Why do you think gap junctions might be important to cells that are part of a multi-
cellular tissue like neurons?
They allow chemical messages to be sent from one cell to another, so that
messages can travel the body through neurons
They hold cells so tightly together that pathogens cannot invade
They are strong attachments, important in cells that experience a lot of strain
and movement, which neurons do since they extend through all limbs
