Which metatarsal heads contribute to the anterior metatarsal arch?

The correct choice highlights the significance of the 2nd and 3rd metatarsals in the formation and support of the anterior metatarsal arch. The anterior metatarsal arch is an important structural feature of the foot that contributes to its overall functionality and stability during activities such as walking and running.

The 2nd and 3rd metatarsals are centrally located and bear a considerable amount of weight during these activities. Their configuration and alignment serve to distribute forces effectively across the foot, contributing to balance and the propulsion of the body. This anatomical positioning allows for optimal load distribution, enhancing the efficiency of movement.

In contrast, while other metatarsals like the 1st and 5th do participate in weight-bearing activities, they do not centralize the anterior arch to the same extent as the 2nd and 3rd metatarsals. The role of individual metatarsal heads in forming specific arches illustrates the complexity of foot biomechanics and highlights the importance of understanding these structures for effective athletic training and rehabilitation.
