Study Notes
Overview of Tissue in Biology
- Tissue is an intermediate level of biological organization between cells and organs.
- It is composed of similar cells and their extracellular matrix that perform a specific function.
- Organs are formed by the grouping together of multiple tissues.
- The word "tissue" comes from the French word "tissu", meaning "to weave".
- The study of tissues is known as histology or histopathology in relation to disease.
- Xavier Bichat is considered the "Father of Histology".
- Plant histology is studied in plant anatomy and physiology.
- Paraffin blocks, histological stains, and optical microscopes are traditional tools for studying tissues.
- Electron microscopy and immunohistochemistry are modern advancements in tissue analysis.
- Tissues can be analyzed to understand the structure and function of organs and to diagnose diseases.
- The hierarchical organization in biology is: Cells < Tissue < Organ < Organ System < Organism.
- Understanding tissue organization is crucial in comprehending the complexity of living organisms.
