  We discuss SAURON absorption line strength maps of a sample of 24 early-type
spirals, mostly Sa. From the Lick indices H$\beta$, Mg b and Fe 5015 we derive
SSP-ages and metallicities. By comparing the scaling relations of Mg b and H
beta and central velocity dispersion with the same relation for the edge-on
sample of Falcon-Barroso et al. (2002) we derive a picture in which the central
regions of Sa galaxies contain at least 2 components: one (or more) thin,
disc-like component, often containing recent star formation, and another,
elliptical-like component, consisting of old stars and rotating more slowly,
dominating the light above the plane. If one defines a bulge to be the
component responsible for the light in excess of the outer exponential disc,
then many Sa-bulges are dominated by a thin, disc-like component containing
recent star formation.
