Why are short bones well suited to an area like the wrist? Why are long bones more suited to areas like the lower arm?

Short bones are well suited for the wrist because they provide stability, and long bones are well suited for the arm because they can support a lot of weight.

Explanation:

Bones have different shapes and lengths. The reason for this is that their design has a specific function in the body. One way to classify bones is according to their shapes, there are short bones, long bones, flat bones, and irregular bones.

Short bones are approximately equal in length, width, and thickness. They provide stability and some restricted movements, owing to this fact, they are present in our ankles and wrists so that we can stand straight and have proper support when we use our wrist to stabilize ourselves or hold to an object.

In long bones, the length predominates over thickness and width. They work as levers being able to support a lot of weight. This is why long bones are suited for the lower arm, when the arm muscles contracts they can lift heavy things, the same happens with the bones in our legs, they are long because they have to hold the weight of the body.
