The flashcards below were created by user shanamd2011 on FreezingBlue Flashcards. What would you like to do?


  1. respiration
    gas exchanging system
  2. inspiration
    bringing oxygen to the cells
  3. expiration
    elimination of waste by breathing out
  4. respiration takes place in
    • alveoli
    • minute air sacs in lungs
  5. respiratory skeleton
    • the spine
    • the girdles
    • the ribs
    • the sternum
  6. bones of the spine / vertebral column
    • cervical certebrae 7 (C1 - C7)
    • Thoracic Vertebrae 12 (T1 – T12)
    • Lumbar Vertebrae 5 (L1 – L5)
    • Sacral Vertebrae 5 become 1 (sacrum)
    • Coccygeal Vertebrae 3-4 become 1 (coccyx)
    • 32 - 33 segments of bone
  7. vertebral anatomy (landmarks)
    • body
    • pedicles
    • laminae
    • spinous process
    • transverse processes
    • vertebral foramen
    • facets (Articular and Costal)
    • variations
  8. body
    corpus / rounded projection
  9. pedicles
    projections off the body
  10. laminae
    found off of the pedicles
  11. spinous process
    downward projection on posterior end
  12. transverse process
    lateral projections off the side
  13. vertebral foramen
    posterior to corpus; hole through which spinal cord passes
  14. facets
    where 2 vertebrae will meet
  15. articular facets
    • off pedicle
    • superior and inferior
  16. costal facets
    • articulate with ribs
    • inferior - found off of body
    • superior - found off of body
    • tranvserve - found on transverse process
  17. variations of vertebreal anatomy
    C1 atlas and C2 axis
  18. the C2 axis has the
    • dens
    • odontal process
    • allows for rotation of C1
    • only found on C2
  19. girdles attachments
    • upper extremities attached to vertebral column by pectoral girdle
    • lower extremities attached through pelvic girdle
  20. girdle landmarks
    • shoulder - pectoral
    • figure - scapula
    • clavicle - collarbone
    • pelvic
  21. scapula landmarks
    • acromion process - attaches to clavicle
    • coracoid process - other rocess off scapula
  22. pelvic landmarks
    • Ilium - largest upper bone; attaches to sacrum
    • Ischium - lowest part
    • Pubis - comes together at the pubis symphysis
  23. bones of the ribs
    • true 7 - connect directly to the sternum
    • false 3 - connect to the ternum via rib 7
    • floating 2 - do not connect to the sternum
  24. landmarks of the ribs
    • head - articulates with the spinal column
    • neck - extends from head
    • angle - point at which rib curves
    • shaft/body/corpus - major point of rib
    • costal cartilage - attaches the ribs to the sternum
  25. sternum portions
    • manubrium - where clavicles articulate; R1 attaches
    • body - attached via costal cartilage to R1 through R7
    • Xiphoid Process / Ensiform - landmark for CPR
