Nuclear envelope
Nuclear membrane surrounding the nucleus in eukaryotic cells / From Wikipedia, the free encyclopedia
The nuclear envelope, also known as the nuclear membrane,[1][lower-alpha 1] is made up of two lipid bilayer membranes that in eukaryotic cells surround the nucleus, which encloses the genetic material.

Anatomical terminology |
The nuclear envelope consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane.[4] The space between the membranes is called the perinuclear space. It is usually about 10–50 nm wide.[5][6] The outer nuclear membrane is continuous with the endoplasmic reticulum membrane.[4] The nuclear envelope has many nuclear pores that allow materials to move between the cytosol and the nucleus.[4] Intermediate filament proteins called lamins form a structure called the nuclear lamina on the inner aspect of the inner nuclear membrane and give structural support to the nucleus.[4]
