"metatarsal"的定义和意义

What is "metatarsal"?

The metatarsal refers to the long bones located in the foot, specifically in the forefoot region. There are five metatarsal bones in each foot, numbered from one to five, starting from the big toe side. These bones provide structure and support to the foot, allowing for weight-bearing and propulsion during walking, running, and other activities. The metatarsals play a crucial role in maintaining balance, absorbing impact forces, and distributing weight evenly across the foot. They also provide attachment sites for various muscles and ligaments that contribute to foot movements and stability. The metatarsals are essential for proper foot function and are susceptible to injuries such as fractures and stress fractures due to repetitive overuse or trauma.
