Q

How do you get three regions of the axillary artery?

A

with respect to the pectoralis minor muscle

17
Q

distal to the first rib and proximal to pectoralis minor describes what region?

A

Region I

18
Q

Deep to the pectoralis minor describes what region?

A

Region II

19
Q

Distal to pectoralis minor and ends at teres major muscle describes what region?

A

Region III

20
Q

How is the subclavian artery divided?

A

Into three regions with respect to the anterior scalene muscle

21
Q

What is the continuation of the axillary artery after reaching the inferior border of the teres major muscle?

A

Brachial artery

22
Q

What is the first branch off of the brachial artery?

A

deep brachial artery

23
Q

when does the deep brachial artery branch off of the brachial artery?

A

immediately distal to teres major muscle

24
Q

What does the deep brachial nerve travel with?

A

Radial nerve

25
Q

What branches does the deep brachial artery make?

A

Radial collateral artery and middle collateral artery

26
Q

After deep brachial artery, what is the next branch to come from the brachial artery?

A

Superior ulnar collateral artery

27
Q

What does the superior ulnar collateral artery travel with?

A

Ulnar nerve

28
Q

What is the next thing to branch off of the brachial artery after the superior ulnar collateral artery?

A

Inferior ulnar collateral artery

29
Q

Does the radial collateral artery travel anteriorly or posteriorly?

A

Anteriorly

30
Q

After making the inferior ulnar collateral branch, what does the brachial artery split into?

A

Ulnar artery and radial artery

31
Q

What is the first thing to branch off of the ulnar artery?

A

The anterior ulnar recurrent artery

32
Q

What branches off of the ulnar artery after the anterior ulnar recurrent artery?

A

posterior ulnar recurrent artery

33
Q

What branches off the ulnar artery after the posterior ulnar recurrent artery?

A

Common interosseous artery

34
Q

What is the most common site of venipuncture and why?

A

median cubital vein because of its superficial location and the protection of underlying deep structures by the bicipital aponeurosis
