Histology Study of A tissue is a group of cells with a Matrix Composition of Tissue: • 1. Cells • 2. Fibers (formed intercellular material) • 3. Amorphous ground substance
Body Tissues • Four primary types
Epithelial Tissues • Found in different areas • Functions
Epithelium Characteristics • Cells fit • Tissue layer always has • The lower surface is bound by a
Classification of Epithelium • Number of cell layers • Shape of cells
Connective Tissue • Found • Includes the most abundant and widely distributed tissues • Functions
Connective Tissue Characteristics • Variations in blood supply • Some tissue types are • Some have • Extracellular matrix • Non-living material that surrounds living cells
Glands Gland – one or more cells that secretes a Endocrine glands Endo = Crine = Exocrine glands Exo = Crine =
Endocrine Glands Exocrine Glands
Types of Tissue Repair • Replacement of destroyed tissue by the same kind of cells • OR • Repair by dense fibrous connective tissue (scar tissue) • Type of tissue damaged • Severity of the injury
Events in Tissue Repair • Introduce clotting proteins • Wall off injured area
