The concept of a nucleus spans multiple scientific disciplines, appearing in atomic structure, cellular biology, and neuroscience, as illustrated in this detailed diagram. This image compares the nucleus of a helium atom, a cell, and specific nuclei within the brain, offering a unique perspective on its role across scales. Exploring these representations enhances understanding of fundamental building blocks, cellular function, and neural organization in the central nervous system.

Endocytosis is a critical active transport process that allows cells to engulf extracellular materials, playing a pivotal role in nutrient uptake, immune response, and cellular communication. The diagram illustrates three distinct forms—phagocytosis, pinocytosis, and receptor-mediated endocytosis—each with unique mechanisms and selectivity levels for internalizing substances. This article provides an in-depth exploration of these processes, their anatomical structures, and their significance in maintaining cellular function and physiological balance.
