The nuclear envelope is the double-layered membrane surrounding the nucleus in eukaryotic cells. The space between the two layers of the membrane is called the perinuclear space and the outer membrane is continuous with the rough endoplasmic reticulum membrane. The nuclear envelope contains nuclear pores that allow and regulate the transport of materials such as RNA between the nucleus and the cytoplasm. Extending from the nucleus out into the cytoplasm is the endoplasmic_reticulum - a large membrane-bound compartment which is the site for lipid synthesis and production of membrane-bound proteins and secretory proteins.
The nuclear membrane gets its strength from the nuclear lamina. The nuclear lamina is a network of intermediate filaments, made up of proteins, that form a thin but strong sheet found inside of the inner nuclear membrane[1].
