How are the tarsal bones arranged in the foot?

• A. In a circular shape
• B. In two rows
• C. In a linear formation
• D. In a single layer

Answer: (B)

The tarsal bones in the foot are arranged in two rows: an anterior row and a posterior row. This arrangement is critical for providing both stability and mobility in the foot. The posterior row consists of the talus and calcaneus, which are essential for forming the ankle joint and bearing weight. The anterior row typically includes the navicular, cuboid, and the three cuneiform bones. This organization allows for the complex movements of the foot while ensuring it can adapt to various surfaces during walking and running. The two-row structure also supports the arch of the foot, which is vital for shock absorption and overall biomechanics. Understanding this arrangement aids in comprehending how the foot functions as a whole and how different injuries or conditions can affect its mobility and stability.
