Epithelial Tissue
• Cellular
• classified by shape and number of layers
• separates the body from open spaces
Home Squamous cuboidal columnar Transitional
Squamous epithelium
•Flat cells with flat nuclei
• used to cover and provide protection
•Regenerate quickly
Simple StratifiedHome epithelial
Simple Squamous
•Single thin layer of Squamous epithelium
• Reduces friction
•Help in diffusion and filtration
Simple StratifiedHome epithelial Squamous
Stratified Squamous
• Several layers of Squamous epithelium
• used for protection
•Most widespread of the stratified epithelia
Simple StratifiedHome epithelial Squamous
Cuboidal epithelium
• Square Cells with spherical nuclei
• Main function is secretion and absorption

Connective Tissues
• Most widely distributed and abundant tissue
•Composed of fibers and cells
•Four types
Connective tissue properHome Cartilage BloodBone
Connective Tissue Proper
• Two subclasses: dense and loose
• Most connective tissue belongs to this group
•Main cell is the fibroblast
connectiveHome Loose Connective tissue Dense Connective tissue
Loose Connective tissue
•Loosely packed matrix
• Three types
connectiveHome Connective tissue proper Areolar Adipose Reticular connective tissue
Areolar Tissue
•Gel-like Matrix
•Has all three fibers
•Wraps and cushions organs
•Most widely distributed

Dense regular Connective tissue
• Mainly composed of collagen fibers
• Can resist tension from one direction

Dense Irregular Connective Tissue
•Similar to dense regular tissue
•Can withstand tension from multiple directions

Cartilage
• Can withstand large amounts of compressive force
•Tough and flexible
•Main cell is the Chondroblast
Home connective Hyaline Elastic Fibrocartilage
Hyaline Cartilage
• Most abundant
• Mainly collagen fibers
•Very few cells
CartilageHome connective Hyaline Elastic Fibrocartilage
Elastic cartilage
•Almost identical to hyaline cartilage
• More elastic fibers
CartilageHome connective Hyaline Elastic Fibrocartilage
Fibrocartilage
• Alternating rows of cells and thick fibers
•Withstands huge amounts of compressive force
