Bones can be classified into four categories that are based on their shapes. The first category of bones is the long bone; they have long Diaphysis and expanded Epiphysis. Long bones make up arms and legs. The second category is short bones; they are similar to long bones in shape but are smaller and have less prominent Epiphysis. They make up fingers, wrists, and feet. The third category is flat bones, which are plate like and have broad surfaces. These bones make up the ribs, scapula, and the skull bones. The fourth category of bones is the irregular bones; these bones come in a variety of shapes and are often connected to other bones. This category includes facial bones and vertebrae. In addition, some individuals recognize a fifth category called the round or sesamoid bones. These bones are small and are found in tendons adjacent to joints.<ref>Hole, John W.

The human skeletal system is comprised of many tissues including bone tissue, cartilage, connective tissue, blood and nervous tissue. These tissues work together to provide the body structure for muscles and joints.
Bone Classification
Bones can be classified into four categories that are based on their shapes. The first category of bones is the long bone; they have long Diaphysis and expanded Epiphysis. Long bones make up arms and legs. The second category is short bones; they are similar to long bones in shape but are smaller and have less prominent Epiphysis. They make up fingers, wrists, and feet. The third category is flat bones, which are plate like and have broad surfaces. These bones make up the ribs, scapula, and the skull bones. The fourth category of bones is the irregular bones; these bones come in a variety of shapes and are often connected to other bones. This category includes facial bones and vertebrae. In addition, some individuals recognize a fifth category called the round or sesamoid bones. These bones are small and are found in tendons adjacent to joints.[1]
