De Vaucouleurs Atlas Description:

NGC 3184 has a bright core and a weak bar in the form of a broad inner oval. The oval does not stand out at first sight because it is partly bounded by two bright inner arms, which form a very open inner pseudoring . There are dust lanes in the inner oval, and there is some structure near the nucleus. The spiral arms are dominated by a two-armed pattern in the inner regions, and a complex, more ill-defined pattern in the outer regions. We favor the Sc classification because of the significant core and the relative tightness of the arms compared to later types.
