The bones in our body have different and unique functions in our body like to protect and support weight. This is the reason why the bones in our body have different shapes. This is for them to serve particular functions. The first types are the flat bones. These bones protect the internal organs such as the heart, brain, kidney, liver, intestines and such. These bones are the skull, sternum, ribs, pelvis, etc. These are somewhat flattened and serve as protection just like what a shield does. Second are the long bones. These bones are in charge of supporting weight and facilitate movement. They are defined as the longer bones rather than wide. These include the femur, finger bones, tibia, metatarsals, humerus, radius, ulna, etc. Third on the list are the short bones. These are cube- shaped bones and are the bones responsible for the stability and some movements in an individual’s body. Some of these bones are the wrists’ carpals and the ankles’ tarsals. The irregular bones are the next type. These are the irregular shaped bones. They have the complex shapes because they also protect the internal organs. Examples of these are the vertebrae and spinal cord. Lastly, sesamoid bones are the ones that reinforce tendons. These are found in the tendons. The duty of these is to protect the tendons from stress and wear. The kneecap is an example of the sesamoid bone.
