What part of the long bone is the Metaphysis?
Middle portion between epiphysis and diaphysis
What part of the long bone is the growth plate located?

What are the 4 layers of bone from outside to inside?
- Periosteum
- Compact bones
- Cancellous / spongy bone

What is the periosteum?
Membranous tissue that covers outside of bone and is important for growing and repairing bones

Dense material used to create the hard structure of the skeleton
What are cancellous/spongy bones? (Bone layers)
Full open sections called pores that are filled with marrow, nerves and blood vessels that carry nutrients in and out of bone
What is marrow? (Bone layers)
