Epithelial Tissue

• Cellular

• classified by shape and number of layers

• separates the body from open spaces

Home Squamous cuboidal columnar Transitional

Page 3: Tissue project

Squamous epithelium

•Flat cells with flat nuclei

• used to cover and provide protection

•Regenerate quickly

Simple StratifiedHome epithelial

Page 4: Tissue project

Simple Squamous

•Single thin layer of Squamous epithelium

• Reduces friction

•Help in diffusion and filtration

Simple StratifiedHome epithelial Squamous

Page 5: Tissue project

Stratified Squamous

• Several layers of Squamous epithelium

• used for protection

•Most widespread of the stratified epithelia

Page 6: Tissue project

Cuboidal epithelium

• Square Cells with spherical nuclei

• Main function is secretion and absorption

Simple StratifiedHome epithelial

Page 7: Tissue project

Simple cuboidal

• Single layer of cuboidal cells

•Used for secretion and absorption

•Found in kidney tubules and related areas

Simple StratifiedHome epithelial Cuboidal

Stratified Cuboidal

• Rare

• Typically only 2 Layers thick

Transitional Epithelium

• Several layers of different epithelial cells

• Stretchy

•Lines urinary organs

Connective Tissues

• Most widely distributed and abundant tissue

•Composed of fibers and cells

•Four types

Connective tissue properHome Cartilage BloodBone

Page 15: Tissue project

Connective Tissue Proper

• Two subclasses: dense and loose

• Most connective tissue belongs to this group

•Main cell is the fibroblast

Page 16: Tissue project

Loose Connective tissue

•Loosely packed matrix

• Three types

connectiveHome Connective tissue proper Areolar Adipose Reticular connective tissue

Page 17: Tissue project

Areolar Tissue

•Gel-like Matrix

•Has all three fibers

•Wraps and cushions organs

•Most widely distributed

Dense Connective Tissue

• Tightly packed tissues

•Mainly fibers

Dense regular Dense irregularconnectiveHome Connective tissue proper

Page 21: Tissue project

Dense regular Connective tissue

• Mainly composed of collagen fibers

• Can resist tension from one direction

Page 22: Tissue project

Dense Irregular Connective Tissue

•Similar to dense regular tissue

•Can withstand tension from multiple directions

Dense regular Dense irregularconnectiveHome Connective tissue proper Dense Connective tissue

Page 23: Tissue project

Cartilage

• Can withstand large amounts of compressive force

•Tough and flexible

•Main cell is the Chondroblast

Home connective Hyaline Elastic Fibrocartilage

Page 24: Tissue project

Hyaline Cartilage

• Most abundant

• Mainly collagen fibers

•Very few cells

CartilageHome connective Hyaline Elastic Fibrocartilage

Page 25: Tissue project

Elastic cartilage

•Almost identical to hyaline cartilage

• More elastic fibers

CartilageHome connective Hyaline Elastic Fibrocartilage

Page 26: Tissue project

Fibrocartilage

• Alternating rows of cells and thick fibers

•Withstands huge amounts of compressive force

Bone

• Hard Calcified Matrix

• Mostly Collagen fibers

•Main cell is the Osteoblast

Nervous tissue

• Main component of the nervous system

• helps control the body
