Understanding the Skeletal System: Functions, Parts, and Care

The skeletal system serves five major functions: providing a framework, allowing movement, protecting vital organs, producing blood cells, and storing essential minerals. It comprises two main parts: the axial skeleton (80 bones, including the skull, spine, ribs, and sternum) and the appendicular skeleton (126 bones, including arms, legs, and hips). Understanding the types of bones—long, short, flat, and irregular—along with joint types and connective tissues is vital. Proper care through nutrition, exercise, and safety practices is crucial for maintaining a healthy skeletal system.

  1. SKELETAL SYSTEM 5 MAJOR FUNCTIONS

  2. FUNCTION • PROVIDES A FRAMEWORK

  3. FUNCTION • ALLOWS MOVEMENT

  4. FUNCTION • PROTECTS VITAL DELICATE ORGANS

  5. FUNCTION • PRODUCES RED AND WHITE BLOOD CELLS

  6. FUNCTION • STORES ESSENTIAL MINERALS CALCIUM PHOSPHORUS

  7. SKELETAL SYSTEM2 MAIN PARTS • AXIAL • APPENDICULAR

  8. SKELETON • AXIAL • CENTER OF SKELETON (80 BONES) • SKULL • SPINE • RIBS • STERNUM

  9. SKELETON • APPENDICULAR (126 BONES) • INCLUDES BONES OF THE: • SHOULDERS • ARMS • LEGS • HIPS • HAND • FEET • HELPS YOU PERFORM MOVEMENT

  10. SKELETON TYPES OF BONES

  11. TYPES OF BONES • LONG BONES- • SHORT BONES- • FLAT BONES- • IRREGULAR BONES-

  12. TYPES OF BONES • LONG BONES • FOUND IN • ARMS • LEGS • HANDS • FEET

  13. TYPES OF BONES • SHORT BONES ARE AS BROAD AS THEY ARE LONG FOUND IN • WRISTS • ANKLES

  14. TYPES OF BONES • FLAT BONES • PROTECT VITAL ORGANS • RIBS • SKULL • PELVIS

  15. ANATOMY OF A LONG BONE • DIAPHYSES-SHAFT OF LONG BONE • EPIPHYSES- END OF LONG BONE COME TOGETHER TO FORM JOINTS • APOPHYSES- WHERE MUSCLES ATTACH TO THE BONE

  16. Types of Joints • Ball and socket • Shoulder • hip

  17. Types of joints • Hinge • Elbow • Knee • Fingers • Toes

  18. Types of joints • Pivot • Neck • forearm

  19. Types of joints • Gliding joints • Spine • Wrist • Ankle

  20. Types of Connective tissue • Ligament- connects bone to bone • Tendon- connects muscle to bone

  21. Types of Connective Tissue • Cartilage- strong, flexible and resilient: • cushions • Adds support • Allows smooth movement.

  22. Problem of the skeletalsystem • Osteoporosis • Brittle bone disease • Bones lose density • Most common in older females of slight frames

  23. Fracture • Any break in a bone

  24. Fracture • Simple fracture- closed fracture • Bone does not break the skin

  25. Fracture • Compound or open fracture- injury is complicated by a open wound to skin.

  26. Scoliosis • A lateral curve in the spine • Unknown cause • Can cause deformity if untreated • Treatment • Exercises • Brace • surgery

  27. Treatment • Scoliosis EXERCISE (mild) Surgery (severe) Brace (moderate)

  28. Leukemia • Cancer of the white blood cells that are produced in the bone marrow

  29. Dislocation • When a joint is displaced out of its position • Results in deformity and pain

  30. sprain • A stretching or tearing of the ligaments around a joint

  31. Tendonitis • An inflammation of the tendon • Pain • Swelling • Redness • Stiffness

  32. Care of the skeletal system • Eat a varied diet high in calcium • Weight bearing exercises • Protective equipment • Avoid risky behaviors • Plenty of rest
