Flashcards in Block 2 Mediastinum Deck (25):
1

two subdivisions of mediastinum

superior, inferior

2

inferior portion of mediastinum is subdivided into blank

anterior, middle, posterior

3

lymph nodes in the mediastinum should be blank and not really noticeable in cadavers

tiny

4

thymus is located in which part of mediastinum

anterior as well as superior/inferior

5

arteries in the anterior mediastinum

internal thoracics

6

two terminal branches of internal thoracic artery

musculophrenic, superior epigastric artery

7

branch of internal thoracic artery that supplies intercostal spaces

anterior intercostal artery

8

branch of internal thoracic that supplies phrenic nerve

pericardiophrenic artery

9

vena cava are on this side of vertebral column

right

10

two branches of superior vena cava

right/left brachiocephalic veins

11

arterial strucutres are on blank side of vertebral column

left

12

three branches off arch of aorta

brachiocephalic, left common carotid, left subclavian

13

only the blank nerve is in the superior mediastinum

left recurrent laryngeal

14

obstruction of svc leading to fluid accumulation and edemai in the head, neck , and upper limbs

superior vena cava syndrome

15

when left vertebral artery arises from the aortic arch, it arises between the blank and blank arteries

left common carotid, left subclavian arteries

16

descending aorta passes through the blank mediastinum

posterior

17

trachea bifurcates into right and left primary bronchi at blank

carina (beneath angle of louis)

18

primary bronchi are located in blank mediastinum

middle

19

thoracic duct drains lymph from the entire body except from here

right side of head, neck, upper right extremity, right side of thorax

20

this drains right side of head, neck, upper right extremity, right side of thorax

lymphatic duct

21

left vagus nerve gives rise to this nerve

recurrent laryngeal nerve

22

contents of posterior mediastinum

esophagus and vagal plexus, descending aorta, thoracic duct, azygos veins, splanchnic nerves

23

greater splanchnic nerve has these fibers

visceral afferent, visceral efferent

24

azygos vein is on the blank and drains the intercostal spaces on this side

right

25

hemiazygos vein is on the blank and drains the intercostal spaces on this side

left
