Trabeculae thus provide a complex series of cross-braced interior struts arranged so as to… This rapid production is made possible by the highly vascularized nature of the spongy bone, which can deliver adequate amounts of the glucose, lipids, The light weight and low density of spongy bone balances out the heavier and denser compact bone to reduce the overall weight of the The trabeculae of spongy bone tend to form along lines of stress, giving the bone strength and flexibility in that area.
Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder Spongy bone is composed of cells called osteocytes that sit in small cavities known as lacunae. The canals contain capillaries that bring in oxygen and nutrients and remove wastes. Internal structure of a human long bone, with a magnified cross section of the interior. Spongy bone, also known as cancellous bone or trabecular bone, is a very porous type of bone found in animals. It is highly vascularized and contains red bone marrow. Flat bones are thin and generally curved, with two parallel layers of compact bones sandwiching a layer of spongy bone.

The central tubular region of the bone, called the diaphysis, flares outward near the end to form the metaphysis, which contains a largely cancellous, or spongy, interior. The Haversian system, consisting of inorganic substances arranged in concentric rings around the Haversian canals, provides compact bone with structural support and allows for metabolism of bone cells.



spongy bone: [ bōn ] 1. the hard, rigid form of connective tissue constituting most of the skeleton of vertebrates, composed chiefly of calcium salts. Transverse branches are known as Volkmann canals.This article was most recently revised and updated by

To examine this finding further, recent research has compared the trabecular density of modern human skeletons to those of chimpanzees and early humans who lived millions of years ago. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. Osteocytes (mature bone cells) are found in tiny cavities between the concentric rings.
2. any distinct piece of the skeleton of the body.

The lacunae and their accompanying osteocytes are housed in the trabeculae matrix of the bone along with the bone marrow. Spongy Bone. This honeycombed bone is termed cancellous or trabecular. Usually, spongy bone is situated at the end of long bones, with the surrounding of harder compact bone. In mature bone, trabeculae are arranged in an orderly pattern that provides continuous units of bony tissue aligned parallel with the lines of major compressive or tensile force. Biologydictionary.net, May 07, 2017. https://biologydictionary.net/spongy-bone/. At the end of the bone is the epiphysis, which in young people is separated from the metaphysis by the physis, or growth plate. Spongy bone, also known as cancellous bone or trabecular bone, is a very porous type of bone found in animals. The mineral content of blood must be tightly regulated to ensure proper functioning of the muscles and The modern human skeleton is unique in that it has a low trabecular density compared to its size. Inside spongy bone, red blood cells are produced in the red bone marrow at a rate of about 2 million per second. Most of the bones of the skull are flat bones, as is the sternum. In addition to long bones, the four other types of bones in the human skeleton are short bones (the tarsal bones of the wrists and feet), flat bones (skull, rib cage, sternum, scapula), sesamoid bones (knee cap) and irregular bones ().
