Osteocytes originate from osteoblasts that have migrated into and become trapped and surrounded by bone matrix that they themselves produce. The spaces they occupy are known as lacunae.
Haversion system arrangement of compact bone consisting of osteocytes and matrix in cylinders of bone surrounding central haversion canals.
Helicotrema a tiny hole where compartments communicate at the tip of the cochlea.
Heparin a substance that prevents clotting under normal conditions.
