  The spatial properties of the entrances to spherically symmetric black holes
and wormholes with zero and positive masses are compared. The properties were
studied in terms of bulk and brane. The explicit expressions for the entrances
are found and it is shown that in both representations the spatial funnels of
the entrances to the wormholes are the steepest for the Schwarzschild black
holes, and the least steep for the wormholes with zero mass.
