Description:
Single layer of flattened cells with disc-shaped central nuclei. |
Simple squamous epithelium
|
|
Location:
Alveoli of lungs, kidney glomeruli, lining of heart and blood vessels. |
Simple squamous epithelium
|
|
Function:
Allows passage of materials by diffusion and filtration in sites where protection is not important. |
Simple squamous epithelium
|
|
Description:
Single layer of cubelike cells with large spherical central nuclei. |
Simple cuboidal epithelium
|
|
Location:
Kidney tubules, ducts and secretory portions of small glands, and ovary surface. |
Simple cuboidal epithelium
|
|
Function:
Secretion and absorption. |
Simple cuboidal epithelium
|
|
Description:
Single layer of tall cells with oval nuclei; some cells bear cilia; may contain mucous secreting glands called goblet cells. |
Simple columnar epithelium
|
|
Location:
Nonciliated type lines most of digestive tract { from stomach to anal canal }; ciliated variety lines small bronchi, uterine tubes, and some regions of uterus. |
Simple columnar epithelium
|
|
Function:
Absorption; secretion of enzymes, mucous, and other substances; ciliated types propel mucous and reproductive cells by ciliary action. |
Simple columnar epithelium
|
|
Description:
Single layer of cells of differing heights, some not reaching the free surface; nuclei seen at different levels; may contain goblet cells and bear cilia. |
Pseudostratified epithelium
|
|
Location:
Ciliated variety lines the trachea and most of the upper respiratory tract; nonciliated type in ducts of large glands, parts of male urethra. |
Pseudostratified epithelium
|
|
Function:
Propulsion of mucous by ciliary action. |
Pseudostratified epithelium
|
|
Description:
Several layers of cells. The cells at the free surface are squamous. |
Stratified squamous epithelium
|
|
Location:
Forms the moist linings of the esophagus, mouth, and vagina; forms the epidermis of the skin. |
Stratified squamous epithelium
|
|
Function:
Protects underlying tissues in areas subjected to abrasion. |
Stratified squamous epithelium
|
|
Description:
Usually 2 layers of cube- shaped cells. |
Stratified cuboidal epithelium
|
|
Location:
Largest ducts of sweat glands, mammary glands, and salivary glands. |
Stratified cuboidal epithelium
|
|
Function:
Protection |
Stratified cuboidal epithelium
|
|
Description:
Several layers of cells; basal cells usually cuboidal; superficial layers elongated and columnar. |
Stratified columnar epithelium
|
|
Location:
Rare in body; small amount in male urethra and in large ducts of some glands |
Stratified columnar epithelium
|
|
Function:
Protection and secretion |
Stratified columnar epithelium
|
|
Description:
Resembles both stratified squamous and stratified cuboidal; basal cells cuboidal or columnar; surface cells cube- like or squamous -like depending on degree of stretching. |
Transitional epithelium
|
|
Location:
Lines the ureters, bladder, and part of urethra. |
Transitional epithelium
|
|
Function:
Stretches readily and permits distension of urinary organ by contained urine. |
Transitional epithelium
