GENERAL HISTOLOGY

Detailed explanation-1: -The bone matrix eventually grows to surround osteoblasts and the bone material becomes calcified. Once surrounded and trapped, the osteoblast becomes a mature bone cell referred to as an osteocyte.

Detailed explanation-2: -Osteoblasts migrate to the membranes and deposit bony matrix around themselves. When the osteoblasts are surrounded by matrix they are called osteocytes.

Detailed explanation-3: -In most cases, osteoblasts are separated from the region of calcification by a layer of the osteoid matrix they secrete. Occasionally, though, osteoblasts become trapped in the calcified matrix and become osteocytes-bone cells.
