Under circularly polarized light microscopy (a) (original magnification × 50), the transverse collagen fibers appear in yellow-orange, while the longitudinal ones appear in white-blue. The transverse collagen fibers are mainly associated to the lower flank of the threads. b Original magnification × 200. Bone appears mainly constituted by transverse collagen fibers. The presence of an osteon shows bone remodeling activity
