Flashcards in Internal thorax Deck (43):
1

Source of sym innervation

T1-L2

2

Source of parasymp innervation

brain stem and S2,3,4

3

contents of middle mediatinum

pericardium, heart, origins of great vessels

4

borders of middle mediastinum

ant, post, sup

5

contents of ant mediastinum

internal thoracic vessels + thymus

6

contents of sup mediastinum

esoph, trach, aortic arch, brachiocehpalic veins, SVC, brach. trunk (art) left common carotid + left subclavian, phrenic, vagus, L recurrent laryngeal

7

order of sup mediastinum vessels

veins, arteries, wind, water - ant to post

8

course of vagus nerve (X)

runs down along esophagus

9

contents of post mediastinum

symp trunk, throracic duct, azygous(es), dec aorta, esoph, primary bronchi

10

4 portions of parietal lung pleura and their innervation

cupola - supraclavicular
mediastinal - phrenic
costal - intercostals
diaphragmatic - intercostal (ext) and phrenic (int)

11

level of tracheal bifurcation

T4/5

12

vessels that loop over trach

L - aorta
R - azygous

13

bronchi branches

primary (main)>secondary (lobar)> tertiary (segmental > intrapulmonary

14

surfaces of lung

apex, base, costal, mediastinal

15

pulmonary ligament

fold at the inferior reflection of root of lung

16

level of pulm artery branches

T4/5

17

Blood supply to lung

bronciole arts (aorta+intercostals) and veins (azygous +hemiazygous)

18

Lymph drainage path from deep to superficial

pulmonary nodes>bronchopulmonary nodes>tracheopulmonary nodes>bronchiomediastinal lymph trunks

19

Lung innervations

from symp trunk and vagus via pulmonary plexus

20

air or blood in pleaura

pneumothorax and hemothorax

21

suface reflection - pleural borders

R - sternocalvicular joint to sternal angle>down to rib 6>lateral to rib 8 in midclavicular line>to 10 in midaxiallary>12 in back
L - sternocalvicular joint to sternal angle>down to rib 4> laternal to edge of sternum>down to rib 6>lateral to rib 8 in midclavicular line>to 10 in midaxiallary>12 in bacl

22

surface reflection - lung borders

R - neck of first rib>down mid sternum to rib 6> along 6 to midclavicular>8 in mid axillary>10th in back (2 below plearal border)
L - neck of first rib, down mid-sternum to 4, along 4 to midclavicular, then down to 6 in mid-clavicular>to 8 in midaxiallary>10 in back

23

two lung recesses

costodiaphragmatic, costomediastinal

24

3 methods of chest expansion

vertical - diaphram down
anterior post - intercostal muscles contract
transverse - intercostals

25

point of reflection of serous pericardium

outflow of great vessels -transverse sinus
inflow vessels - oblique sinus

26

cardiac tamponade

too much pressure in pericardial cavity

27

conection b/w aorta and pulm trunk

ligametum arteriosum - was ductus arteriosus

28

difference between somatic and autonomic signals

somatic - single nerve
autonomic - double nerve w synapse

29

location autonomic synapse

peripheral ganglion

30

location of preganglionic cell neurons

grey matter in lateral horn of spinal cord

31

anatomic diff between symp and para symp

symp - in T1-L2, post gang in symp chain
para - in cranial or S, post gang close to organ

32

location of prevertebral plexus

anterior to vert column all down thorax and abdo

33

Grey vs white rami communicantes

grey - postganglionic fibers from sym ganglia
white - preganglionc fibers from ant primary rami

34

names of syp splanchnic nerves

greater, lesser, least, lumbar, sacral

35

path of symp innervation to abdo organs

lateral horn>through ganglion (no synapse)>down splanchnic nerve>to prevertebral plexus (synapse)> to organ

36

para innervation as far as SMA

vagus nerve

37

types of afferents in para vs symp fibers

para - special senses (blood pres)
symp - referred to body surface

38

path of throacic duct

cysterna chyli>up along vert passing R to L>into brachiocephalic

39

branches of the aorta

R brachiocephalic to R subclavian and carotid
L carotid and subclavian
intercostals
esophageal branches
bronchial arteries

40

level esophagus starts

C6

41

potential blocks of esophagus

C6 - cricoid cartelege
T4/5 by aortic arch
T10 by diaphragm

42

blood supply and drainage of esophag

- broncial, esphageal, L gastic art
- azygous and hemiazygous veins, gastic veins

43

3 drainages of esoph lymph

upper- internal jugular node
middle - mediastinal nodes
lower- celaic nodes
