Freeze fracture micrograph of cell nucleus
Cell nucleus. Freeze-fracture scanning electron micrograph of a cell from a parathyroid gland. In the lower left is the nucleus (orange), studded with nuclear pores. These allow large molecules to pass through the double nuclear membrane. The thin structures in the cell cytoplasm are part of the cells endoplasmic reticulum - a network of membranes that divides the cytoplasm into compartments. The parathyroid glands are pea- shaped glands in the neck that control the level of calcium in the blood. Magnification x18, 400 at 5x7cm size. Magnification x9200 at 35mm size

EDITORS COMMENTS
This print showcases a freeze-fracture micrograph of a cell nucleus, specifically from a parathyroid gland. The vibrant orange nucleus takes center stage in the lower left corner, adorned with numerous nuclear pores that stud its surface. These tiny openings play a crucial role in allowing large molecules to traverse the double nuclear membrane. As we explore further, our attention is drawn to the delicate and intricate structures within the cell cytoplasm. These thin formations are part of the endoplasmic reticulum, an extensive network of membranes that intricately divides the cytoplasm into distinct compartments. The parathyroid glands themselves are small pea-shaped organs nestled within our necks, responsible for regulating calcium levels in our bloodstream. This microscopic glimpse into their cellular composition sheds light on their vital function and complexity. With magnification at x18,400 for 35mm size or x9200 for 5x7cm size, this image offers incredible detail and clarity. It serves as a testament to the remarkable advancements made in microscopy and highlights how science continues to unravel the mysteries of life at its most fundamental level. This awe-inspiring photograph is brought to you by Science Photo Library - not just another company but an esteemed source renowned for capturing breathtaking scientific imagery without commercial intent.
