Microscopic anatomy of a tissue
Fabric is a group of interconnected cells that perform similar functions in the body. For example, muscle cells group together and form a muscle that functions to move the body parts. In the tissues of the body consists of cells and intercellular substance.
- Cells are the smallest structural unit of living matter, able to act independently.
- Cell groups together make up the fabric.
- Four main types of epithelial tissue, connective, nervous and muscular tissues.
2. Extracellular Matrix. Tissue does not consist exclusively of cells. The gel-like substance that contains bound protein fibers surrounds most of the cells.
- Extracellular matrix in meshlike material that surrounds the cells (Fig. 2-1). This framework for a cell. This material helps to keep together the cells and provides a framework within which cells can migrate to and interact with each other.
- Extracellular matrix consists of the basic substance, and fiber.
- The volume of Extracellular matrix
- The basic substance is gel-like material that fills the space between cells.
- Fiber is composed of collagen, elastin and reticular fibers.
Collagens are the major extracellular matrix proteins.
- In epithelial tissue, extracellular matrix tiny, consisting primarily of thin Mat called the basal membrane, which lies at the heart of the epithelium.
- In the connective tissue, extracellular matrix more numerous than cells that surrounds it.
