VIII. Body Tissues Tissues = Four types

A. Epithelial Tissues 1. Locations coverings linings Skin & Glands 2. Characteristics Cell Density: Surfaces: Apical & Basal Avascular Regeneration:

3. Classification cell layers Simple: Stratified: Cell Shape Squamous Cuboidal Columnar A B C Figure 3.17a

4. Simple Epithelia a) Simple Squamous Forms membranes Function Examples:

Simple Epithelia … b) Simple cuboidal Functions: Examples:

5. Stratified Epithelia a) Stratified squamous Cell Shape: Function: Locations

6. Glandular Epithelium Gland secreting a particular product Types Exocrine Endocrine

VIII. Body Tissues … B. Connective Tissue 1. Characteristics Cell Density Blood Supply Location: Functions

Connective Tissue Characteristics 2. Extracellular matrix = Material between cells Protein Fibers Collagen (white) fibers Elastic (yellow) fibers

Connective Tissue Types 3. Bone (osseous tissue) Composed of Bone cells in lacunae Hard matrix Minerals: Fibers: Function:

Connective Tissue Types 4. Cartilage Compressible matrix: Cells in lacuna Locations

Connective Tissue Types 5. Dense connective tissue (fibrous) Fibers: Fibroblasts: Locations Tendons Ligaments Dermis

Connective Tissue Types 6. Areolar location Fibers Functions:

Connective Tissue Types 8. Blood (vascular tissue) Matrix: Fibers: Functions:

D. Muscle Tissue Functions: Cells shape: Three types

Muscle Tissue Types 1. Skeletal muscle Conscious control Function: Striated

Muscle Tissue Types 2. Cardiac muscle Conscious control: Location: Function: Intercalated Discs: Striated:

Muscle Tissue Types Figure 3.20b

Muscle Tissue Types 3. Smooth muscle Conscious control: Locations: Function: Cell Shape

E. Nervous Tissue Location Cells: Cell Body Processes Function: Irritability Conductivity

IX. Events in Tissue Repair Inflamation Capillaries permeable Blood clot Scab forms Granulation tissue New capillaries Make collagen fibers Clot dissolves Regeneration Regeneration of surface epithelium Scab detaches Tissues: epithelial, connective except cartilage

Tissues with No to Poor Regeneration Fibrosis = Repair by dense connective tissue = scar tissue Tissues Cardiac muscle Nervous Skeletal muscle
