The medial meniscus and lateral meniscus are specialized structures within the knee. These crescent-shaped shock absorbers between the tibia and femur have an important role in the function and health of the knee.
Specialization of labor is a powerful force in an economy, benefiting small and large businesses alike. Workers produce more when they occupy specialized roles, so businesses can offer higher quality products at lower prices.
Economic theory defines specialization as the production of one or just a few goods and services. In other words, it refers to how an individual, organization, state or country focuses available resources. Instead of attempting to produce and sell many different products, entities use overstock to trade for what they may lack. The system of international trade uses the concept of specialization. One country may have the resources to produce avocados at a low cost. Another country may choose to specialize in cheese. Each produces more than what they need in order to obtain other goods at a lower cost.
