small channels that allow
molecules to pass
between cells

Answer 12

Gap junctions: (connexins)

Question 13

allow cells to communicate

most common cell junctions

Answer 13

Gap junctions: (connexins)

Question 14

covers body surfaces and
lines hollow organs, body
cavities, and ducts; it also
forms glands.

Answer 14

Epithelial tissues

Question 14

tetratransmembrane proteins that assemble into hexameric pore-forming structures known as connexons or hemichannels

Answer 14

Connexins

Question 15

Function of epithelial tissues

Answer 15

allows the body to interact
with both its internal and
external environments.

Question 16

Hallmarks of epithelial tissues

Answer 16

Cover and line body surfaces

Often form sheets with one free surface,
the apical surface, and an anchored
surface, the basement membrane

Avascular (no blood supply)

Regenerate easily if well nourished

Question 17

Arrangement of layers

Answer 17

Simple

Pseudostratified

Stratified

Question 18

a dense, sheet-like form of extracellular matrix (ECM) that underlie epithelia and endothelia, and surround muscle, fat and Schwann cells

Answer 18

Basement membranes

Question 19

lines the lumen of sac- and tube-shaped organs and the inner surfaces of the body cavities

Answer 19

Apical surfaces

Question 20

Consists of only a single later of cells; Secretion, adsorption

Answer 20

Simple epithelium

Question 21

Consists of more than one layer of epithelial cells, with some cells sitting on top of others

Answer 21

Stratified epithelium

Question 22

Appeared to be 2 or more layers of cells, some are tall and other are short

Answer 22

Pseudostratified epithelium

Question 23

Cell shapes

Answer 23

Squamous, Cuboidal, Columnar

Question 24

Cells are flat or scalelike; rapid passage of substances

Answer 24

Squamous

Question 25

Are cube-shaped; may have microvilli; secretion and adsorption

Answer 25

Cuboidal

Question 26

are tall and thin, cell tends to be taller than they are wide; secretion and adsorption; protect underlying tissues

Answer 26

Columnar

Question 27

Change shape, from squamous to cuboidal and back, as organs such as the urinary bladder stretch to a larger size and then collapsed to a smaller size

Answer 27

Transitional cells
