Epithelial Cells

Question 1

What are the two main types of epithelial cells?

Answer 1

1) simple epithelium
2) stratified epithelium

Question 2

What are the types of simple epithelium?

Answer 2

1) simple squamous epithelium
2) simple cuboidal epithelium
3) simple columnar epithelium

Question 3

What type of epithelium is in between?

Answer 3

pseudostratified columnar epithelia

Question 4

What are the types of stratified epithelium?

Answer 4

1) stratified squamous epithelia
2) stratified squamous kerantinized epithelia
3) stratified cuboidal epithelia
4) transitional epithelial

Question 5

What type of cells are these?

Answer 5

simple squamous

KEY FEATURES:

1. Flat, fried egg nuclei look, sitting on top of each other (can’t distinguish, can’t tell where one cell ends and other begins)
2. Dark pigment
3. NO SHAPE, completely flat

Question 6

What type of cells are these?

Answer 6

Simple cuboidal

KEY FEATURES:

1. As tall as they are wide, sugar cubes

Question 7

What type of cells are these?

Answer 7

simple columnar

KEY FEATURES:

1. Cells are taller than they are wide, all nuclei are closer to the bottom of the cell (rather than in the middle)
2. Nuclei perfectly aligned with each other
3. Often have microvilli (small than the nuclei)

Question 8

What types of cells are these?

Answer 8

pseudostratified epithelium

KEY FEATURES:

1. Appears to have multiple layers, but only has ONE
2. HAS CILIA (stratified do NOT)

Question 9

What type of cells are these?

Answer 9

stratified sqamous epithelium (non-kerantinized)

KEY FEATURES:

Question 10

What type of cells are these?

Answer 10

Stratified sqaumous kerantinized epithelia

KEY FEATURES:

1. Dead cells at top
2. Farther up, the cells lose nuclei

Question 11

What type of cells are these?

Answer 11

stratified cuboidal epithelial

KEY FEATURES:

1. 2-3 layers of cells

Question 12

What type of cells are these?

Answer 12

Transitional epithelia

KEY FEATURE:

1. Top layer of dome shaped cells (often denucleated)
