The latissimus dorsi muscles
are primarily located in the posterior torso of the body but as they
extend around the sides of the torso they can also be illustrated on
a diagram of "anterior muscles".
For a detailed illustration of the location of the latissimus
dorsi muscles see the pages about Anterior
Muscles and/or Posterior
Muscles in the Revision for Therapists Section of the IvyRose website.
