  1. Skeletal System • National Standards 1.8.1 Analyze the relationship between healthy behaviors and personal health • Standard 10.1 Concepts of Health • Growth and Development • Structure and Function of Major Body Systems • Health Problems • Standard 10.2 Healthful Living • Health practices and well-being

  2. Functions 1. Movement – With help of the muscular system 2. Framework – Supportive Structure for the Body 3. Protection – Protects Internal Organs Give me an example 4. Storage – Minerals like Calcium & Phosphorus 5. Production– Produces blood cells in the Red Marrow of the Long Bones

  3. Axial Skeleton Definition: Bones in the Mid-Line of the Body Like an Axis. . . like the Earth rotates on an Axis 1. Skull – Protects the Brain and Shapes the Face 2. Sternum – “Breast Bone” 3. Ribs – The “Cage” that protects the Lungs and Heart 4. Vertebrae – “The Spine” – Protects Spinal Cord Purpose: PROTECTION

  4. AppendicularSkeleton Bones that you can move Definition: away from the Mid-Line Like an appendage. . .Which is. . . a thing that is added or attached to something larger or more important. 1. Shoulders 4. Hips 2. Arms 5. Legs 3. Hands 6. Feet Purpose: Movement

  5. Bones

  6. Bones - Types Long Bones 1. 2. Short Bones 3. Flat Bones 4. Irregular Bones 5. Sesamoid Bones There are bones in the adult body 206

  7. Bones – Long Bones Purpose: To provide strength, structure, and mobility 1. Found in the Arms and Legs 2. Very Strong 3. Hollow tube, Filled with Red Marrow that produces blood cells

  8. Bones – Short Bones Purpose: To provide support and stability with little to no movement 1. These bones are as wide as they are long 2. Found in the Hands, Wrists, Feet and Ankles.

  9. Bones – Flat Bones Purpose: To Protect Vital Body Organs 1. They have a FLAT and THIN shape Found in Ribs, Skull & Pelvis 2.

  10. Bones – Irregular Bones Purpose: To Protect Spinal Cord 1. Don’t fit with any other types of bones Found in Vertebrae & Face 2.

  11. Bones – Sesamoid Bones Purpose: They Act like a pulley - They provide a surface for a tendon to slide over. 1. The Patella (Knee Cap)

  12. Quiz Next Class:MatchingWord bankSkeleton areasBone categories

  13. Joints

  14. Joints - Types Definition: The Point at which two or more bones meet Immoveable 1. 2. Slightly Moveable 3. Moveable

  15. Joints Immoveable - Bones in the Skull Slightly Moveable - Bones in the Vertebrae - Short Bones

  16. Joints – Moveable 1. Ball and Socket Joint: Hip & Shoulder 2. Pivot Joint: Neck and Radius 3. Saddle Joint: Thumb 4. Hinge Joint: Knee and Elbow 5. Gliding Joint: Hand and Foot 6. Ellipsoid Joint: Wrist and Ankle

  17. Joints – Moveable

  18. Joints – Moveable Gliding

  19. Supportive and Connective Tissues

  20. Cartilage Strong & Flexible material Definition: that has many functions Frame Structure - Nose and Ears 1. 2. Connective Tissue - Ribs to Sternum & Ribs to Vertebrae 3. Cushioning - Between Vertebrae and Knees Gliding Movement 4. - Allows smooth motion in moveable joints

  21. Ligaments Purpose: Connect Bone to Bone 1. A ligament is an elastic band of tissue that connects bone to bone and provides stability to the joint.

  22. Tendons Purpose: Connect Muscle to Bone 1. A tendon is a band of tissue that connects muscle to bone.

  25. Problems

  26. Fractures Definition: - A crack or break in a bone - Open vs Closed Fracture - Displaced vs Non-Displaced

  27. Posture Poor Posture - Causes: - Soreness and pain - Poor circulation - Negativity and stress - Digestive issues - Body image issues

  28. Scoliosis Definition: Curvature of the Spine Causes: 1. Could be Unknown 2. Poor Posture 3. Hereditary Treatments: 1. Exercise, Chiropractor 2. Brace 3. Surgery

  29. Scoliosis

  30. Diet Poor Diet – Lack of Calcium - Can lead to. . . Also. . .

  31. Osteoporosis Definition: Holes in the Bones Causes: 1. Loss of Calcium in the Bone Effect: 1. Bones become Weak Treatments: 1. Exercise 2. Proper Diet 3. Extra Calcium

  32. Osteomyelitis Inflammation of the Definition: Soft Inner Surface of the Bones Causes: 1. Bacterial Infection Effect: 1. Bones become Weak / Pain Treatments: 1. Antibiotics 2. Surgery

  33. Injuries A joint is twisted or Definition: receives too much pressure Sprain: Ligament is over-stretched or torn Effect: 1. Swelling / Pain Treatments: 1. RICE 2. Surgery

  34. Dislocation - A Bone slips out of its Joint

  35. Stress Fractures Definition: Tiny cracks in Bones Causes: 1. Overuse, repetitive strain 2. most common injuries in sports, especially for track and field athletes, gymnasts, dancers, tennis players, and basketball players. Treatments/prevent: 1. Stop Exercise/RICE 2. Proper Diet 3. Start slow/Proper shoes

  36. Skeletal Care

  37. Skeletal Care 1. Exercise - Weight Bearing Activity - Flexibility

  38. Skeletal Care 2. Diet • High in Calcium • milk, cheese and other dairy foods. • green leafy vegetables – such as broccoli, cabbage and okra, but not spinach. • nuts. • bread and anything made with fortified flour. • High in Phosphorus • Dairy, Fish, Meat, Nuts, Beans, & Whole Grains

  39. The End

  40. Negative Effects of Bad Posture
