EM 218 Osteocyte

Osteocyte

Scanning electron micrograph (SEM) os an osteocyte trapped in a lacunae.

  • - oblong spaces found between lamellae that contain a single osteocyte.
  • (purple) - reside in a lacunae and extend long cytoplasmic processes to other osteocytes.
  • - small canals between lacunae that contain cytoplasmic processes between adjacent osteocytes.
  • (tan) - unmineralized collagen surrounding an osteocyte.
  • (blue) - calcified bone matrix. (A bone fragment has dropped into the lacunae to the right of the osteocyte.)
