We're going to discuss intracellular junctions or intracellular connections, also known as cell junctions. So in animal cells, there are three major types of connections or attachments. Basically, there are three major ways by which cells can connect to one another, and these include tide junctions, gap junctions, as well as desmosome. So let's discuss what each one actually looks like, what it is composed of, and what the function of each type of junction is. And let's begin by examining the tide junction. So tide junctions basically form watertight seals or watertight connections between adjacent cells.
