four.
The four main layers of bones are the periosteum (outer layer), compact bone (dense and hard layer), spongy bone (porous inner layer), and bone marrow (innermost layer responsible for blood cell production).
There are 4 layers of a bone the periosteum , compact bone , spongy bone or cancellus , and bone marrow.
the three layers are.... compact bone spongy bone bone marrow
Osteons, the structural units of compact bone, grow from the inside out. They develop through a process called appositional growth, where new layers of bone tissue are added to the outer surface of existing bone. As osteoblasts create new bone matrix, the central canal and surrounding layers expand, allowing for the growth of the osteon outward. This process helps maintain the strength and integrity of the bone as it adapts to mechanical stresses.
The three layers within a bone are periosteum, compact bone, and yellow marrow.

Compact bone tissue is arranged in concentric layers called lamellae around a central canal that contains blood vessels and nerves. These layers give compact bone its strength and resilience, helping to support the body and protect vital organs.
The main difference between the outside and inside of bone is; the inside of a bone is bone mallow, whereas the outside of a bone is covered by flesh.
