What is the fourth metatarsal also known as?

The fourth metatarsal is best known as the fourth digit of the foot. This bone connects to the fourth toe, commonly referred to in anatomical terms as the fourth digit. Each metatarsal corresponds to a toe, and the fourth metatarsal specifically supports the toe that is fourth in sequence, typically the ring toe.

The incorrect options refer to other parts of the foot: the hallux, which is the anatomical term for the big toe, has a different function and position, while the little toe refers to the fifth digit, which also does not correspond to the fourth metatarsal. The confusion might arise from the names associated with other digits, but the fourth metatarsal's proper designation as the fourth digit is important for accurate anatomical identification and terminology.
