Description
Compact bone. Polarised light micrograph of a transverse section through compact bone tissue, showing Haversian canals (circular regions). The concentric rings surrounding the Haversian canals are called lamellae. The canals run along the long skeletal bones, and contain blood vessels, lymphatic vessels, and nerves. The lamellae are made of compacted collagen fibres and minerals produced by bone-forming cells that are called osteoblasts. The osteoblasts become trapped in the bone matrix at sites called lacunae (small dark spots spaced throughout). Magnification: x36 when printed at 10 centimetres across.
