A connective tissue membrane that covers the outside of the bones

A connective tissue membrane that lines the medullary cavity

A tiny hole that the blood vessel threads through

Adipose tissue found within the medullary cavity

Allows newly formed blood to exit the bone and enter the bloodstream; allows the bone tissue to receive nutrients, oxygen, and hormones

Found inside the spongy tissue at the ends of our bones

Full of bone-growing cells (osteoblasts) that allow our bones to grow in width
