Introduction to the Mediastinum Anatomy Flashcards
Where does the vagus nerve meet the heart
The vagus nerve passes across the ventral part of the aortic arch
What does the vagus nerve become
The vagus nerve becomes the rlaryngeal nerves
What is a landmark used to spot the vagus nerve
The ligamentum arteriosum
What does the azygos vein drain
It carries blood from the posterior chest and abdominal walls
What thoracic level is the carina
T4/T5
Where do the greater, lesser and least splanchnic nerves come off of the spine
Greater T5-9
Lesser T10-T11
Least T12
Asleep from 5-9
Hungover from 10-11
Somehow at lectures at 12
What does the thoracic duct drain
It is the main lymphatic vessel of the body
It does most of the body except the right side of the head and right limb
What might the thoracic duct look like in a dissection
A white thin nerve like tube posterior to the oesophagus
Where does the vagus nerve go through the diaphragm
It goes alongside the oesophagus at T10
What are the sites of narrowing that should be seen on a barium swallow
Aortic Arch
Left main bronchus
Left Atrium
Diaphragm
What damage might an aortic aneurysm cause
Injury/Damage to the recurrent laryngeal nerve as it presses on the nerve
Bronchial Arteries
3 Branches off the descending thoracic aorta; they supply oxygen to lung tissue, trachea and bronchi and do not participate in any gas exchange
