  An earlier study [Rahaman et al. (2014) & Kuhfittig (2014)] has demonstrated
the possible existence of wormholes in the outer regions of the galactic halo,
based on the Navarro-Frenk-White (NFW) density profile. This paper uses the
Universal Rotation Curve (URC) dark matter model to obtain analogous results
for the central parts of the halo. This result is an important compliment to
the earlier result, thereby confirming the possible existence of wormholes in
most of the spiral galaxies.
