MICROANATOMY

Detailed explanation-1: -Periosteum and endosteum contain cells (osteoblasts, osteoclasts, and osteoprogenitor cells) required for bone development and remodeling of the bone. Understanding the histology of the endosteum and periosteum will help to decode the pathological conditions of bone.

Detailed explanation-2: -Your periosteum helps your bones grow and develop. Special cells called osteoprogenitors create osteoblasts (the cells that grow your bones). Babies and children whose bones are still growing and developing have lots of active osteoblasts in their periosteum.

Detailed explanation-3: -The periosteum is a complex structure composed of an outer fibrous layer that lends structural integrity and an inner cambium layer that possesses osteogenic potential. During growth and development it contributes to bone elongation and modeling, and when the bone is injured, participates in its recovery.

Detailed explanation-4: -Osteoblasts are bone-forming cells. They’re very important during the fetal and childhood phases of life when bone tissue is still developing. As a result, the inner layer of the periosteum is thick and rich in osteoblasts in the fetus and during early childhood.

Detailed explanation-5: -The inner layer of the periosteum contains osteoblasts (bone-producing cells) and is most prominent in fetal life and early childhood, when bone formation is at its peak.
