Q

what vetebral leve is the TTP?

A

T4

26
Q

what is the TTP

A

the transverse thorasic plane

27
Q

what is the significance of the Transverse thorasic plane

A

the TTP divides the Superior and inferior mediastinum and indicates the location for RAT PLANT

28
Q

What is RAT PLANT

A

Rib 2; Aortic arch (begining and end); Trachea biforcation; pulmonary trunk biforcation; ligamentum arteriorsum; Azygos Vein; Nerves (the Vegas nerve and the left and right recurent laryngeal nerve);Thoracic duct crossing over from right to left.

29
Q

What is the structure at the biforcation of the trachia?

A

corina

30
Q

What are the branches off of the corina?

A

the R and L primary bronchi

31
Q

where does the azygos vein enter the SVC

A

it arches above the right primary bronchus to enter the back of the SVC.

32
Q

What provides parasympathetic inervation to the cardiopulmonary plexus?

A

the right and left vegas nerve or CN ten that comes from the brain stem.

33
Q

What are the divisions of the mediastinum?

A

Superior and inferior, seperated by the TTP. The Inferior M.S. is divided into the Anterior/middle/posterior (divided by the borders of the heart). The Superior media stinum is divided into a Glandular plane, venous plane, arterial/nerve plane, visceral plane, and lymphatic plane.

34
Q

What are the structures of the inferior- posterior media stinum?

A

“D.A.T.E.S” Descending Aorta, Azygos veins, Thoracic Duct; Esophagus; Sympathetic trunk

35
Q

what is the derivitive of the word Mediastinum?

A

Midway

36
Q

What lies in the Anterior division of the inferior mediastinum?

A

the Thymus

37
Q

What is in the middle mediastinum

A

heart

38
Q

what is in the posterior mediastinum?

A

DATES

39
Q

How could a block in the Descending aorta lead to a high blood pressure in the intercostal arteries?

A

the descending aorta gives rise segmentally to the intercostal arteries.

40
Q

how could a RBC make a circumfrecal trip around the mediastinum?

A

the posterior and anterior intercostal arteries are connected usually through anastimosis.

41
Q

How could a swelling of the diaphram block off blood flow to the lower extremities?

A

the aorta travels through the diaphram at the T12 vetebral layer through the aortic hyatas.

42
Q

Describe the orientation of the Azygos system

A

The azygos vein goes up the right side of the vetebra colomn and over the right primary bronchi and into the back of the SVC; the Accessory Hemiazygos is on the left and drains the left posterior intercostal, and the Hemizygos is on the lower left and drains the lower lefter IC posterior veins.

43
Q

how could a anatomical narrowing of the hemizygos lead to problems in the abdominal?

A

the hemiazygos vein drains the abdominal region as well as the left posterior IC

44
Q

how much lymph per day in the thoracic duct

A

4 L

45
Q

you get punched in the diaphram, what is squashed first…the esophagus or the descending aorta?

A

the esophagus goes through the diaphram at the T10 level, and the aorta not until the T12.

46
Q

the diaphram contacts and swells at the T10 level, what structure are we concerned will get squished?

A

the Esophagus and the Vegas nerve that travels on the anterior and posterior of the esophagus.

47
Q

Oh no…an unknow infection just infected the celiac gangleon, will this possibly effect the parasympathetic?

A

YES, THE vegas nerve goes to the celiac gangleon on the way to synapse at the fore and midgut structures!.

48
Q

what is the eophageal plexus?

A

the tagle of vegas nerve around the esophagus.

49
Q

The same infection at the celiac gangleon will affect the synapse of what sympathetic?

A

the Greater splanchnic nerve (T5-T9 origin)

50
Q

what is the destiny of the post gangleonic neuronal cell bodies in the Sympathetic chain?

A

they go to the sweadt glands and the head neck and heart and lungs.

51
Q

Describe the path of a visceral sensory neuron from the heart:

A

from the heart along the sypmathetic nerve path back passing through the chain, through the white communicon, through the ventral ramus, trunk dorsal root and lateral horn!

52
Q

how could impinging on the internal nodal fiber lead to loss of sympathetic control of anything above T1

A

the sympathetics travel out the ventral root, to the gray matter communicon to the chain, up and down the nodal fibers to the right level (even above the T1 level) and then synapse and out the white matter comunicoon to the target.

53
Q

Where does the lesser splanchinic nerve arise?

A

T10-T11

54
Q

wherer does the least splanchnic nerve arise?

A

T12

55
Q

where do the splanchinic nerves synapse?

A

the pre-aortic gangleon.

56
Q

what are the planes of the superior mediastinum highlighted by Dr. Morten?

A

the Venous plane, the Arterial plane, and the Visceral plane (esophagus/trachea)

57
Q

there is a block int eh venous return just before the heart, but only the left side of the face, and the left side of the body seem to be affecte?! how

A

the block must be in the right brachiocephalic vein above the junction with the left brachiocephalic n.

58
Q

Describe the venous plane of the superior mediastinum

A

the SVC branches to the left and right brachiocephalic, which branch to the left and right internal jugular, and the left and right subclavian.

59
Q

where does the thoracic duct terminate

A

at the branch of the left brachiocephalic Vein (where it becomes the jugular and subclav.

60
Q

what section of the body is drained by the thoracic duct?

A

the whole body but the upper right quadrent.

61
Q

describe the arterial branches of the aortic arch

A

first is the brachiocephalic artery trunk that then will biforcate to the right subclavian artery and the right common corotid artery. Then the left common carotid artery, and then the left sublcavian artery both come directly off of the arotic arch

62
Q

what lies in the visceral plane of the superior mediastinum?

A

the trachea and the esophagus.
