Definition
| dense layer of connective tissue (membrane) that surrounds bone, protects bone, assists in fracture repair, helps nourish bone, serves as attachment point |
|
|
Term
|
Definition

|
Term
| medullary or marrow cavity |
|
Definition
| space within the diaphysis that contains fatty yellow bone marrow in adults |
|
|
Term
|
Definition
| thin membrane that lines medullary cavity. contains a single layer of bone forming cells |
|
|
Term
|
Definition
| large artery that goes through nutrient foramen to bring nutrients to an area |
|
|
Term
osteogenic cells
genic=producing |
|
Definition
| unspecialized stem cells derived from mesenchyme, the tissue from which all connective tissue forms. the only bone cells that undergo cell division |
|
|
Term
osteoblasts
blasts= buds or sprouts |
|
Definition
| bone building cells. synthesize and secrete collagen fibers and other organic compounds needed to build the matrix of bone tissue |
|
|
Term
|
Definition
| mature bone cells. retired. do not produce bone tissue |
|
|
Term
|
Definition
| huge cells derived from the fusion of as many as 50 monocytes and are concentrated in the endosteum |
|
|
Term
Hemopoiesis
hemo- blood
poiesis- making |
|
Definition
| the process of making blood |
|
|
Term
|
Definition
| connective tissue that produces red blood cells, white blood cells, and platelets in a process called hemopoiesis |
|
|
Term
|
Definition
| consists mainly of adipose cells (fat cells) which store triglycerides and a few blood cells |
|
|
Term
|
Definition
| forms external layer of all bones, and makes up the bulk of the diaphyses of long bones. provides protection and support |
|
|
Term
|
Definition
| does not contain osteons. makes up most of the tissue of short, flat, and irregular shaped bones. also forms epiphyses of long bones |
|
|
Term
trabeculae
= little beams |
|
Definition
| irregular latticework of thin columns of bones |
|
|
Term
|
Definition
| matrix deposited on cartilage surface. growth in thickness |
|
|
Term
|
Definition
| growth in length. continual cell division of chondrocytes |
|
|
Term
|
Definition
| x rays pass through body to produce an image on x-ray sensitive film. produces clear image of bony or dense structures |
|
|
Term
|
Definition
| x-ray beam traces an arc at multiple angles of body. shows soft tissues and organs in more detail. differing tissue densities show up as differing shades of gray |
|
|
Term
| MRI (Magnetic Resonance Imaging) |
|
Definition
| body exposed to high energy magnetic field. causes protons in body fluids and tissues to arrange themselves in relation to a field. Produces 2D or 3D blueprint of cellular chemistry. relatively safe. can't be used if metal in the body. shows fine detail of tissues, but not bones |
|
|
Term
|
Definition
| high frequency sound waves reflect off body tissues to produce image. (sonogram for pregnancy) safe, no chemicals, noninvasive |
|
|
Term
| PET (Positron Emission Tomography) |
|
Definition
| substance that emits positron is put into the body, taken up by tissues, which produces gamma rays that are detected by gamma cameras. used to study physiology |
|
|
Term
|
Definition
| diagonistic procedure where a small amount of radioactive tracer is injected and absorbed by bone. scanned to find radiation emitted from bones to find bone abnormalities |
