Some sources consider the ankle and wrist bones to be a part of the feet and hand bones. If you were to consider the ankle and wrist bones as part of the feet and hand bones then the total number of bones in the feet would be 52,and the total number of bones in the hands would be 54.

When I was solving this exercise, I thought it was interesting that there are the same number of bones in a human hand as there are in a human foot.

• 13. Bones in a Human's Hands, Wrists, Feet, and Ankles

The skeletal system is a complex work of nature with the hands and feet being the most intricate. What percent of the bones are in the hands, wrists, feet, and ankles? (See Example 3 and Example 4.)

• Worked-Out Solution

Begin by adding the bones in the hands, wrists, feet, and ankles.

To find the percent that these bones make up of the total, divide 106 by the total number of bones in the human body.

Of the bones in the body, about 51.5%, or roughly half, are in the hands, wrists, feet, and ankles.
