Anatomy - Major Branches of the Subclavian Artery [Arteries of The Arm]

This video tutorial explains the pathway of the right subclavian artery, detailing its branches into the axillary, brachial, radial, and ulnar arteries, and their roles in supplying blood to the arm and hand. It highlights the equivalence of the left side's arterial system and previews the next video, which will cover the descending aorta and abdominal arteries.

What is the main difference between the right and left subclavian arteries?

• The right subclavian artery comes directly off the aortic arch.

• The left subclavian artery supplies the right arm.

• The right subclavian artery does not come directly off the aortic arch.

• The left subclavian artery is longer than the right.

Which artery does the right subclavian artery branch into above the armpit?

• Right axillary artery

• Right radial artery

• Right ulnar artery

• Right digital artery

What are the two major arteries that the right brachial artery diverges into?

• Right axillary and right radial arteries

• Right radial and right ulnar arteries

• Right brachial and right axillary arteries

• Right ulnar and right digital arteries

In anatomical position, which artery is lateral in the forearm?

• Right ulnar artery

• Right radial artery

• Right axillary artery

• Right brachial artery

What are the two vessel systems formed by the right radial and ulnar arteries?

• Right digital arch and right radial arch

• Right brachial arch and right axillary arch

• Right ulnar arch and right axillary arch

• Right deep palmar arch and right superficial palmar arch

Where is the superficial palmar arch located?

• On the back of the hand

• On the side of the hand where the palm is

• In the forearm

• Above the elbow

What do the right digital arteries primarily supply?
