In anatomical textbooks the divisions of the muscular system invariably are presented from a topographical viewpoint. This is an artificial arrangement and is confusing to the student.

We classify the hyperplane arrangements between the cones of the braid arrangement and the Shi arrangement of type A n-1 which are free, in the sense of Terao. We also prove that the cones of the extended Shi arrangements of type A n-1 are free, verifying part of a conjecture of Edelman and Reiner.
