Q

ET

A

Own nerve supply
A vascular or lacks it’s own blood supply
High rate of cell division for renew and repair

18
Q

First name

A

The number of cell layers present

19
Q

2nd name

A

Describes the shape of its cell

20
Q

Simple epithelium

A

Single layer of the cels

Function– diffusion, osmosis, filtration, secretion, or absorption

21
Q

Pseudo stratified epithelium

A

Multiple layers because cell nuclei at different levels, but is only one layer

22
Q

Stratified epithelium

A

Two or more layers of cell

23
Q

Squamous

A

Thin cells arranged like floor tiles

Allows for rapid passage substance

24
Q

Cuboidal

A

As tall as they are wide, shaped like cubes or hexagons

Mainly function in secretion or absorption

25
Q

Columnar

A

Much taller than they are wide, like columns
May have cilia or micro villi
Function for secretion and absorption

26
Q

Transitional

A

Cells change shape, transition for flat to a small size

27
Q

Simple squamous epithelium

A

Single layer of cell resembles a tiled floor on the surfaces

28
Q

Nucleus

A

Is centrally located and appears flattered oval or sphere

29
Q

Endothelium (inner covering)

A

Provides a slick, friction reducing lining in the lymphatic vessels, blood vessels and heart

30
Q

Mesothelium (middle covering)

A

Found in the serous membranes lining the ventral body cavity and covering its or organs

31
Q

Simple cuboidal epithelium

A

Single layer of tall cells

32
Q

Nonciliated

A

Line most of the digestive tract

33
Q

Ciliated

A

Line very small bronchi ( lungs ) and uterine tubes

34
Q

Keratinization

A

The process in which the cytoplasm of the cells is replaced by the protein

35
Q

Keratin

A

Fibrous protein that helps give the epidermis it’s protective properties

36
Q

Basal cells

A

Are more active in mitosis and produce cells that move toward the surface

37
Q

Function

A

Protects underlying tissues in areas subjected to abrasion

38
Q

Keratinized

A

Forms the epidermis of the skin

39
Q

Nonkeratinized

A

Esophagus , mouth ,Hand , vagina

40
Q

Stratified cuboidal

A

Apical layers are cuboidal

Functions in protection

41
Q

Stratified columnar

A

Columnar = apical layer only
Basal layer has shorten
Function is protection and secretion

42
Q

Transitional

A

Found only in urinary system
In relaxed state cells appear cuboidal or columnar
Upon stretching cell appear squamous
Ideal for hollow structure subjective to expiation
