Answer 4

Glands help substances secrete

Answer 5

Blood vessels

Question 6

What is the Apical surface?

Answer 6

The top of the epithelial cell

Question 7

Where is The Basel surface?

Answer 7

Is located at the bottom of the epithelial cell

Question 8

What are intercellular connections?

Answer 8

Ensure tissue integrity

Question 9

The intercellular connection: Tight (occluding) junctions

Answer 9

Interlocking membrane proteins bind with adjacent plasma membranes

Question 10

Intercellular connections: Adhesion belt

Answer 10

Protein locks adjacent cells

Question 11

Intercellular connections: Gap Junctions

Answer 11

Protein channel that allows chemical communication between adjacent cells

Question 12

Intercellular connections: Desmosomes

Answer 12

Proteins that firmly attach adjacent cells

Question 13

Hemidesmosomes

Answer 13

Proteins that attach deepest epithelial cells to the base of the membrane

Question 14

Types of Epithelial Tissue: Shape

Answer 14

1 Squamous - Thin and flat

2 cuboidal - cube shaped like little boxes

3 columnar - taller then they are wide slender rectangles

Question 15

Answer 15

1 Simple

2 Stratified

Question 16

What are Exocrine glands?

Answer 16

Glands the secret into ducts and are eventually released into the epithelial surface ie sweat glands

Question 17
