The inner regions of disk galaxies not only contain various types of stellar bulges, but also frequently host dense molecular gas disks - central molecular zones (CMZs). CMZs are important astrophysical phenomena. They can contain a significant fraction of a galaxy's molecular gas in high density subsystems with widely varying star formation efficiencies. CMZs both obscure and potentially fuel AGN activity, while also providing the fuel for extreme starburst events. This talk will briefly review properties of CMZs in nearby, spiral galaxies, which offer a perspective on properties of normal CMZs. I will then discuss examples of extreme situations in which CMZs support starbursts or appear to be inert to star formation but are interacting with central supermassive black holes. Understanding the range of processes that can occur in CMZs thus holds a key to understanding the development of the dense cores of galaxies.
