Metatarsus
Metatarsus
The Metatarsus (pronounced: meh-tahr-sus) is a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes.
Etymology
The term "Metatarsus" is derived from the Greek words "meta," meaning after, and "tarsos," meaning ankle. This refers to the position of these bones in the foot, which is after the tarsal bones and before the phalanges.
Anatomy
The metatarsus consists of five cylindrical bones which are numbered from the medial side (side of big toe): the first, second, third, fourth, and fifth metatarsal. These bones are often broken down into three parts: the base, the body or shaft, and the head. The base is the part closest to the ankle; the body is the long, slender, middle portion; and the head is at the end of the metatarsus, closest to the toes.
