1

Aorta relationship to espohagus

Anterior at first and then moves posterior as it descends

2

Direct aortic branches supply

Bronchi
Esophagus
Diaphragm
Body Wall

3

Top 1/3 - skeletal
Middle 1/3 - skeletal and smooth
Bottom 1/3 - smooth

4

Esophagus constriction points

Arch of aorta
Left main bronchus
Diaphragm opening

5

Vaugs nerves pass through which mediastinum?

Superior and posterior

6

Vagus nerve relationship to lung root

Posterior

7

Vagus nerve branches and how they move

Recurrent laryngeal
Left - loops around aortic arch
Right - loops around right subclavian

8

Types of fibers in vagus nerve

Pregang parasym to eosphageal, pulmonary, and cardiac plexi

9

Sympathetic fibers of cardiac and pulmonary plex are

Postganglionic

10

Sympathetic fibers of esophageal plexues are

Pre and postganglionic

11

How does vagus nerve pass through diaphragm?

With esophagus
R - posterior vagal trunk
L - anterior vagal trunk

12

Azygos system

Series of veins on dorsal body wall

13

What does azygos sytem drain?

Posterior thorax and ab walls

14

Veins that drain into azygos?

Posterior intercostal, esophageal, bronchial, and mediastinal

15

Where do azygos and hemiazygos veins originate?

Abdomend from veins that connect to IVC

16

Why is azygos system important?

Connects IVC with SVC of the heart for alternate routes of nevous return

17

Accessory hemiazygos vein

Drains superior left thoracic wall

18

Hemiazygos vein

Drains inferior left thoracic and abdominal wall

19

Azygos vein drains into

SVC

20

Cisterna chyli located

Anterior to L1/L2 vert

21

Thoracic duct empties into

Left subclavian and left internal jugular vein junction

22

Right lymphatic duct drains

Right upper ext, right side of head, right side of thorax

23

Branch of thoracic duct emptying the thorax

Left bronchomediastinal trunk

24

Brachipcephalic vein forms from joining of

Subclavian and jugular veins

25

Superficial vessels of thoracic wall and what they drain

Skin and superficial fascia (including mammary glands)
Axillary
Parasternal
INtercostal

26

Deep vessels of thoracic wall and waht they drain?

Diaphragmatic
Drain thoracic muscles, intercostal tissues, and diaphragm

27

Parietal nodes

Parasternal, intercostal, and diaphragmatic nodes

28

Visceral nodes of thorax drain

Heart, lungs, leura, thymus, and esophagus

29

Anterior mediastinal nodes location, what they drain, where they go

Superior mediastinum, anterior to great heart vessels
Drain the heart, pericardium, thymus, and others nearby
Drain into right and left bronchomediastinal trunks

30

Posterior mediastinal nodes location, what they drain, where they go

Posterior to pericardium by esophagus and aorta
Receive from esophagus, pericardium, and diaphragm
Drain to thoracic duct

31

Tracheobronchial nodes, what they drain, and where they g o

Surrounding structures
Right and left bronchomediastinal trunks
