5. The thoracic duct reaches the left side of the esophagus in its passage upwards from the abdomen

6. Ligamentum arteriosum

7. Left recurrent laryngeal nerve recurves below the ligamentum arteriosum.

8. superficial part of cardiac plexus

Answer 2

Arch of aorta ends

Descending aorta begins

The body of the vertebrae

Arch of aorta begins

The Burification of the pulmonary track

The level of rib where it attached to the sternum through Costal cartilage.

The Burification of the trachea

Superior and inferior mediastinum are demarcated

Answer 3

At the sternal angle, also known as the Angle of Louis, several important anatomical landmarks and events occur. The second rib articulates with the sternum at this point, making it a useful landmark for counting ribs. The trachea bifurcates into the left and right main bronchi at the level of the sternal angle. Additionally, the aortic arch transitions into the descending aorta at this anatomical landmark.

Answer 4

Oh, dude, the sternal angle is where all the cool stuff happens. You've got the articulation of the manubrium and the body of the sternum, the second rib attaches there, and the trachea bifurcates into the right and left main bronchi. It's like the party central for your upper chest anatomy.
