Q

Composed of closely packed, regular shaped, connected cells

A

Epithelial tissue

20
Q

Little extracellular space

A

Epithelial tissue

21
Q

What connects the cells to the tissue

A

Basement membrane

22
Q

Function of epithelial tissue

A

Forms a protective surface layer

23
Q

On what do cells in epithelial tissue depend on and why

A

Diffusion because no blood vessels pass through the epithelial

24
Q

How are cells connected

A

By specialized structures

25
Q

In basement membrane; binds cells

A

Intercellular cement

26
Q

Prevent material from diffusing between cells lining

A

Tight junctions

27
Q

Common in skin; consists of disks

A

Spot desmosomes

28
Q

What are the two major categories of epithelial

A

Covering and lining epithelia

Glandular epithelia

29
Q

Where are covering and lining epithelia found

A
covering body surfaces 
Lining passageways; throat, intestines , vessels
Lining body cavities
Covering organs
Forming hair and nails
30
Q

On How are the different types of covering and lining epithelial based

A

Number of cell layers and shape

31
Q

What are the types of covering and lining epithelia

A
Simple epithelia 
Stratified epithelia
Squamous epithelia
Cuboidal epithelia
Columnar epithelia
32
