GENERAL HISTOLOGY

Detailed explanation-1: -Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells.

Detailed explanation-2: -Osteocytes, the cells residing within the bone matrix and comprising 90% to 95% of the all bone cells, have long been considered quiescent bystander cells compared to the osteoblasts and osteoclasts whose activities cause bone gain and loss, and whose dysfunction lead to growth defects and osteoporosis.

Detailed explanation-3: -Osteocytes are cells lying within the bone itself and are ‘entrapped’ osteoblasts. They are post-proliferative, representing the most mature differentiation state of osteoblast lineage.

Detailed explanation-4: -The first type of bone formed developmentally is primary or woven bone (immature). This immature bone is later replaced by secondary or lamellar bone (mature).
