A
• Outside covering of the

• It is a layer of fibrous
connective tissue
4
Q
What is the Sharpey’s fibers
A
• Secures periosteum to underlying bone
5
Q
What is the Arteries
A
• Supply bone cells with nutrients
6
Q
What is the Articular cartilage
A
- Covers the external surface of the epiphyses
- Made of hyaline cartilage
- Decreases friction at joint surfaces
7
Q
What is the Epiphyseal plate
A
• Flat plate of hyaline cartilage seen in young, growing bone.
8
Q
What is the Epiphyseal line
A
