The skeletal system

  1. 1. The Skeletal SystemThe Skeletal System “Bones” (basically)“Bones” (basically) Here we go… Disclaimer: There are pictures in this presentation you will not be able to find, others you will. Make note of the information and move on.
  2. 2. The Functions of BonesThe Functions of Bones •Support •Storage (Fat, minerals: Phosphorous, Calcium) *why is the calcium so important? •Movement •Protection •Blood Cell Formation
  3. 3. Classification of BonesClassification of Bones Spongy Bone Compact BoneSpongy BoneSpongy Bone
  4. 4. Classification: Bone ShapesClassification: Bone Shapes Long Bones:Long Bones: Femur, Tibia, Fibula, Humerus, Radius and Ulna *What's wrong with this bone?
  5. 5. Classification: Bone ShapesClassification: Bone Shapes Short BonesShort Bones: Wrist Ex:Ex: Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate & Hamate Easy way of remembering this order? “Some Lovers Try Positions That They Cant Handle” (Get your minds out of the gutter)
  6. 6. Classification: Bone ShapesClassification: Bone Shapes Irregular bonesIrregular bones Vertebrae Pelvis Vertebrae
  7. 7. Classification: Bone ShapesClassification: Bone Shapes Flat BonesFlat Bones *Would the Shoulder bladeShoulder blade aka ScapulaScapula be considered a flat bone? Ribs and Sternum Skull Ribs and Sternum Skull Ribs and Sternum Skull Ribs and Sternum

  10. 10. Closer Look: Long BoneCloser Look: Long Bone EpiphysisEpiphysis: Cartilage covers both ends Contains Spongy bone DiaphysisDiaphysis (the shaft): Composed of mainly compact bone with a hollow cavity Medullary CavityMedullary Cavity: Stores fat and marrow that produces blood cells Yellow MarrowYellow Marrow: Fat storage Red MarrowRed Marrow: Produces Blood Cells stimulated by Erythropoietin (EPO)
  11. 11. Closer look: DevelopmentCloser look: Development Embryo:Embryo: Bone is mainly Hyaline cartilage Fetus:Fetus: Cartilage is replaced with Bone. Bone grows in lengths. Child:Child: Cartilage is mostly found on the proximal and distal ends. Bone grows in Width. EpiphysealEpiphyseal plateplate is still cartilage. What do you think happens to the Epiphyseal plateEpiphyseal plate as an ADULT?
  12. 12. FracturesFractures 1)The bone is broken, blood vessels are ruptured and a Hematoma (blood clot) forms 2) Fibrocartilage and spongy bone form with new blood vessels growing into the area
  13. 13. FracturesFractures 3) Bone starts to replace the Fibrocartilage and a Bony “Callus” is formed 4) Bone is “remodeled” due to stresses and form a strong patch
  14. 14. FracturesFractures Collar bone (clavicle) 3-8 weeks Shoulder blade (scapula) 6 weeks Ribs 4 weeks Upper arm (Humerus) 4-10 weeks Lower arm 6 weeks Wrist 4-12 weeks Fingers 4-6 weeks Pelvis 4 - 6 weeks Upper leg (femur) 12 weeks Knee (patella) 4-6 weeks Lower leg (tibia)10-24 weeks Ankle 6 weeks Foot3 - 12 weeks Toes3 weeks Bones and Healing timesBones and Healing times
  15. 15. Types of fracturesTypes of fractures Comminuted:Comminuted: The Bone breaks into many pieces *Seen in the elderly due to brittleness of bones*
  16. 16. Types of fracturesTypes of fractures Compression:Compression: Bone is CRUSHED
  17. 17. Types of fracturesTypes of fractures Depressed:Depressed: Broken Bone portion is pressed inward What does that LOOK like?
  18. 18. Types of fracturesTypes of fractures Impacted:Impacted: Broken bone ends are forced into one another
  19. 19. Types of fracturesTypes of fractures Spiral:Spiral: Bone is twisted excessively and a ragged break occurs I found some videos of this type of break but I didn’t want anyone vomiting class. Spiral:Spiral: Bone is twisted excessively and a ragged break occurs
