epiphyseal plate

ex 456

during childhood and adolescence where do long bones grow

epiphyseal plate

where is epiphyseal plate located

between diaphysis and each epiphysis

what undergoes a process within these plates

resting cartilage

what does the process do the testing cartilage

ends in ossification into bone

when does this process of ossification stop

beginning at puberty

when the cartilage tissue becomes plated and ossified what does it now become

epiphyseal line

epiphysis

spongy bone

what does zone of resting cartilage represent

hyaline cartilage

what does zone of resting cartilage do

secures epiphysis to the plate

what happens to chrondocytes during zone of testing cartilage

they begin to divide fast to secrete matrix

what are chrondocytes compared to while in zone of proliferation

stack of coins

what happens in zone of hypertrophic cartilage

chrondocytes stop driving to enlarge

what happens in zone of calcified cartilage

minerals are deposited in matrix

what happens to chrondocytes in zone of calcified cartilage

they are sealed and killed off

what is zone of ossification invaded by

blood vessels and osteoblasts

what happens to the bony matrix in zone of ossification

it is deposited on calcified cartilage
