the cell membrane is permeable to non-polar molecules true or false?

true

12

Junctional complexes: disk-shaped for firm intercellular adhesion eg epithelium

macula adherens (desmosomes)

13

Junctional complexes: for communication eg cardiac and smooth muscle

gap junctions

14

Junctional complexes: ring shaped increases surface area contact

zonula adherens
