  1. what are the types of vertebrae
    • cervical-7
    • thoracic-12
    • lumbar-5
    • sacral-5
    • coccyx-3/4 fused
  2. thorax
    • skeletal thorax (aka ribcage)
    •     -thoracic vertebrae
    •     -ribs
    •     -sternum
    • houses viscera (aka internal organs)
    • protects and supports respiratory function
  3. what are the three types of ribs?
    • true ribs-1-7
    •     -connect to the sternum via costal cartilages
    • false ribs-8-10
    •     -connect to the 7th rib via the costal arch
    • floating ribs-11-12
    •     -do not attach to the front of the throax
  4. name the parts of the sternum:
    • manubrium
    • body (corpus)
    • xiphoid process

    • function:
    •     -attachment for muscles and cartilages of the thorax
  5. what are the two parts of the pulmonary system

    • conducting airways
    •     -larynx
    •     -trachea
    •     -bronchi
    •     -alveoli
  6. describe the trachea
    • semi rigid tube
    • 16-20 c shaped cartilage
    • extends from C6 to T4or5
    • posterior membranous wall is the esophagus
  7. what are the two types of pleura?
    • visceral pleura-closest to the visceral organs
    • parietal pluera-further from the visceral organs
  8. explain pleural space
    • space between the visceral and parietal pleura 
    • pressure is negative
  9. what do the muscles of respiration work on in order to manipulate respiration?
    they work on the throax and abdomen causing the amount of air in the lungs (volume) to change
  10. how are the lungs attached and what does this help with?
    since the lungs are attached to the thorax via pleural pressure, forces exerted on the thorax will move the lungs
  11. diaphragm
    it is the main muscle of .......
  12. diaphragm
    • central tendon
    • xiphoid process of sternum
    • ribs (7-12) and their costal cartilages
    • lumbar vertebrae (1-3)
  13. diaphragm innervation
    • motor - phrenic nerve
    •     -composed of fibers from c3-5

    • sensory
    •     -phrenic nerve c3-5 centrally
    •     -intercostal nerves t5-11 peripherally
    •     -subcostal nerve t12 peripherally
  14. describe external intercostal muscles
    • origin: lower edge of one rib
    • insertion: upper edge of the rib immediately below
  15. describe Internal Intercostal Muscles
    •Origin: lower border of one rib

    •Insertion: upper border of the rib immediately below
  16. Internal and External Intercostals: Innervation

    –Intercostal nerves (T1-T11)

    •Spinal nerves at each vertebral level innervate the intercostal muscle at that vertebral level.
  17. Bony Pelvis (Hip Bones)
    •Ilium bone: 

    –Iliac crest

    •Ischium bone

    •Pubis bone:

    –Pubic symphysis

  18. Rectus Sheath
    •Rectus sheath: fibrous sheath formed by aponeuroses of abdominal muscles.
  19. Linea Alba
    •Linea alba: where the anterior and posterior portions of the sheath intermingle at the center of the abdomen.
  20. Rectus Abdominus attachments

    –Pubic symphysis and pubis bone

    –Xiphoid process

    –Costal cartilages of ribs 5-7

    •Compresses abdominal viscera.

    –Accessory muscle of exhalation
  21. External Oblique attachments

    –External surfaces of ribs 5-12

    –Linea alba

    –Pubis bone

    –Anterior portion of iliac crest

    •Compresses abdominal viscera.

    –Accessory muscle of inhalation
  22. Internal Oblique

    –Anterior portion of iliac crest

    –Thoracolumbar fascia (sheath of connective tissue on lower portion of the back)

    –Inferior borders of ribs 10-12

    –Linea alba, Pubis bone

    •Compresses abdominal viscera.

    –Accessory muscle of
  23. Transverse Abdominus

    –Internal surfaces of ribs 7-12 (costal cartilages)

    –Thoracolumbar fascia, Iliac crest

    –Linea alba, Aponeurosis of internal oblique

    –Pubic crest, Pubis bone

    •Compresses abdominal viscera.

    –Accessory muscle of ___________.
