What Does the Periosteum Supply Bone Cells With

The outer layer of the periosteum is mostly made of elastic fibrous material, such as collagen. It also contains blood vessels and nerves. The blood vessels of the periosteum contribute to the blood supply of the body’s bones. They can pass into the dense and compact layer of bone tissue below, called the bone cortex.

What does the periosteum produce?

By a process identical to membranous ossification the periosteum begins producing a thin peripheral layer of bone termed the bone bark.

What cells does the periosteum contain?

The periosteum consists of an outer “fibrous layer” and inner “cambium layer”. The fibrous layer contains fibroblasts while the cambium layer contains progenitor cells which develop into osteoblasts that are responsible for increasing bone width.
