Abstract
In ultrathin sections of bone specimens observed in the electron microscope, many apatite microcrystals having a plate-like habit are clearly visible, besides the well-known needleshaped forms. Stereoscopic views demonstrate that the needle-like microcrystals are actually the edge view of small, thin platelets.
Résumé
L'étude morphologique du minéral osseux au microscope électronique montre plusieurs microcristaux en forme de minces plaques, à côté des bien connues petites aiguilles. Par la méthode stéréoscopique, on peut démontrer que les petites aiguilles sont en effet des plaquettes vues selon la direction de la moindre épaisseur.
Zusammenfassung
Die morphologische Untersuchung von Knochenmineral am Elektronemikroskop zeigt mehrere Mikrokristalle in Form von dünnen Plättchen, neben den bereits bekannten kleinen Nadeln. Mittels der stereoskopischen Methode kann nachgewiesen werden, daß es sich bei den kleinen nadelförmigen Kristallen in Wirklichkeit um Kantansichten von Plättchen handelt.
