GENERAL HISTOLOGY

Detailed explanation-1: -By means of these canaliculi, nutrients and waste products are exchanged to maintain the viability of the osteocyte. Osteocytes are the most abundant type of cell in mature bone tissue. They also are long-lived, surviving as long as the bone they occupy exists.

Detailed explanation-2: -The movement of bone fluid from the region of the bone vasculature through the canaliculi and the lacunae of the surrounding mineralized tissue accomplishes three important tasks. First, it transports nutrients to the osteocytes in the lacunae buried in the mineralized matrix.

Detailed explanation-3: -Osteocytes receive nutrients and eliminate wastes through blood vessels in the compact bone. Blood vessels in the periosteum and endosteum supply blood to blood vessels in the central canals. Nutrients leave the blood vessels of the central canals and diffuse to the osteocytes through the canaliculi.

Detailed explanation-4: -Osteocytes are the longest living bone cell, making up 90–95% of cells in bone tissue in contrast to osteoclasts and osteoblasts making up  5% (40). Osteocytes form when osteoblasts become buried in the mineral matrix of bone and develop distinct features.
