So the inner membrane, so this is the outer membrane that is found on the side of our cytoplasm. But the inner membrane is found on the side of the fluid found inside our nucleus. And the fluid inside the nucleus is known as the nucleoplasm. So the nucleoplasm is the fluid inside the nucleus. The cytoplasm is this entire region found between the cell membrane and our nuclear membrane. Now, the inner membrane is also covered by a network of proteins known as intermediate filaments that extend throughout the entire nucleus, as shown by these extensions here.
