Histology is the study of the tissues of the body and how these tissues are arranged to constitute organs. The Greek root histo can be translated as either “tissue” or “web” and both translations are appropriate because most tissues are webs of interwoven filaments and fibers, both cellular and noncellular, with membranous linings. Histology involves all aspects of tissue biology, with the focus on how cell’s structure and arrangement optimize functions specific to each organ.
From a single cell to a baby in nine months, the developmental process represents an amazing integration of increasingly complex phenomena. The study of these phenomena is called embryology, and the field includes investigations of the molecular, cellular, and structural factors contributing to the formation of an organism. These studies are important because they provide knowledge essential for creating health care strategies for better reproductive outcomes.
