Extrinsic Back Muscles

Alright, it’s time to hit the ground running. The bootcamp is over and orientation is in full swing. To help me remember the muscles, nerves, and arteries that we reviewed in class I’m going to share them here.

Quick disclaimer, all drawings are done by me, while I try to remain as accurate as possible, I am only a student. There are natural human variations and differences between textbooks. That being said, I hope my illustrations can be of some help.

This post covers the Extrinsic Back Muscles.

After the superficial back muscles are the 2 intermediate back muscles, Serratus Posterior Superior and Serratus Posterior Inferior. Serratus means ‘saw-tooth’ and refers to the appearance of the Serratus muscles.

I apologize for the crappy handwriting, but I have been told that writing instead of typing your notes is better for your memory.
