Musculoskeletal system

  1. how many bones are there in the body
    206
  2. what are the 6 main functions of the Musculoskeletal system
    • movement 
    • protection
    • support 
    • mineral storage
    • blood cell production
    • energy storage
  3. what is the largest bone in the body
    femur
  4. what is the hollow space in bone called
    medullar
  5. what is the outside layer of the bone called
    intra osseous periostean
  6. name the 5 different types of bone
    • flat - sternum
    • sesamoid - patella
    • long - femur
    • short - wrist bone
    • irregular - vertebra
  7. label the diagram of the skull and the body bones
    see diagram
  8. list the vertebral column top to bottom and the number of bones
    • cervical - 7
    • thoracic - 12
    • lumbar - 5
    • sacral - 5
    • coccygeal - 4
  9. what are the bones in the thoracic cage called, number them.
    • ribs - 12 pairs
    • 7 true pairs
    • 3 false pairs
    • 2 floating
  10. what is the widest part of the femur called
    greater tronchanter
  11. what do joints allow
    movement and flexibility and attachment between bones
  12. what joint is not flexible
    fibrous
  13. what joint can bend slightly and has cartilage
    cartilaginous joint
  14. what is a key characteristic of the cartilaginous joint
    acts as a shock absorbent between bones
  15. what is a synovial joint
    a capsule joint which allows movement
  16. list the types of synovial joints and give examples of each
    • ball and socket - shoulder and hip
    • gliding - joints in the carpal bones
    • hinge - elbow
    • pivot - 1st and 2nd cervical vertebra
  17. what is a ligament
    tough fibrous tissue that binds bone to bone
  18. what is a tendon
    a fibrous tissue that fuses muscle to bone
  19. what are the main functions of the skeletal muscle
    • body movement
    • position stability
    • storage and movement of internal substances
    • generates heat
  20. how does the skeletal muscle create movement
    exerting a force on tendons pulling on bones to  create movement
  21. what is the origin
    the point of attachment of tendon that initiates the movement
  22. what is the insertion
    the point of attachment to the bone that is being moved
