Some visdev for the town of Encanto where the Madrigals live. And a very early concept of their magical house casita.

Back muscles!

SKELETAL LANDMARKS

shoulder blades: most of the upper back muscles attach to them directly, placement is affected by the arms. They can get obscured on very muscular backs, but most people these are the most dominant features!

7th cervical vertebra: neck bone that sticks out in most people, it sits in the center of that diamond shaped tendon in the middle of the trapezius

Also, obviously always keep the general shape of the ribcage and spine in mind, it was too much of a pain to draw them all in lol.

BACK MUSCLES

Erector Spinae: make the column-like structures around the spine, they extend all the way up to the neck, but you really only see the bottom part.

Latissimus Dorsi: are very thin, so most of the time you only see the structures underneath (such as the erector spinae). But when flexed, (for example, when climbing), you can see here on Jimmy Webb’s back that swooping curve it makes under the armpits.

The lats are also responsible for most of a person’s upper body strength and are the “V” shaped part of the back. For example, it’s how Bruce Lee was so strong despite being a small guy. Just look at those wings, man.

Infraspinatus, Teres Minor, and Teres Major: sit on the shoulder blade itself, and connects it to the top of the arm bone. These are responsible for a lot of the crazy shapes you see in bodybuilders’ backs.

Underneath them is the serratus anterior, which technically isn’t a back muscle but sits on the side of the ribs. These form that zig-zag pattern on the ribs that makes people look super ripped when visible with the external obliques, both wrapping around the sides of the torso. They’re not technically back muscles but fill out the silhouette, so it’s good to keep them in mind.

the glutes/butt muscles… they go farther up the back than one might assume and they, along with the pelvis, do affect the surface appearance of the lower back.

Rhomboid: simple shape, attaches from the inner edge of the shoulder blades to the middle of the spine at the 7th cervical vetebra to about the 4th or 5th thoracic vetebra. It does not overlap with the latissimus dorsi

Trapezius: divided roughly in the top, middle, and bottom sections. The top is quite thick and cylindrical and makes the sloping shape from the neck to the shoulders.

The bottom part is very thin; like the latissimus dorsi, the forms underneath it are visible when relaxed, making the rhomboid visible if it is flexed and the traps are not. Also not where the bottom part’s tendons attach to the shoulder blades; it outlines the curve of the shoulder blades even in people who are covered in brains muscles.

When fully flexed, it doesn’t taper into a point, but makes a small “w” shape at the bottom.

The 7th cervical vertebra sits at the center of the diamond-shaped tendons between the first and second sections of the trapezius. This part appears recessed in very muscular people.

Deltoid: not really a back muscle, but they overlap with the Infraspinatus and insert into the upper ridge of the shoulder blades, so it’s good to see how they interact with the others.

Ah, now for an example, featuring Thor himself. Note the curve where the traps meet the shoulder blades, the diamond-shaped tendon, and the rough “w” shaped contour of the lower back. Also note the two dimples, which is formed by the pelvis bones. They tend to be more prominent in women, although they are found in both men and women.

Try to find the back muscles on other people yourself, and then GET DRAWING

(PS, Generally it’s best to be able to simplify the forms instead of trying to render straight away - that’s how you know you really internalized the anatomy! I… honestly still don’t understand the back enough to do that yet, hence the lack of examples, unlike with the forearms post. But nonetheless, I hope that this is still useful as a general reference. I know it’s helped me at least remember what the different parts are, even if I don’t yet have a grasp of how they interact in motion!)
