connective tissue

Question 17

basement membrane

Answer 17

Barrier between epithelium and connective tissue

Question 18

epithelia is Avascularity

Answer 18

means having no blood cells

Question 19

since epithelia lack blood vessels where do they get nutrients

Answer 19

Nutrients obtained across apical surface or from basal
surface

Question 20

epithelia have Extensive innervation

Answer 20

Richly innervated; detect changes in environment

Question 21

epithelia have High regeneration capacity which means they

Answer 21

Continual replacement of lost cells

Question 22

simple epithelium

Answer 22

One cell layer thick; all cells contact basement membrane
* Filtration, absorption, or secretion is primary function

Question 23

stratified epithelium

Answer 23

Two or more layers of epithelial cells
* Only basal layer in contact with basement membrane
* In areas subjected to mechanical stress

Question 24

squamos

Answer 24

Flat, wide, irregular in shape
* Nucleus flat

Question 25

psuedo stratified

Answer 25

Appears layered * All cells contact basement membrane, but may not reach apical surface

Question 26

columnar

Answer 26

Slender and taller than they are wide *Nucleus oval; oriented lengthwise in basal region

Question 27

Answer 27

type of epithelial cell that are About as tall as they are wide and their Nucleus is spherical and in center of cel

Question 28

transitional cells can change _____ depending on stretch of epithelium

Answer 28

shape

Question 29

simple squamos is the

Answer 29

Thinnest barrier

Question 30

simple squamos allows

Answer 30

rapid movement of molecules across surface

Question 31

Simple Cuboidal Epithelium

Answer 31

Designed for absorption and secretion * Ideal for structural components of glands

Question 32

Simple Columnar Epithelium

Answer 32

Oval nucleus, lengthwise in basal region Ideal for secretory and absorptive functions Two forms: * Nonciliated * Ciliated

Question 33

Ciliated Pseudostratified Columnar Epithelium

Answer 33

Contains cilia on apical surface Protective functions Goblet cells secrete mucin * Traps foreign particles moved by cilia Located in large passageways of

Question 34

Stratified Squamous Epithelium

Answer 34

Basal layers with cuboidal shape Apical cells with squamous shape Protects against abrasion and friction Stem cells in basal layer continuously divide * Replace lost cells at surface Exists in keratinized and nonkeratinized forms
