The idea of the stellar atmosphere as a transition zone between the quasi-equilibrium stellar interior and the wholly nonequilibrium interstellar medium is developed. The transition is between a primarily-storage, and a primarily-propagation, configuration for the energy associated with each of the radiation and massfluxes. Each phase of the transition, for the radiative flux, gives rise to one region of the photosphere; for the mass-flux, to one region of the hylosphere. A schematic outline of the phases is provided.
