Macroscopic structure of long bone Flashcards
1
Q
Diaphysis
A
Long, main shaft
2
Q
Epiphysis
A
Ends of bone (proximal and distal)
3
Q
Metaphysis
A
Between diaphysis and epiphysis - where bone growth occurs
4
Q
Articular cartilage
A
Thin layer of hyaline cartilage covering epiphysis (where an articular occurs)
> reduces friction and absorbs shock

5
Q
Periosteum
A
Tough connective tissue layer, surrounds bone surface
Growth in thickness, attachment point of ligaments/tendons
6
Q
Medullary cavity
A
Hollow part in diaphysis where bone marrow
Minimises weight of bone and provides strength
7
Q
Endosteum
A
Thin membrane lining medullary cavity
single layer of osteoprogenitor cells and connective tissue
