Skeletal System

2.  Diaphysis - long central shaft
 Epiphysis - rounded ends of long bones
 Epiphyseal Plates - Plates of cartilage,
known as growth plates which allow
growth in length childhood
 Cancellous bone - where blood cells are made
 Compact bone –gives strength to the hollow part
of the bone
 Periosteum – ligaments and tendons attach to the
periosteum
 Marrow cavity - where white blood cells are made

3. Bone Growth
In fetus most of skeleton is cartilage
As fetus develops minerals are used and bones become harder and less
flexible
This is ossification and continues until we are adults
Bones keep growing up to age of 25
Growth occurs at epiphyseal plate and two ends of bone push away
from each other
Bone continues to be broken down and replaced by osteoclasts and
osteoblasts
