  The strategy adopted in the original Morris-Thorne wormhole was to retain
complete control over the geometry at the expense of certain engineering
considerations. The purpose of this paper is to obtain several complete
wormhole solutions by assuming a noncommutative-geometry background with a
concomitant isotropic-pressure condition. This condition allows us to consider
a cosmological setting with a perfect-fluid equation of state. An extended form
of the equation generalizes the first solution and subsequently leads to the
generalized Chaplygin-gas model and hence to a third solution. The solutions
obtained extend several previous results. This paper also reiterates the need
for a noncommutative-geometry background to account for the enormous radial
tension that is characteristic of Morris-Thorne wormholes.
