trachea extends fromlarynx to bronchi
2 portions of tracheacervical and thoracic
trachea divides at sternal angle forming the main bronchi
main bronchi divide intolobar (seccondary) bronchi
how many lobar bronchi for right lung3
what are the lobar bronchi for right lungsuperior, middle, inferior
how many lobar bronchi for left lung2
what are lobar bronchi for left lungsuperior, inferior
lobar bronchi divide intotertiary (segmental) bronchi

what are the tertiary bronchi segmented forbronchopulmonary segments
tertiary bronchi divide intoterminal bronchioles
how many generations of terminal bronchioles20-25
what is the chain of gas exchangerespiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
memorize

Question Answer
lungs are made ofmasses non-muscular tissue
what is mediastinumspace between lungs where heart is
what is the flexibility of the lungshighly elastic
which lung has cardiac notchleft
which lung is bigger and shorter to accomodate liverright
significance of cardiac notchaccommodate the pericardium
what divides the right lung lobeshorizontal and oblique fissures
what divides left lung lobesoblique fissures
what are both lungs divided intobronchopulmonary segments
memorize

how are membranes attacheda pleural space
memorize

Section 9

Question Answer
name for strong central tendonaponeurosis
diaphragm openingsaortic hiatus, esophageal hiatus, vena cava foramen
placement of diaphragmseparates thorax from abdomen
3 groups of muscle fiberscostal, sternal, lumbar
origin of costalinferior and inner surfaces of costal cartilages
origin of sternalinner inferior surface of the xiphoid process
origin of lumbarupper lumbar vertebrae, medial and lateral arcuate ligaments
insertions for the costal, sternal, and lumbarcentral tendon
actions of costal, sternal, and lumbarccontraction, pulls central tendon down, increases vertical and anterolateral dimensions of thorax
innervations of costal, sternal, and lumbarphrenic nerves originating from cervical spinal nerves (C3-C5)
memorize

Section 10

Question Answer

origin of external intercostalsinferior surface of the superior rib
insertion of external intercostalssuperior surface of the rib below
action of external intercostals and interchondral internal intercostalsexpand rib cage, stiffen chest wall
innervations of external intercostals and interchondral internal intercostalsintercostal nerves (T1-T11)
origin of interchondral portion of internal intercostalsinferior surface of rib spaces from the costochondral junction to the sternum
insertion of intercchondral internal intercostalssuperior surface of the rib below
memorize

Section 11

Question Answer
expiratory musclesinterosseous portion of internal intercostals, rectus abdominis, external oblique, transversus abdominus, transverse thoracis, latissimus dorsi
origin of interosseous internal intercostalsinner superior surface of the rib below
origin of rectus abdominispubic symphysis and pubic crest
origin of external obliqueexternal surfaces of the eight lowest ribs
origin of the internal obliquiliac crest, inguinal ligaments, thoracolumbar fascia
origin of transversus abdominusiliac crest, inguinal ligaments, thoracolumbar fascia, inner surface of cartilages of the lower 6 ribs
origin of the transverse thoracisinternal surface of the rib cage from the sternum and costal cartilages
origin of the latissimus dorsispinous process of the lower 6 thoracic vertebrae, thoracolumbar fascia, iliac crest, lower 3-4 ribs
insertion of interosseous internal intercostalsinner inferior surace of rib above
insertion of rectus abdominuscostal cartilages ribs 5-7 and xiphoid process of sternum
insertion of external obliqueiliac crest, inguinal ligament, aponeurosis of the external oblique
insertion of internal obliquecostal cartilages of the lowest 3-4 ribs, aponeurosis of the internal oblique
insertion of transversus abdominisaponeurosis of the transversus abdominus
insertion of transverse thoracisinternal surface of costal cartilages and adjacent portions of ribs 2-6
insertion of latissimus dorsianterior superior surface of the humerus
action of interosseous internal intercostalspull ribs down, stiffen chest wall
