I agreed too, don't know about 2


  #6

2 is terminal web formed by the insertion of actin microfilaments in microvilli into the zonula adherens

1. It is not microvilli but it is true cilia, as it is much longer and also contains a baal body which is lacking in microvilli.

2. As said above, this is the basal body.

3. Zonula occludens

4.Zonula Adherens

5. desmosomes/macula adherens
