Final answer:
The adult human body has 206 bones, divided into different categories based on their shapes. Each shape of bone has a distinct function.
Step-by-step explanation:
The adult human body has 206 bones, which are divided into five categories based on their shapes. These categories include long bones (e.g. limb bones), short bones (e.g. wrist bones), sesamoid bones (e.g. patella), sutural bones (e.g. skull), and irregular bones (e.g. vertebrae).
Each categorical shape of bone has a distinct function related to its shape. For example, long bones provide support and enable movement, whereas irregular bones protect internal organs.
