latissimus dorsi muscle
The latissimus dorsi is the larger, flat, dorso-lateral muscle on the trunk, posterior to the arm, and partly covered by the trapezius on its median dorsal region. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

Questions
Where is the latissimus dorsi muscle?
It sits within the muscular system. Positioned deliberately as part of this species body plan.
What does the latissimus dorsi muscle connect to?
A kind of: muscle of shoulder, skeletal muscle organ, vertebrate and skeletal muscle tissue.
Is the latissimus dorsi muscle the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
