Now finally let's move on to the lowest portion of the skin the hypodermis also known as the subcutaneous layer. Basically this is the layer that insulates our body it contains the adipose cells, our fat cells as shown in the following diagram. So these orange cells are the adipose cells found in the hypodermis. Now we also have a network of fibers within this region for example we have the collagen as well as elastin fibers and what the subcutaneous layer does what the hypodermis does is it allows the dermis to basically stick to the rest of our body. So this is the lower, most portion of the skin. It contains cells such as macrophages and adipose cells.
