IMO, and I could be wrong, but the drive from Minn/St Paul, other than the Mall of America in Minneapolis, has nothing of interest until you get to the Badlands, Custer STate Park, Crazy HOrse, Mt Rushmore area. Deadwood SD for a day and night, I found to be of interest.
Sinoatrial node is located at the junction of the superior vena cava with the right atrium.
On the left an image at the level of the lower trachea just above the carina. To the left of the trachea 4L nodes. Notice that these 4L nodes are between the pulmonary trunk and the aorta, but are not located in the AP-window, because they lie medially to the ligamentum arteriosum.The node lateral to the pulmonary trunk is a station 5 node. 5.Subaortic nodes. Subaortic or aorto-pulmonary window nodes are lateral to the ligamentum arteriosum or the aorta or left pulmonary artery and proximal to the first branch of the left pulmonary artery and lie within the mediastinal pleural envelope.n 2009 a new Lung cancer lymph node map was proposed by the International Association for the Study of Lung Cancer (IASLC) in order to reconcile the differences between the Naruke and the MD-ATS maps and refine the definitions of the anatomic boundaries of each of the lymph node stations (2).
