Tissues of the Body

Question 1

Epithelial Tissue function

Answer 1

Protects, limits diffusion, lines inside hollow organs

Question 2

Tight junction

Answer 2

Electric ion bonds preventing substances passing through adjacent cell walls

Question 3

Adherins junction

Answer 3

Plaque with Cadherin spanning across adjacent cell walls to link to its microfilaments via catenin - Prevent seperation during contractions

Question 4

Gap Junction

Answer 4

6 protiens called connexons join to form tunnels called connexins for trasnfer of information between cell walls

Question 5

desmosome

Answer 5

cadherin spans between cell walls and binds to intermediate filaments of other cell via desmoplankin - Prevent tearing forces

Question 6

Hemidesmosome

Answer 6

Cadherin spans between basement membrane and cell for integrin to promote bonding between intermediate filaments and laminin

Question 7

basement membrane components

Answer 7

basal laminina and reticular lamina

Question 8

basal lamina function and components

Answer 8

supports epithelium and provide surface for cell movement - collagen and laminin

Question 9

reticular lamina components

Answer 9

collagen and fibronectin

Question 10
