0

Epithelial

Composed of cells and no direct blood supply
Form all of the internal and external body coverings

1

4 basic tissue types

Epithelial, connective, muscular and nervous tissue

2

Basal lamina

Basement membrane upon which all epithelial tissue rests on
Supporting foundation

3

Simple epithelium

Epithelial cells form a single layer resting on the basal lamina

4

Simple squamous epithelium

Consists of only one layer of flattened where the width of the cells exceed the height
Found in lining of blood vessels, walls
If the nuceli protrude, creating an irregular surface, in blood vessels may signify the beginning of life threatening problems.

5

Simple columnar epithelium

Single row of cells like buildings
Height is bigger than width
Stomach lining and intestines

6

Simple squamous epithelium

Consists of only one layer of flattened where the width of the cells exceed the height
Found in lining of blood vessels, walls of the lung alveoli
If the nuceli protrude, creating an irregular surface, in blood vessels may signify the beginning of life threatening problems.
Found in: Lung Alveoli and kidney filtration units

7

Pseudo stratified columnar epithelial

Salivary duct in male uretha

8

Pseudostratified ciliated columnar epithelium

Cilia
Lining of fallopian tub

9

Pseudo stratified columnar epithelial

Parotid Salivary duct in male uretha

10

Stratified epithelium

Two or more layers of cells extending above the basal lamina
Provides more resistence and better protection

11

Stratified squamous epithelium

Multiple layers of progressively flattened cells that have rapid mitosis and renewal
Skin mouth esophagus and vagina

12

Stratified cubodial epithelium and stratified columnar epithelium

Rare found in some salivary ducts
Pharynx larynx epiglottis
