The Skeletal System

The skeletal system is essential for human body structure and function, providing support for locomotion and protecting vital organs. Major organs of the skeletal system include long bones, which produce red blood cells. The system is divided into two main categories, incorporating minerals like calcium, magnesium, and phosphorus. Different types of bones exist, such as flat, irregular, and long bones, each serving unique purposes. The skeletal system also features various joints and cartilage types, playing critical roles in mobility. Common disorders include osteoporosis and arthritis, affecting bone health.

  1. The Skeletal System Sabrina Pralle, EmreTaner, Simone Frandsen and Breanna McGuire

  2. The Basics • Long bones produce red blood cells • Provides support and structure for locomotion • Protection of major organs • Bones are the major organs of the skeletal system • There are two main divisions on the skeletal system

  3. Minerals present • Calcium • Potassium • Manganese • Magnesium • Silica • Iron • Zinc • Selenium • Boron • Phosphorus • Sulfur • Chromium

  4. Types of Bone • Flat • Thin and relatively flat but may be curved • EX: Sternum • Irregular • Is not regular in shaped • EX: Vertebra • Long • Longer than they are wide • EX: Femur • Short • Almost as wide as they are long • EX: Carpal bones http://www.bbc.co.uk/science/humanbody/body/interactives/3djigsaw_02/index.shtml?skeleton

  5. Different Layers of the Bone • Epiphyses • Epiphyseal Plate/Epiphyseal line • Diaphysis • Red marrow • Articular cartilage • Periosteum • Medullary cavity • Yellow marrow • Endosteum • Osteoblasts and osteoclasts

  6. Types of Joints • Hinge • Pivot • Saddle • Ball-and-socket • Condyloid • Planar (gliding)

  7. Types of Cartilage • Hyaline • Fibrocartilage • Elastic

  8. Functions of Cartilage • Cushions joints • Flexibility and the capacity to bend • Resilience and give

  9. Disorders, diseases, deficiencies • Osteoporosis • Arthritis • Polydactyl • Calcium deposits/ deficiencies • Bone spurs • Osteogenesisimperfecta • Bone cancer • Bursitis • Scoliosis • Fractures
