Neurovasculature of the Upper Limb

Question 1

The subclavian artery arises from where?

Answer 1

Right side: right brachiocephalic artery

Left side: aorta

Question 2

What passes through the root of the neck?

Answer 2

The root of the neck contains the brachiocephalic trunk and the subclavian arteries, as well as the external and anterior jugular veins and the subclavian vein, and the vagus nerve, phrenic nerves and the sympathetic trunks.

Question 3

Where is the root of the neck?

Answer 3

The root of the neck is the area immediately superior to the superior thoracic aperture and axillary inlets and is bounded by the manubrium, clavicles, and T1 vertebra. The root of the neck contains structures that pass between the neck, thorax, and upper limb.

Question 4

The subclavian becomes which artery?

Answer 4

Axillary artery

Question 5

The subclavian becomes the next artery after passing over which structure?

Answer 5

First rib

Question 6

The axillary artery becomes which artery next?

Answer 6

Brachial artery

Question 7

When does the axillary artery become the next artery?

Answer 7

As it passes through the axillary region, as it passes the inferior border of the teres major muscle.

Question 8

The region where axillary artery becomes the next artery is significant in the venous blood flow. Why?

Answer 8

The axillary artery passes through the axillary region to become the brachial artery as it passes the inferior border of the teres major muscle. This is the same place where basilic and “brachial” veins form axillary vein.
