Histology

Question 1

Simple Epithelium

Answer 1

One layer thick

Question 2

Simple squamous

Answer 2

 one layer of flattened cells

Question 3

Simple cuboidal

Answer 3

One layer of cells about as tall as they are wide

Question 4

Simple, columnar, non-ciliated

Answer 4

One layer of non-ciliated cells that are taller than they are wide; cells may contain a microvilli

Question 5

Simple, columnar, ciliated

Answer 5

One layer of ciliated cells that are taller than they are wide

Question 6

Stratified epithelium

Answer 6

Two or more cell layers thick; only the deepest layer directly attaches to the basement membrane

Question 7

Stratified squamous keratinized

Answer 7

Many layers thick; cells in surface layers are dead, flat, and filled with the protein keratin

Question 8

Stratified squamous, non-keratinized

Answer 8

Many layers thick; no keratin in the cells; surface layers are alive, flat, and moist

Question 9

Stratified cuboidal

Answer 9

Two or more layers of cells; apical layers of cells is cuboidal – shaped

Question 10

Stratified columnar

Answer 10

Two or more layers of cells; cells in apical layers are columnar – shaped

Question 11

Pseudo stratified columnar

Answer 11

One layer of cells of varying heights; all cells attached to basement membrane; ciliated form contains cilia and goblet cells; non-ciliated form lacks cilia and goblet cells

Question 12

Transitional

Answer 12

Multiple layers of polyhedral cells (when tissue is relaxed) or flatten cells (when tissue is distended); some cells may be binucleated
