The function of the gap junction is to
1. performing cementing to keep neighbouring cells together
2. faciliate communication between adjoining cells by connecting the cytoplasm for rapid transfer of ions, small molecules and some large molecules
3. seperate two cells from each other
4. stop substance from leaking across a tissue

(1) muscular tissue
(2) connective tissue
(3) Epithelial tissue
(4) neural tissue
