Tight junctions
Location:in the Epithelial sheet
ID the junction indicated by 2 and it’s function
Adherens junction
Function: attachments points from one cell to another cell
ID the junction indicated by 3
Desmosome
Function:strongest of the junction
ID the junction indicated by 4 and it’s function
Gap junction
Function: allows one cell to communicate with its neighbor
