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.

1. Cells

• 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

1. The basic substance is gel-like material that fills the space between cells.
2. Fiber is composed of collagen, elastin and reticular fibers.
   Collagens are the major extracellular matrix proteins.
3. In epithelial tissue, extracellular matrix tiny, consisting primarily of thin Mat called the basal membrane, which lies at the heart of the epithelium.
4. In the connective tissue, extracellular matrix more numerous than cells that surrounds it.
