Nuclear envelope
The nuclear envelope consists of two membranes, an inner and an outer nuclear membrane, which are separated by the perinuclear space. The perinuclear space and outer nuclear envelope are continuous with the RER. The nuclear envelope has periodic openings called nuclear pores. 10,000x
