**Final Answer:**
Desmosomes, also known as macula adherens, are specialized cell junctions that facilitate strong adhesion between cells in tissues. They consist of proteins such as desmoglein and desmocollin that form adhesive bonds, contributing to the structural integrity and stability of tissues.

**Explanation:**
Desmosomes, or macula adherens, are integral components of cell junctions, particularly prevalent in tissues subjected to mechanical stress, like skin and cardiac muscle. Comprising proteins like desmoglein and desmocollin, these junctions create strong adhesion between adjacent cells.
Desmosomes' structure involves transmembrane proteins linked to intermediate filaments inside the cell. Desmogleins and desmocollins form the adhesive interface. Upon binding, they initiate a cascade of interactions, resulting in the attachment of cells.
The strength of desmosomal adhesion arises from the arrangement of cadherin molecules in the extracellular space. Their calcium-dependent interactions create sturdy connections. Desmosomes play a crucial role in tissue integrity and stability by distributing mechanical stress across tissues.
In mathematical modeling of desmosome behavior, one might consider the force required to break these junctions. Calculations often involve stress analysis formulas, considering variables like the number of desmosomes per unit area and the force applied to disrupt these bonds.
However, these calculations require specific experimental data and sophisticated models to accurately predict the force needed to break desmosomal bonds under varying conditions. Research in this area contributes to understanding cell adhesion mechanics and their implications in tissue strength and disease pathology.
