Nuclear envelope
This freeze fracture image of a lymphocyte shows a fracture plane where separation has occurred between the outer nuclear membrane and the inner nuclear membrane, thereby revealing the perinuclear space around the nucleus. Organelles, e.g., mitochondria and vesicles, are also visible in the cytoplasm. 12,000x
