Reflect the latissimus dorsi muscle
(video) revealing the thoracodorsal nerve
and artery and the underlying true back muscles. As you
reflect the latissimus dorsi m., clean the serratus anterior muscle along with its nerve
(long thoracic) and the lateral thoracic artery. You will study this nerve and
artery again when you dissect the axilla.
NOTE: If you do not locate the serratus anterior, you will most certainly cut it as you reflect
the latissimus dorsi m. Maybe ask for help at this point.
NOTE: The posterior inferior serratus muscle is frequently reflected along with
the latissimus dorsi m. Look for it there if you don't see it.
We will return to back muscles on the shoulder later, but you may want to clean these muscles at this
time. Demonstrate the deltoid, teres major, teres minor and long
head of the triceps.
