Illness

2. Function of the Skeletal System
Framework that supports the body and protects vital organs.
Providing movable levers which the muscles can pull to move different parts of the body.
Bone marrow produces red and white blood cells
Storehouse for minerals, calcium and phosphorous

3. Structure
Information
206 Bones (Adult)
Axial – 80
Appendicular – 126

4. Structure Cont. Types of Bones Types of Joints Ball & Socket Hinge
Long
production of red/white blood cells: humerus and femur
Short
wrist and ankles
Flat
protective: skull and ribs
Irregular
complex shape/protection: vertebrates
Types of Joints
Ball & Socket
Hinge
Pivot
Condyloid
Sliding/Gliding
Saddle

5. Structure Cont.. Ligaments connective tissue that holds bone to bone
Tendons
connective tissue that attaches muscle to bone
Cartilage
strong flexible connective tissue; provides smooth movement and cushions joints

6. Diseases/Disorders
Osteoporosis – condition following menopause, lack of calcium absorption
Scoliosis/Lordosis/Kyphosis – abnormal curves of the vertebras
Arthritis – swelling and stiffness in bone joints
Bone Cancer – a secondary illness as a result of another cancer that has spread
Gout – metabolic disorder where a build-up of uric acid
Ricketts – vitamin D/calcium deficiency

7. First Aid & Emergency Illness
Fractures
Open/Compound
Closed/Simple
Dislocations
Bone slips from normal position in joint
Sprains
Stretching or tearing of the ligaments in a joint

8. First Aid Response Fractures Call 911 – Seek medical treatment
Immobilize area using a “splint” if trained
If open, implement steps to control bleeding

9. First Aid Response Sprains P – Protection R – Rest I – Ice
C – Compression
E – Elevation

10. First Aid Response Dislocation Call 911 – seek medical treatment
Use sling for shoulder injury
Keep extremity close to body

11. General Care
Calcium – eat foods with this to build strong bones; found in dairy and green leafy vegetables.
Phosphorous – combines with calcium to make bones more rigid
Resistance Exercise – increase bone density and muscle conditioning
Cardiovascular – make heart pump more efficient

12. Other Systems Muscular Together allows body to move Lymphatic
Production of white blood cells
Circulatory
Production of red blood cells and platelets
