Desmosomes are specialized protein structures that act like spot-welds to hold adjacent cardiac muscle cells together, resisting the mechanical stress of repeated contractions. Therefore, you would expect to see relatively large numbers of desmosomes embedded within their plasma membrane. Tight junctions are more commonly found in epithelial tissues where they provide a barrier to prevent substances from passing between cells. Glycolipids and transport proteins are not directly involved in cell-cell adhesion and do not have a significant role in resisting physical stress.
