Encounters #3

This past week, we've been learning about the various types of junctions found in between cells.

Learning about this, it made me think of the highways, and roads we drive on, with all of its traffic rules and regulations. There are different types of regulations implemented that maintain a safe driving environment. And like cell junctions, there are certain things related to traffic regulations that help, particularly the lane markings.

For example, in tight junctions (zonula occludens), it is hard or impossible to pass through or communicate. Just like these junctions, there are yellow lines that prevent any lane changing and it is never to be crossed. Another comparison can be found in the gap junctions, which allow for cell to cell communication. This can be compared with the white lane separations as there is a passage of flow or movement allowed.

It is indeed interesting how cell biology can relate to everyday things.
