bone

Etymology: AS, ban

1 the dense, hard, and somewhat flexible connective tissue constituting the framework of the human skeleton. It is composed of compact osseous tissue surrounding spongy cancellous tissue permeated by many blood vessels and nerves and enclosed in membranous periosteum.

2 any single element of the skeleton, such as a rib, the sternum, or the femur. Also called (Latin) os. See also connective tissue.

bone,

n 1. the material of the skeletons of the tissue composing bones.
n 2. dense, hard, and slightly elastic connective tissue in which the fibers are impregnated with a form of calcium phosphate similar to hydroxyapatite.
3. the bones of the human skeleton.
n 4. a single element of the skeleton such as a rib or femur.

bone, alveolar

n the specialized bone structure that contains the alveoli or sockets of the teeth and supports the teeth.

bone, alveolar, architecture,

n the structural pattern of the alveolar bone and its subjacent latticework of supporting bone. The alveolar bone is thin and compact adjacent to the periodontal ligament. The trabecular bone connects and reinforces the individual alveoli. The architecture of a bone is the result of functional stimuli to that bone; the stimuli vary according to type, intensity, and duration.

bone, alveolar, metabolism,

n the metabolic activity occurring within alveolar bone, which is generally slower than that occurring within metaphyseal bone but more rapid than that of diaphyseal bone.

bone apposition,

n See bone deposition.

bone augmentation,

n a procedure used to build or enhance bone. It refers to either bone grafting or bone growing. Bone augmentation materials are classified as osseous, in which bone or bony substitutes are used to form new bone, or osseous conductive, in which these materials provide a platform for regeneration without taking part in actual bone formation.

bone, basal,

n the part of the mandible and maxilla from which the alveolar process develops.

bone, bundle,

n the bone forming the immediate bone attachment of the numerous bundles of collagen fibers of the periodontal ligament that have been incorporated into the bone.

bone bur,

n a drill designed to cut into bone.

bone, cadaver,

n bone that has been donated for medical purposes from one person to another; used especially in bone grafting procedures. See also allogenic and allografts.

bone calcium content,

n the amount of calcium stored in bone tissue. Plasma calcium is in constant exchange with the calcium of the extracellular fluid and bones. The parathyroid gland maintains the constancy of the calcium concentration in the plasma.

bone, cancellous, atrophy of disuse

n the wasting of bone tissue occurring with loss of function of a part (e.g., a tooth). The supporting bone assumes an osteoporotic nature, and the marrow remains fatty or hematopoietic.

bone cells,

n.pl the group includes osteoblasts, osteocytes, osteoclasts, and osteoprogenitor cells.

bone changes, mechanical factors,

n.pl the pressure and tension forces that play an important role in determining bone structure. Improperly controlled appliances can resorb bone faster than deposition can occur, causing mobile teeth and traumatic occlusion. Poor vascularity is a concomitant cause of undue pressure and tension and may inhibit repair and cause necrosis.

bone chips,

n.pl the small pieces of cancellous bone generally used to fill in bony defects and precipitate recalcification.

bone, compact,

n the hard, dense bone composing the outer cortical layer and consisting of periosteal bone, endosteal bone, and haversian systems.

bone defects, angular,

n.pl the usually localized anomalies that occur in the crestal bone as the result of both periodontal inflammation and occlusive trauma.

bone formation,

n the deposition of an organic mucopolysaccharide matrix (osteoid) that is subsequently mineralized with calcium salts. See also bone apposition and bone deposition.

bone graft, autogenous

n See graft, autogenous bone.

bone graft, donor site,

n See donor site.

bone graft, onlay,

n See graft, onlay bone.

n membrane bone forms directly from the mesenchyme, first as a thin, flattened, irregular bony plate or membrane in the dermis and gradually expanding at its margins and becoming thickened by the deposition of successive layers of additional bone on the inner and outer surfaces. See also bone, endochondral, formation.

bone, microscopic appearance of,

n the composition of bone tissue as viewed under a microscope. Microscopically, bone is composed of osteocytes embedded within lacunae in a calcified intercellular matrix. Extending from the lacunae are small canals called canaliculi, which communicate with canaliculi of adjacent lacunae. Through this system of canals, nutrient material reaches the osteocytes and provides avenues for the removal of waste products of metabolism. It is deposited in incremental layers (lamellae) around haversian canals, the lamellae toward the surface of the bone being more or less parallel to it.

bone mineral content, chemistry of,

n the hardness of bone results from its mineral content in the organic matrix. The minerals (commonly designated as bone salts) and the organic matrix make up the interstitial substance of bone.

Patient discussion about bone file, bone rasp.

Q. Is a bone tumor cancer? My son is 10 years old and his Doctor found a tumor on his bone in an x-ray he did to him. Is this cancer?

A. A bone tumor doesn't necessarily mean cancer. It could be a benign tumor and not a cancer one. Your son's doctor may then obtain a biopsy sample of the tumor. This involves taking a small sample of the tumor that can be examined in the laboratory to determine what kind of tumor it is. The biopsy can be obtained either through a small needle (needle biopsy) or through a small incision (incisional biopsy).

Q. is bone loss related to Arthritis?

A. It depends on the kind of arthritis. In some arthritic diseases there's local bone loss, and generalized bone loss (osteoporosis) may result from steroids used to treat arthritic diseases.

You may read more here:
www.nlm.nih.gov/medlineplus/osteoporosis.html

Q. I have constant pain on my feet more on my bones than anything,do I have arthritis? I do already have plantar fascictis

A. Chronic arthritis is a disease of the elderly and it isn't common to suffer from it in young age, however joint pain or bone pain can be caused by several other reasons, that might not be chronic, such as an infection, excessive physical activity or such. You should see a doctor to evaluate the pain and joint movement. He/ she might send you to do an x-ray to see if there's something they can see that is wrong with the joint or bone (dislocation or fracture).
