Internal thoracic artery
What is the axillary artery? (161)
The fifth and last branch off the subclavian artery; main artery in the forelimb
What is the lateral thoracic artery? (161)
First branch from the axillary artery
Where does the lateral thoracic artery run? (161)
From the axillary artery to the chest wall
What is the subscapular artery? (162)
Second branch off the axillary artery; supplies the shoulder
What is the thoracodorsal artery? (161)
Branch from the subscapular artery
How does the axillary artery terminate? (161)
It branches into the subscapular and brachial arteries
Where does the thoracodorsal artery travel? (161)
Runs caudally; supplies teres major and lattissmus dorsi
What is the brachial artery? (166)
Continuation of the axillary artery
Where does the brachial artery travel? (166)

What is the brachial plexus? (154)
Innervation of the thoracic limb; fusion of C6-C8 and T1-T2
Where is the subscapular nerve located? (154)
Single branch from brachial plexus C7 which supplies the subscapularis muscle
Where is the musculotaneous nerve located? (160)
Large nerve emerging from the brachial plexus (C7-C8); slightly cranial; bifurcates just prior to traveling under the biceps brachii
Where is the axillary nerve located? (162)
Emerges from the brachial plexus from C8; just caudal to the musculocutaneus nerve
