Origin
The subscapular artery terminally bifurcates into the larger circumflex scapular artery and the smaller thoracodorsal artery.
Course
The thoracodorsal artery runs along the lateral scapular edge between the latissimus dorsi and the serratus anterior muscles. It sits posterior to the lateral thoracic artery. It then traverses through the latissimus dorsi muscle with the thoracodorsal nerve.
Branches
No named branches.
Supplied Structures
The thoracodorsal artery supplies the latissimus dorsi, teres major, and serratus anterior muscles, and contributes to the supply of the underlying intercostal muscles. It also supplies the cutaneous tissue overlying the latissimus dorsi muscle.
