The Diploe can be locally absorbed and become pneumatic in some skull bones, forming inner bone cavities filled with air (Sinus). They are composed of two layers of compact bone tissue enclosing between them a variable quantity of cancellous bone (called Diploe in the skull bones). Flat bones (Ossa plana) are thin and have broad surfaces. Ossa brevia can be found in the wrist and ankle (Carpus and Tarsus). They consist of spongy bone covered by a thin layer of compact bone. ![]() Short bones (Ossa brevia) are cubical in shape. ![]() Typical long bones are the tubular bones of the limbs (Humerus, Radius, Ulna, Femur.). The ends consist of spongy bone surrounded by a thin layer of compact bone. The long cylindrical body (Corpus, Diaphysis) consists of compact bone and has a central medullar cavity. They are tubular in shape and have two ends. Long bones (Ossa longa) are longer than they are wide. Based on shape, bones (Ossa) can be classified as follows: Sound transduction - Bones in the ear play a key role in hearing.This image presents the most common types of bones. Bones serve as levers to multiply the force muscles can exert.Īcid-base balance - Bones absorb or release alkaline salts to buffer the blood against excessive pH changes. Movement - Our muscles must be attached to the rigid structure of the bones in order to operate. Mineral storage - We store excess dietary minerals, primarily calcium and phosphorus, in our bones. Blood production - Blood cells are produced by the marrow, which is located in the medullary cavity of the long bones. Protection - Our internal organs require protection, and formations such as the skull and ribs protect the brain and the heart respectively. There are various functions that these bones can serve: scapula).Īnatomists categorise bones into four main groups, long, short, flat, and irregular (everything that doesnt fall into the first three!). The name flat bones is given for obvious reasons these have broad surfaces, ideal for providing protection (ribs, skull) or as anchor points for muscles (e.g. Flat bones are one of the 4 classifications of bone and are found where protection is needed or anchoring of muscles. ![]()
