  3. The first metatarsal is typically shorter and thicker than the others because it bears more weight during walking and running.
  4. Metatarsal fractures are common injuries often caused by trauma or repetitive stress.
  5. The metatarsals form part of the arches of the foot, contributing to its structure and function.
