Answer:
1. Their rounded shape allow them to joint properly with other bones, permitting a softer, better motion.
2. Provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.

The bone is a connective tissue composed of specialized cells, a mineral-salt matrix, and collagen fibers. The main functions of the bones are organ protection, structure, red and white blood cell production and support.
There are different types of bones:
- Long
- Short
- Flat
- Sesamoid
- Irregular
- Sutural
Some bones, such as the humerus and femur, are characterized by their rounded ends, also known as epiphyses (epiphysis - singular). The reason behind epiphyses is joint function. These bones are long bones, and their rounded shape allow them to ajoint properly with other bones, permitting a softer, better motion.
On the other hand, flat bones, such as vertebrae and carpals, provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.
The structure of a bone is specific to its functions in the body.
