What is the general term for the five long and slender bones extending from the heel?

The term that refers to the five long and slender bones extending from the heel is known as metatarsals. These bones form the midfoot and are essential in providing structure and support to the foot. Each metatarsal connects to a corresponding toe, helping with balance and mobility.

Tarsals refer to the cluster of bones located at the back part of the foot, which include the heel bone (calcaneus) and others that make up the ankle. Phalanges are the bones that form the toes themselves, with each toe containing three phalanges, except for the big toe, which has two. The term "cuboids" refers specifically to one of the tarsal bones, which is located on the outer side of the foot.

Thus, metatarsals is the correct term that specifically designates the long bones extending from the heel towards the toes.
