osteon









































the osteon or haversian system (named for clopton havers) is the fundamental functional unit of much compact bone. osteons are roughly cylindrical structures that are typically several millimeters long and around 0.2 mm in diameter. they are present in many bones of most mammals and some bird, reptile, and amphibian species.

each osteon consists of concentric layers, or "lamellae", of compact bone tissue that surround a central canal, the haversian canal. the haversian canal contains the bone's blood supplies. the boundary of an osteon is the cement line.

since 500 b.c., some researchers have believed that the physical condition of the fingernails and toenails can indicate various systemic diseases. careful examination of the fingernails and toenails may provide clues to underlying systemic diseases , since some diseases have been found to cause disruptions in the nail growth process. the nail plate is the hard keratin cover of the nail. the nail plate is generated by the nail matrix located just under the cuticle. as the nail grows, the area closest to becoming exposed to the outside world (distal) produces the deeper layers of the nail plate, while the part of the nail matrix deeper inside the finger (proximal) makes the superficial layers. any disruption in this growth process can lead to an alteration in the shape and texture.
