Microstructures and macrostructures are linked together by an intermediate mechanism of societal patterns of relationships known as mesostructures.
Mesostructures are arrangements of social relationships between groups of individuals who often do not know each other well and frequently do not interact in person. They are intermediate-size or complex structures or superstructures. The study of sociology and the examination of these structures enables sociologists to appreciate the interconnectedness of tiny microstructures and contributes to the operation of megastructures, also referred to as macrostructures.
The bureaucratic structures in our socio-political system, university colleges, and schools are examples. Indirect relationships and no acquaintances are the principal hallmarks of this type of social structure.
