What artery runs through the axilla?
the axillary artery
The axillary artery is a continuation of which artery?
the subclavian
Which part of the axillary artery is behind the pec minor and what arteries branch from it?
2nd Part
Branches: Lateral; Thoracic and Thoracoacromial
What branches come directly off part 3 of the Axillary Artery?
Subscapular Artery
Anterior and Posterior Circumflex Humeral

Describe the Brachial Plexus:
Roots: C5-T1 Vent Rami Trunks: Superior, Middle, Inferior Divisions: Anterior Poster (6) Chords: Lateral, Posterior, Medial Branches: MusC., Axillary, Median, Radial, Ulnar (MMU from Medial and Lateral Chords)
Which vein borders the pec major and deltoid and what is the space in which it runs?

Superior Trunk
What ligament transverses the scapular notch?
Superior Transverse Ligament
What neurovascular structures run below and above the superior transverse ligament of the scapular notch?
Under - Suprascapular Nerve
Above - Suprascapular artery
The subclavian nerve comes from where?
