Transcript The Skeletal System / Care and Problems of the Skeletal

Lesson 15.1 – 15.2





Living structure and framework in order to
move
Protection of vital organs (i.e. skull :: brain)
Calcium and Phosphorus storage
Production of red and white blood cells
What would happen if we didn’t have a
skeleton?

Axial Skeleton – skull, spine, ribs, vertebrae,
sternum
Appendicular Skeleton – everything else

Types of Bones

◦ Long Bones – diaphysis (middle), epiphysis (ends,
where blood cells are produced)
◦ Short Bones – equal in length and width
◦ Flat Bones – i.e. Skull, Scapula
◦ Irregular Bones – oddly shaped bones for specific
reasons






Ball-and-Socket – hip and shoulder
Hinge – elbow, knee, ankle, etc.
Pivot – 1 location, Base of Skull
Ellipsoidal – Curved spaces (wrist)
Ligament – connects bone to bone
Tendon – connects muscle to bone

Nutrition:
◦ Eat foods with Calcium, Vitamin D, and Phosphorus
 Milk (Calcium, Vitamin D)
 Beans, Whole Grains, Liver (Phosphorus)

Prevention
◦ Regular physical activity (weight-bearing)
◦ Protective gear

How would you explain to younger students
how to prevent bone injuries?
• Which bones do you see most commonly injured
and how?



Fracture – any type of break in a bone
Osteoporosis – condition with progressive
loss of bone tissue
Scoliosis – abnormal, lateral curvature of the
spine either from birth or early development



Dislocation – torn ligaments allow bone to
slip out of place
Bursitis – inflammation of fluid sac normally
used to reduce friction in a joint
Repetitive Motion Injuries – prolonged,
repeated movements
◦ Carpal Tunnel Syndrome is the most common
repetitive motion injury
