Menschliches Skelett
Human skeleton
the skeleton (medical-specializedlinguistically (Anthropotomie) also Skelet; gr.: skeletos drained body, mummy) is in biology a body component, thatthe supporting structure of the organism forms. In principle there are two different kinds of skeleton: The Exoskelett, which form a sturdy, outside covering of an organism, and the Endoskelett, which are a supporting structure inside the body.

With individual cells one speaks besidesof a Cytoskelett. In the transferred sense one understands a basic structure in the technology by a skeleton also for example a building.

The simplest skeleton form, which arises particularly with smaller animals such as worms, is the hydrostatic skeleton: Herethe interior filled with liquid surrounded by muscles forms the supporting structure. Thereby the Inkompressibililtät of the water, thus the fact is used that water cannot be squeezed together as well as.

Other animals, particularly in the trunk of the Gliederfüsser (Arthropoda), developed Exoskelette.Since these “along-grow” only limited can, take place in the individual development mostly striking doing gene , with which too small the covering become during growth is stripped.

A Endoskelett consists of firm elements, which can be moved over muscles against each other. With humansand at most groups of vertebrate animals these elements are generally called bones. Further important component of Endoskeletten are the cartilages. The skeleton of certain animals, for example of sharks, is completely composed of cartilages. With mammals cartilages play oneimportant function within the joint ranges.
