ch 6 Flashcards
tissues present in bone
blood, marrow, cartilage, adipose tissue, nervous tissue, fibrous CT
ostelology
study of bone
mineralization
process of hardening
organic matrix
collagen and large glycoprotines
inorganic matrix
hydroxyapatite (85%)
calcium carbonate (10%)
other
feature of connective tissue (matrix)
more extracellular matrix
red bone marrow
hemopoietic tissue
younger
in most of younger kids
yellow bone marrow
adults
fatty
bone classification (6)
flat, long, short, irregular, sesamoid, sutural (wormian)
flat bone
thin, usually curved
ex: rib
long bone
rigid levers of movement
ex humerus
short
glide within joints
ex carpal
irregular
complex shape
ex. vertebrae
sesamoid
develop in a tendon
patella
sutural (wormian)
bn flat bones of skull, like the little ridges
structure of long bone (9)
periosteum, diaphysis, epiphysis, medullary cavity, endosteum, articular cartilage , epiphyseal plate, epiphyseal line
periosteum
fibrous connective tissue sheath
diaphysis
shaft
medullary cavity
marrow cavity
endosteum
thin layer of reticular tissue lining medullary cavity
articular cartilage
hayline cartilage
epiphyseal plate
growth plate, hylaine
epihyseal plate
growth plate
hyaline cartilage
epihyseal line
Remnant of the epiphyseal plate
Nutrient foramen
hole for blood vessels and nerves
medulla-
inside
cortex-
outside
flat bone is made of
spongy bone bn compact bone (diploe)
osteogenic (osteoprogenitor)
bone stem cells
osteoblast
bone forming cells
osteocyte
mature bone cell
osteoclast
bone dissolving macropphage
osteocytes have
filopodia (dendrites) with gap junctions at ends
central canal
Contains blood vessels and nerves
(compact bone)
