Lacunae
空白
Osteocytes are located within the chambers called lacunae
Lamellae
In the compact bone, lacunae lie in the concentric circles of the matrix called Lamellae.
Lamellae are disposed around a cylindrical tube called a central canal.
Central canals contain the blood vessels and nerves.
Canaliculi
Osteocytes pass nutrients and gases through tiny canals called canaliculi
perforating canal
Central canals of adjacent osteons are interconnected by transverse perforating canals
