Skeleton system Flashcards
Osteocyte

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

When the blood levels of calcium are low, osteoclasts release calcium from bone under the control of parathyroid hormone
