Top 10 Commonly Confused Words in Histology 1. Epithelium vs. Endothelium Epithelium and endothelium are two terms that often cause confusion. Epithelium refers to the tissue that covers the body's surfaces, both internal and external. On the other hand, endothelium specifically refers to the tissue that lines the inner surface of blood vessels and lymphatic vessels. While both are types of lining tissues, their locations and functions differ. 2. Nucleus vs. Nucleolus The nucleus and nucleolus are vital components of a cell, but they have distinct roles. The nucleus is the cell's control center, containing the genetic material. It regulates cell activities and is often referred to as the 'brain' of the cell. In contrast, the nucleolus is a structure within the nucleus. It plays a crucial role in ribosome production, which is essential for protein synthesis. 3. Neuron vs. Neuroglia Neuron and neuroglia are both types of cells found in the nervous system. Neurons are responsible for transmitting electrical signals, enabling communication within the nervous system.
