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!

And own corrections. Anything else i am missing?

This one has a twisted sternal and abdominal portion, correct?

I believe I am misunderstanding the concept of "muscle fibers taking a sharp turn inward". Please help me understand it. Is there a top view available when this occurs?

Looks like you’re getting it! I sketched this up to maybe clarify things a little more. Hope it helps.

Should I do this? When a muscle is stretched, it becomes thinner at the ends and thicker in the middle.

Hiyah! Tried doing some other examples after I realized that my volumes were completely off. I'm probably going to watch and rewatch Stan's critique for this one, but I would really appreciate some feedbacks and/ or retakes :) Hope y'all are well ! Hugo

This is my take on the assignment. I feel I need to study the demonstration videos before I move on to the next lesson. Also I want to add that I did some master studies of my favorite artists before doing the assignment and it helped me a lot to visualize the shape of the muscle.

Looks great!

Here's part two of the assignment. I have made some adjustments after watching the demonstration video. I found the 'armpit bundle' to be the biggest challenge, as there is some curvature there even when the medial parts of the muscle group are stretched or contracted.

Looks great! Nice twisting of the different sections of the pecs!

Here's the first part of my assignment. I decided to start by drawing in the ribcage, clavicles, and humeri (?) to help find the origin and insertion points for the pecs.

It's called "humerus" cuz it's funny.

Great idea! Good work.

Really like the type of the assignment. The second part was really paying off!

This is a nice start. You drew the 3 parts of the pectoralis muscles in the right spots. Here’s how I might draw the pecs on this skeleton. They cross over each other sorta like a fan. I over exaggerated it a bit. Maybe this helps. Keep it up!

Study note. When I started the assignment, I realized that I didn’t really understand the pec muscles. So, I re-watched this video to figure out where and which muscles they are. I tried to simplify them in one photo. After this, I finally understood them a little bit. Now, I need to redraw the assignment.
