Intercellular Junctions

We help cells stick to each other and also communicate.

[Intercellular Junctions @plasmodesmata17]

Plasmodesmata are lined with the plasma membrane.

Gap junctions and plasmodesmata have similar very similar functions, but the structure of them are very different from one another.

FUN FACT:
Without tight junctions between cells, your bladder would not be able to hold urine.

Although tight junctions do not provide access for things to travel from one cell to another, they are still very important. They create a watertight seal between cells to keep liquid from passing between two cells.

Cells without intercellular junctions would be like a building with several rooms, but no doors or windows. Nobody could go in or out!

The cytoskeleton works with desmosomes. They are connected so the desmosomes can be anchored in the cell.

Desmosomes are the MOST important when it comes to holding cells together. They form a very strong bond and are also anchored in the cytoplasms of the two cells.

Here is a picture of tight junctions binding two animal cells together:

Tight junctions bind cells together, kind of like a zipper.

The small spaces in the cell wall shown in the picture below are the plasmodesmata.

Without intercellular junctions, you would just be a single cell.

Cell junctions let certain nutrients in and out of the cell, while keep others from coming in or leaving the cell.

@Mightycondria1 But are you really the #powerhouseofthecell....

[Intercellular Junctions @plasmodesmata17]

The cytoplasm of two cells are connected by plasmodesmata in plant cells and gap junctions in animal cells.

[Intercellular Junctions @plasmodesmata17]

Gap junctions are primarily what help cells communicate (similar to plasmodesmata in plants). They provide a channel in which small molecules like amino acids and sugars can pass from one cell to the next.

FUN FACT:
When you tear a muscle, desmosomes between muscle cells are sometimes ruptured.

Desmosomes, which are in animal cells, are also called anchoring junctions. They bind two cells together, while keratin proteins anchor them in the cytoplasm to keep them in place.
