Assignment: Draw the Pecs
- Do a tracing over a model photo of the pectoralis major and all of its bundles. If you’re not sure how to do a tracing, refer back to the “How to do an Anatomy Tracing” lesson.
- Invent the pectoralis major on top of photos of Skelly. Use the photos below or if you have the Skelly app, you can create your own pose and draw the pecs on top.
I’ve provided reference photos for part 1 and 2 in the downloads. Download those and start drawing!
this is the finished assignment, some poses were quite difficult to figure out. feedback is much appreciated! <3
My pec tracing assignment. i tried to draw it on the last picture. Did I do this tracing assignment correctly ? Any feedbacks/critiques will be greatly appreciated
Repeating anatomy is useful and fun. And I hope to up my drawing skills. I love Stan’s anatomical drawings, clean, precise and simple. I forgot to add: the line on the arm is the bicipital groove on the humerus.
i wasn’t really sure if i was attaching it to the correct part on the humerus, and had a nit more trouble putting them on skelly when the arms were stretched out.
Hi everyone! I just finished reviewing these drawings for the pecs assignment after watching the critique and demo videos. I would really appreciate any kind of critique.
Just completed the Pecs assignments Did them without the demos first (Left side), then applied what I learned with the demos (Right side). Would appreciate and critiques. Thank you. :)
I just wanna mention, in the assignment image number 5, the model has a tattoo on his arm. I think it's supposed to say 超士 (super human) but instead it says 超土 (slang for super unfashionable).
i wanna show you MY PECS!!!!! feedback is very welcome :) (open original to see it in higher quality)
Hi all. Like most, I struggled a lot with understanding the twisting and the arm attachment of the pecs. Looking for more info on it, I found a biomedical research paper from 2019 that was studying variations in the muscle. It has photos of pecs from real, cleaned cadavers, and a lot of photos of the attachment itself from different views. I will post a link to it here. If this causes an issue, I understand if we have to remove it : https://pubmed.ncbi.nlm.nih.gov/31061824/ And yes, according to that research paper, it's a little different from what Stan teaches us in the video. From my understanding : (without looking at the photos, this will make no sense) 1. The attachment has 3 layers of roughly the same length overlapping each other. - The clavicular section occupies an entire layer on its own and is separate from the rest. - The rest occupy the other 2 layers, connected by a U-turn at the most distal part of the attachment. 2. There's no difference between the sternal and abdominal sections at the attachment. The "U" turn is formed roughly at 2/3rds of the sternal section, and this is where all the muscle fibers twist. 3. Because of that U turn design and the fact that the clavicular portion is on a layer of its own : - The top of the sternal portion is at the most medial point of the attachment, and the fibers attach in a more and more distal point, until the 2/3rds split. - That "2/3rds" part of the sternal portion is at the bottom of the attachment, starting to form the turn. - From that point, the rest of the fibers go in the opposite direction, from distal to medial, blending the sternal and abdominal portion as if they were the same thing. - The "last fibers" of the abdominal portion thus attach at the most medial spot too, just next to the "first fibers" of the sternal section. 4. On the photo of the 5th assignment exercise, we can see a huge dimple. I think it is not caused by what Stan explains but by tendons. One of the photos showed a muscle that had a tendonous area right at that spot. Which also explains why it only occurs on some people. Anyways, because I had conflicting information, I was confused as to whether I should follow Stan's instructions, or the information I found on the research paper. I ended up doing a mix of both, and so I got a pretty weird result. I'm not pleased with it, but I was worried I'd be thought of as "wrong" if I weren't following Stan's instructions.
Hi everyone! In this exercise, I've found it very hard visualizing the overlappings of the pec. maior in a way that shows all muscle directions and insertions while maintaining readability - any solutions for that? Any other feedback and critiques are kindly appreciated as well, of course :)
Hi, I've done the assignment for pecs anatomy lesson. Feedback is kindly appreciated!
