2types of bone tissue
compact
spongy
3long bone structures (DEAEMPE)
diaphysis
epiphysis
articular cartilage
epiphyseal plate
medullar cavity
periosteum
endosteum
4– shaft
– compact bone
tissue (on outside)
diaphysis
5– ends
– spongy bone tissue
epiphysis
6- covers epiphyses
- reduces friction
articular cage
7– site of growth
– between diaphysis and epiphysis
epiphyseal plate
8– center of diaphysis
– red or yellow marrow
medullar cavity
9membrane around bone’s outer surface
periosteum
10membrane that lines medullary cavity
endosteum
11location of compact bone tissue
outer part of diaphysis and thinner surfaces of other bones
12- structural unit of compactbone
osteon
13lamella, lacunae, canaliculus, central canal, osteocytes
osteon
14sings of bone matrix
lamella
15spaces between lamella
lacunae
16tiny canals, transport nutrients and remove waste
canaliculus
17center of osteon, contains blood vessels
central canal
18cancellous bone, no osteons
spongy bone tissue
19location of spongy bone tissue
epiphyses of long bones and center of other bones
20interconnecting rods, spaces contain marrow
trabeculae
