What muscle determines the regions for the Subclavian Artery?
The Anterior Scalene
What are the three branches of Region 1 of the Subclavian Artery?
Vertebral Artery
Internal Thoracic Artery
Thyrocervical Trunk
What are the branches of the Thyrocervical Trunk?
Inferior Thyroid Artery
Suprascapular Artery
Transverse Cervical Artery
What is the only branch in Region 2 of the Subclavian Artery?
What does it give rise to?
Costocervical Trunk
Deep Cervical Artery (supplies Muscles of the Deep Neck)
What is the only branch in Region 3 of the Subclavian Artery?
Dorsal Scapular Artery
(Supplies Rhomboids and Levator Scapulae)
What defines the transition between the Subclavian and Axillary Arteries?
The First Rib
What is the only (and wimpy) branch of Region 1 of the Axillary Artery?
The Superior Thoracic
Despite its name, it’s pretty tiny and often not present

What causes pain and loss of sensation in Axillary Artery Aneurysm?
Compression of the Brachial Plexus
If you want to cut off blood supply to the Upper Extremity, where can you not put a ligature due to the Scapular Anastomosis?
Between the Thyrocervical Trunk and the Subscapular Artery
The blood can flow around the scapula and feed into the Brachial Artery from there.
The Brachial Artery makes four Collateral Arteries for the Elbow Anastomosis, which two come from the Deep Brachial branch?
Radial Collateral Artery
Middle Collateral Artery

Superior Ulnar Collateral Artery
Inferior Ulnar Collateral Artery
What two major Arteries make the Recurrent Arteries of the Elbow Anastomosis?
Ulnar A. (Makes 3)
Radial A. (Makes 1)
What are the branches of the Ulnar Artery that help form the Elbow Anastomosis?
Anterior Ulnar Recurrent Artery
Posterior Ulnar Recurrent Artery
Interosseous Recurrent Artery
What branch of the Radial Artery helps form the Elbow Anastomosis?
Radial Recurrent Artery
What Artery Anastomoses with the Middle Collateral Artery?
Interosseous Recurrent Artery
(SIMR over PAIR)
What two minor Arteries feed into the Dorsal Carpal Arches?
The Anterior and Posterior Interosseous Arteries
What major Artery of the Hand is responsible for the Superficial Palmar Arterial Arch?
The Ulnar Artery
What major Artery of the Hand is responsible for the Deep Palmar Arterial Arch
