What is a key characteristic of short bones?

Short bones are primarily designed to provide shock absorption due to their shape and structure. They are roughly cube-shaped and contain a high proportion of spongy bone, which helps absorb impact and distribute forces evenly during activities. This characteristic is essential for maintaining stability and support in areas where movements involve a lot of impact, such as the wrists and ankles.

The other options do not accurately describe short bones. They are not mainly located in the arms, as that description pertains more to long bones like the humerus and radius. While short bones can assist in movement by providing a stable base and flexibility, they are not primarily dedicated to movement like long bones. Lastly, short bones are not the longest bones in the body; that title goes to long bones such as the femur.
