![]() Bone is a modified form of connective tissue which is made of extracellular matrix, cells and fibers. The most robust aspect of this unit is the underlying bony architecture. Growth occurs by a lengthening of the diaphysis. 1/7 Synonyms: Cortical bone, Substantia compacta The strength, shape and stability of the human body are dependent on the musculoskeletal system. The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae. Bones that are longer than they are wide are called long bones. These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage. There are 206 bones in the human skeleton: 80 axial skeletal bones (e.g., skull, vertebral column and sacrum) and 120 appendicular skeletal bones (e.g.\( \newcommand\): Long bone: A long bone is longer than it is wide. The four principal types of bones are long, short, flat and irregular.The sternum at the front, middle of Shown are different types of bones: flat, irregular, long. Examples of irregular bones are the vertebrae, hip bones, and several skull bones. This type of ossification forms flat bones such as the temporal bone. These bones may have short, flat, notched, or ridged surfaces. Bone is the basic unit of the skeletal system and provides shape and support for the body, as well as protection for some organs Illustration shows classification of different bone types. For example, bones from archaeological sites can be used to understand what animals people ate fossilized bones can tell us how human and other primate locomotion has changed through time and bones can give us clues to how modern and ancient humans died, whether by natural causes or in the context of forensic investigations. Intramembranous ossification Where mesenchymal (embryonic) tissue is condensed into bone.
