Types of bone cells

Question 1

what are osteoblasts

Answer 1

BLASTS= BUILD

these are bone building cells which lay down calcium, matrix and fibres

Question 2

WHERE ARE OSTEOBLASTS LOCATED

Answer 2

at bone surfaces
ossification sites
at sites of fractures
in the metaphysis (regions of long bone where ossiffication occures)

Question 3

what is the function of the osteoblatst

Answer 3

they make collagen to form bone matrixs and they control the calcification and mineralisation of bones

Question 4

what is the bone matrix

Answer 4

bone matrix consists of collagen fibres
they have a high inorganic salt content which make them hard

these inorganic salts are deposited between these collagen fibres

Question 5

what are osteoclasts

Answer 5

these are large cells with several nuclei
they work to break down the bone by absorption for remodelling

their ruffled border releases acid and enzymes which deigest the mineral and protein contents of the bone

ythey are found in the periosteum and endosteum

Question 6

what are osteocytes

Answer 6

these are mature bone cells formed when osteoblasts are no longer producing collagen

they are surrounded by bone matrixs produced by osteoblasts

they are responsible for nutrients and waste
