Osteogenic cells

undergo the process of mitosis and form osteoblasts


form bone matrix by secreting collagen; no mitosis


Mature cells, develop from osteoblasts, control day-to-day activities (each occupies a lacuna, a pocket sandwiched between layers of matrix


remodeling: when blood calcium level is low, these cells break down bone to release calcium and phosphorous

Bone Lining Cells

made from osteoblasts along the surface of most bones in adults, regulates the movement of calcium and phosphate into and out of the bone


the formation of blood cells in the living body (especially in the bone marrow)

Hyaline Cartilage

most common, tips of bones at joints, soft part of the nose, supporting rings of the trachea. Prominent in early development

Elastic Cartilage

matrix packed with elastic fibers, making it more flexible. found in external ear and epiglottis of larynx


few lacunae and chondrocytes. matrix packed with collagen fibers. found in the intervertebral disks, knee menisci and pubic symphisys


Tough, tight-fitting membrane that coves a bone's surface and contains blood vessels that transport nutrients into the bone


means "little lake," small pockets situated between lamellae containing osteocytes of compact bone.

Haversian Canal

longitudinal canal carrying blood vessels and nerves


basic functional unit of the bone

Spongy Bone

Type of bone that is light and has pores found near joints


vascular membrane that lines the inner surface of long bones


concentric, ring-linke arrangement of bone tissue

Perforating Canal

connect central canals and hold blood vessels and nerves

Compact Bone

tightly solid, strong bone tissue resistant to bending


the main section of a long bone


the end of a long bone

Medullary Cavity

cavity within the shaft of the long bones filled with bone marrow

Articular Cartilage

thin hyaline cartilage layer that covers epiphyses of bones in synovial joints


small canals radiating in all directions from launae, allowing for communication between osteocytes

Epiphyseal Plate

cartilage plate between epiphysis and diaphysis and allows growth to occur


sponge like apperance of the cancellous bone

Cancellous Bone

bone connecting trabeculae; also known as spongy bone


the growing part of a long bone between the diaphysis and the epiphysis

Spinal Stenosis

Narrowing of the neural canal or nerve root canals in the lumbar spine.


an inherited skeletal disorder beginning before birth

Juvenile Rheumatoid Arthritis

a form of rheumatoid arthritis that affects children

Ankylosing spondylitis

a form of arthritis thats effects the spine and adjaciant structures


malignant bone tumor


abnormal loss of bony tissue resulting in fragile porous bones attributable to a lack of calcium

Disc Herniation

rupture of the soft tissue that separates two vertebral bones into the spinal canal


an abnormal lateral curve to the vertebral column
