The first and second sacral bands can be traced into the foot, the first giving rise to the musculature of its.

In a transverse section through a limb at any level all the muscle bands, both praeaxial and postaxial, which descend to that level will be cut and will lie in a definite succession from one border of the limb to the other, as is seen in Fig. 125. In the differentiation of the individual muscles which proceeds as the nerves extend from the trunk into the axial mesenchyme of the limb, the muscle bands.
