Líffæraveffræðinnar, also known as histology, is the branch of biology that studies the microscopic anatomy of biological tissues. It involves examining cells, their structure, and how they organize to form tissues and organs. Histologists use microscopes to observe these structures, often after preparing tissue samples through processes like fixation, embedding, sectioning, and staining. These techniques enhance the visibility of cellular components and different tissue types.

The study of histology is fundamental to understanding normal physiological functions and identifying abnormalities that lead to diseases. It provides insights into how cells interact, communicate, and perform specific roles within an organism. Different types of tissues, such as epithelial, connective, muscle, and nervous tissue, are distinguished by their unique cellular arrangements and functions. Histology plays a crucial role in various medical fields, including pathology, where it is used to diagnose diseases by examining diseased tissues. It also contributes to research in developmental biology, embryology, and comparative anatomy. The detailed observation and interpretation of tissue architecture allow for a deeper comprehension of life at a cellular and tissue level.
