An electronic module consisting of chips and other electronic components mounted on a flat, rigid substrate on which conductive paths are laid between the components. A personal computer contains a main board, called the motherboard, which usually has the microprocessor on it and slots into which other, smaller boards, called cards or adapters, can be plugged to expand the functionality of the main system, allowing connections to monitors, disk drives, or a network. See also adapter, card (definition 1), motherboard.

Kosti su čvrsti organi, beličaste boje, koji čine kostur (skelet). U čovečijem telu ima oko 200 kostiju. Uloga kostiju je da telu pruže čvrst oslonac za meke delove i da u svojim dupljama zaštite organe (mozak, srce, pluća, creva, bubrege itd.). Po svome obliku kosti se dele na duge, kratke i pljosnate. Duge kosti su u udovima, rukama i nogama. Kratke kosti su u glavi.

2. Rigid connective tissue that makes up the skeleton of vertebrates; SYN. os.
3. The porous calcified substance from which bones are made; SYN. osseous tissue.
Hard connective tissue comprising the skeleton of most vertebrate animals. Bone is composed of a network of collagen fibers impregnated with mineral salts (largely calcium phosphate and calcium carbonate), a combination that gives it great density and strength, comparable in some cases with that of reinforced concrete. Enclosed within this solid matrix are bone cells, blood vessels, and nerves. The interior of the long bones of the limbs consists of a spongy matrix filled with a soft marrow that produces blood cells.
There are two types of bone: those that develop by replacingcartilage and those that form directly from connective tissue. The latter, which includes the bones of the cranium, are usually platelike in shape and form in the skin of the developing embryo. Humans have about 206 distinct bones in the skeleton, of which the smallest are the three ossicles in the middle ear.
