  In this work we compute the effective action describing the low-energy brane
Goldstone-boson dynamics. The Goldstone bosons or branons appear because the
brane spontaneously breaks the translational invariance along the extra
dimensions. We discuss the Higgs-like mechanism in which the Kaluza-Klein gauge
fields absorb the Goldstone bosons and acquire mass. We also present the
explicit form of the effective action describing the low-energy interactions
between the three-brane Goldstone bosons and the Standard Model fields. In
addition to the branons, two new kinds of states arise corresponding to
Skyrmion-like solutions and wrapped states. We study the main properties of
these states, their geometrical interpretation and the relations between them.
