MUSE on the VLT enables the 'intensive' spectroscopic exploration of gas and stellar properties of nearby galaxies on physical scales in Sequence. We use the MAD data to investigate, within the inner half-mass radius, the local relation between stellar kinematics, mass density, metallicity and age, and ionized gas in/out-flows, kinematics and metallicity. We compare azimuthally-averaged radial gradients of key diagnostics and discuss the origin of such gradients in the light of the 2-D structure that is revealed by the MUSE 2 data, including features such as shocks, metal poor/rich inflows/outflows, relics of merging events or metal-enriched star forming rings. Most of these features are lost in 'extensive' (i.e. large numbers but) lower resolution IFU surveys. We connect the results with global galaxy properties such as stellar mass, SFR and bulge/disk kinematics, and discuss the implications of our results for the secular growth of inner structure -including bulges- within the disks.
