Question

1. Mediastinal surface of right lung is related to all except:
(a) Right atrium
(b) Arch of aorta
(c) Arch of azygos vein
(d) Inferior vena cava​

Answer 1

Answer:

c is answer

Explanation:

The mediastinal surface of the right lung can be considered in terms of the lung root and surrounding surface characteristics. The root is considered to be approximately central upon the mediastinal surface, and the position of features is described with respect to this:

superiorly:

groove for azygous vein where it arches over the root of the right lung

more superiorly, groove for oesophagus vertically up to apex

anteriorly: groove for superior vena cava progressing vertically; groove is joined by groove for azygous vein posteriorly and grooves for subclavian and/or brachiocephalic vein superiorly

anteroinferiorly:

the cardiac impression: much shallower than the equivalent impression on the left lung

horizontal fissure runs obliquely and inferiorly across cardiac impression

a groove for the inferior vena cava running vertically down from the root

one end of the oblique fissure lies anterior to the groove for the inferior vena cava

inferiorly:

the pulmonary ligament

the lower part of a vertically-running groove for the oesophagus

posteriorly:

a groove for the oesophagus running vertically downwards immediately posterior to the lung root

more posteriorly in the superior third of the lung, the oblique fissur
