  1. sternocleidomastoid
    • largest lateral neck muscle
    • palpable on side opposite of head turn
    • o - anterior surface of the sternum, superior surface of the medial end of the clavicle
    • ins - mastoid process of the temporal bone
    • inn - XI accessory nerve
    • f - head rotation
    • when head fixed, raises ribs - forced inhalation
    • (whip lash, problem with turning head)
  2. scalenes
    • o - transverse process of C3-6 anterior, C2-7 medial, C5-7 posterior
    • ins - ribs 1 and 2
    • f - raises ribs 1 and 2 - forced inhalation
  3. latissimus dorsi
    • o - spinous processes of T7-12, L1-5, S1-5, crest of the ilium, slips from ribs 10-12
    • ins - upper humerus
    • f - raises lower ribs - forced inhalation
    • compresses thorax - exhalation
  4. pectoral major
    characteristics
    • largest superficial muscle
    • broad origin along the sternum
    • funnels up : laterally to the arm
  5. pectoralis major
    • o - anterior surface of the sternum
    • costal cartilage of true ribs
    • sternal half of the clavicle
    • ins - humerus
    • f - raises ribs - forced inhalation
  6. pectoralis minor
    • located innediately behind the pectoralis major
    • o - body of ribs 3,4,5
    • ins - corocoid process of the scapula
    • f - raises upper ribs - forced inhalation
  7. subclavius
    • o - rib 1 and costal cartilage
    • ins - lower border of the clavicle
    • f - raises rib 1 - forced inhalation
  8. external obliques
    • largest and most superficial of the abdomen
    • o - digitations from ribs 4-12
    • c - down and medially
    • ins - iliac crest, abdominal aponeurosis
    • f - compresses viscera - exhalation (internal organs)
  9. internal obliques
    • lies below ext. oblique
    • o - iliac crest
    • c - up and medially
    • ins - abdominal aponeurosis, ribs 8-12
    • function - compresses viscera - exhalation
  10. transversus abdominis
    • o - iliac crest, ribs 6-12
    • c - laterally
    • ins - abdominal aponeurosis
    • f - compresses viscera - exhalation
  11. rectus abdominis
    • o - pubc crest, pubic symphysis
    • c - vertically
    • ins - ribs 5,6,7, xiphoid process
    • f - lowers ribs, compresses viscera - exhalation
  12. muscles of quiet inhalation
    • diaphragm
    • external intercostals
    • internal intercostals
  13. musles of forced inhalation 8
    • levatores costarium
    • serratus pposterior superior
    • sternockimastoid
    • scalenes
    • latissimus dorsi
    • pectoralis major
    • pectoralis minor
    • subclarious
  14. muscles of exhalation 8
    • internal intercostals
    • subcostals
    • transverse thoracics
    • external oblique
    • internal oblique
    • transverse abdominis
    • rectus abdominis
    • serratus posterior inferior
  15. lung volumes
    • tidal volume - what we inhale and exhale (10% of TLC)
    • inspiratory reserve volume - volume of air inhaled after inspiration (taking deep breath) (40% of TLC)
    • expiratory reserve volume - exhaling as much as you can forcibly after passive exhalation (30% of TLC)
    • residual volume - volume of air remaining in lungs after macimum ahalation (20% of TLC) this will always be there because the lungs will collapse without it
  16. lung capacities
    combination of volumes measured in milliliters or cubic centimeteres
  17. 4 lung capacities
    • vital capacity - 80% TV + ERV + IRV
    • inspiratory capacity - 50% IRV + TV
    • functional residual capacity - 50% RV + ERV
    • total lung capacity - IRV + FRC + TV
