2. ď Diaphysis - long central shaft
ď Epiphysis - rounded ends of long bones
ď Epiphyseal Plates - Plates of cartilage,
known as growth plates which allow
growth in length childhood
ď Cancellous bone - where blood cells are made
ď Compact bone âgives strength to the hollow part
of the bone
ď Periosteum â ligaments and tendons attach to the
periosteum
ď Marrow cavity - where white blood cells are made
3. Bone Growth
ďIn fetus most of skeleton is cartilage
ďAs fetus develops minerals are used and bones become harder and less
flexible
ďThis is ossification and continues until we are adults
ďBones keep growing up to age of 25
ďGrowth occurs at epiphyseal plate and two ends of bone push away
from each other
ďBone continues to be broken down and replaced by osteoclasts and
osteoblasts
