Anatomy Chapter 5
epiphyseal plate
a flat plate of hyaline cartilage
osteon
a system of interconnecting canals in the microscopic structure of adult compact bone; unit of bone
osseous tissue
another name for bone tissues is the major structural and supportive connective tissue of the body. Bone tissue forms the rigid part of the bones that make up the skeleton.
epiphyses
are the ends of the long bone
ossification
bone formation when bones develop using hyaline cartilage structures as their "models"
articular cartilage
covers epiphysis's external surface
periosteum
diaphysis is covered and protected by a fibrous connective tissue called this
Haversian system
each complex consisting of central canal and matrix rings is called this
hematopoiesis
formation of blood cells
osteoclasts
giant bone-destroying cells in bones
osteoblasts
hyaline cartilage model is completely covered with bone matrix by bone-forming cells called this
epiphyseal line
in adult bones - a thin line of bony tissue spanning the epiphysis that looks different from rest of bone in that area
yellow marrow/medullary cavity
in adults - cavity of shaft is primarily a storage area for adipose tissue
spongy bone
is composed of small needlelike pieces of bone and lots of open space
compact bone
is dense and looks smooth and homogeneous
calcification
is the accumulation of calcium salts in a body tissue
endosteum
is the membrane lining the medullary cavity
metaphysis
is the region where the diaphysis joins the epiphysis and is the site of the epiphyseal plate
osteocytes
mature bone cells
concentric lamellae
one of the tubular layers of bone surrounding the central canal in an osteon
lacunae
osteocytes are found within the matrix in tiny cavities called this
trabeculae
plates with irregular interconnected spaces in spongy bone
diaphysis
shaft
perforating (Volksmann's) canals
the communication pathway from the outside of the bone to its interior is completed by this
central (Haversian) canals
the lacunae are arranged in concentric circles called lamellae around ________ ________.
canalicuili
tiny canals
