Desmosomes are cell structures that anchor neighboring cells together.
Channels that allow water and other molecules to flow between neighboring cells are not desmosomes, but gap/communicating junctions.
The plasma membranes of two adjacent cells come in contact at special sites called gap junctions or desmosomes. These structures are important for cell-cell communication and adhesion.
The stratum spinosum, or spinous layer, of the epidermis contains a high concentration of Langerhans cells, which are involved in the immune response. This layer also has numerous desmosomes, which are cell junctions that provide strength and cohesion, as well as thick bundles of keratin filaments that help with the skin's durability and protective function.
