Q

Transversis thoracis

A
  • radiate out from breast bone
  • innvervation = related intercostal nerves
  • fn = depress costal cartilages, exhaling
24
Q

thoracic arterial system

A
  • Aorta = brachiocephalic trunk, common int. carotid, subclavian + anterior/posterior intercostal
25
Subclavian
off subclavian = 2 lateral internal thoracic arteries -> bifurcate at rib 7 to terminal musculophrenic and superior epigastric art
26
Anterior + posterior intercostal
- anterior intercostal arts branch off internal thoracic arteries at each rib. - Posterior intercostal off aorta -> costal groove -> form anastamotic connection (still bleed when cut) at midaxillary line
27
Azygos Vein
- right side = Ant + post intercostal vein -> azygos vein -> brachiocephalic vein - left side = accessory hemiazygos (ribs 1-9) + hemiazygos (ribs 10-12) -> azygos system - draining R/L thoracic cages
28
Thorax Lymphatics
- post thorax lymph -> intercostal nodes (in back - infections in back go to these nodes) - Anterior -> parasternal nodes - all return to braciocephalic nodes -> thoracic duct -> venous system
29
Thorax Wall Inntervation
all autonomic Nipple level = T4 Xiphoid Process = T6 Umbilical/ belly button = T10
30
Intercostal nerve/space
- ventral rami, wrap around - over sternum w/ant cutaneous branch - space = vein, artery, nerve (VAN) - chest tube - decompress pressure, can cause damage
31
Manubriotsternal + xiphisternal joints
symphysis
32
Pleural Cavities
- R/L pleural cavity, pericardial cavity | - pericardial in mediastinum
33
Diff Parts of Pleura
Costa (ribs) + mediastinal (heart) + | diaphragmatic + cervical pleura = where lungs sit
34
Pleural recess
- space for lung to expand | - space for infection/fluid buildup
35
costodiaphragmatic recess
- space for lungs to go down on inhalation – # 1 location for fluid accumulation
36
Lungs
- Right lung = 3 lobes; left lung = 2 lobes - mediastinal to lungs = pul art superior to pul veins - Pleural mem – hilum – surrounds lung roof
37
Left Lung
- superior + inferior lobes separated by oblique fissure (rib 6) - Cardiac notch = space for heart - Lingula – tongue like projection - depressions on mediastinal surface
38
Left Lung Vasculature
- aorta + aortic arch | - left subclavian art + braciocephalic vein at lung apex (above superior thoracic aperature, tumor site)
39
Right Lung
- 3 lobes = superior, middle and inferior - horizontal fissure (superior from middle at 4th intercostal) - oblique (middle from inferior at 5th intercostal space, rib 6)
40
Right Lung Vasculature
- inferior + superior vena cava - Azygos system - esophagus - subclavian art + vein
41
Trachea
- CV 6 -> TV 4, bifurcates to R/L bronchus
42
Bronchi
- R bronchus = more vertical, gets more foreign bodies (least resistance) - L bronchus - shallow, longer, for heart - main bronchus -> lobar/secondary bronchi (supplies lobes -> segmental/tertiary bronchi (supplies bronchopulmonary segments)
43
Bronchoscopy
- stick scope down pt’s windpipe - Carina = bifurcation of trachea - 3/2 secondary -> keep branching off and get smaller
44
Bronchopulmonary Segments
- Segmental bronchus - Pul art branch - Pul venous drainage – pass intersegmentally btwn/around margins of segments
45
Pulmonary Arteries
- Originate from pul trunk (right ventricle) - Trunk bifurcates ~ T4-T5 (anterior/inferior to bronchus) - Deoxygenated blood
46
Right Pulmonary Artery
- longer than left - posterior to ascending aorta, superior vena cava and upper right pulmonary vein - anterior to right main bronchus
47
Left Pulmonary Artery
- shorter than right - anterior to descending aorta and left main bronchus - posterior to superiorpulmonary vein
48
Pulmonary Veins
- each side contain two pulmonary veins - Superior + Inferior pulmonary vein - Carry oxygenated blood to left atrium
49
Pulmonary Vasculature
- Bronchi + pulmonary arteries pair/branch in unison. | - Pulmonary veins from pul caps, drain toward and course in septa btwn adjacent segments.
50
Bronchial Arteries + Veins
- thoracic aorta -> post surface of bronchus | - Veins drain to pul veins/left atrium + azygos system
51
R/L bronchial artery
- R Bronchial art - from 3rd posterior intercostal artery | - L Bronchial art - from aorta
52
Pulmonary Innervation
- GVA/GVE via anterior and (mainly) post pul plexus - Vagus nerve = parasymp – constrict bronchioles - Symp (T4) chain = symp – dilate bronchioles - pul plexus accompany bronchi + arts in lung.
53
Lymph Drainage
- Lungs drain to tracheobronchial nodes -> bronchomediastinal trunks - Right lung + L inferior lung lymph to inferior tracheo-bronchial (carinal nodes), ascend up right side - L superior of left lung – goes bronchopulmonary (hilar nodes) and goes up left side
54
Lymph nodes
- Pulmonary = lobar bronchi - Bronchopul = hilum of lung (drain from superficial lymphatic plexus) - Inf. Tracheobronchial (Carinal nodes) - Superior tracheobronchial - Tracheal
55
Lung Sounds
- Apex of lung – above clavicle - Superior lobe – 3rd intercostal space on either side - Right side – middle lobe – 5th intercostal space, close to sternum - Inferior lobe – more axillary, 7th intercostal space
56
things you don't want in pleural space
- Pneumo (air) – from penetrative trauma, pneumothorax - Hydro (water) – due to infection - Hemo (blood) – infection, intenral trama
57
Thoracocentesis
- withdraw fluid – syringe on superior border of lower rib, needle at upward angle - aim for middle 7th intercostal space mid axillary (make sure in thoracic cavity, also go as low as possible because of gravity + fluid.
