Image of bone remodeling: Scanning electron microscope images showing details of bone microanatomy. Scale bars, 100 mm. (a) Bone-forming surfaces are relatively smooth, presenting collagen deposits by osteoblast cells. Image taken on the maxillary bone of the Devil’s Tower Neanderthal. (b) Resorption is identified as irregular surfaces carved by osteoclasts on the bone surface as they dissolve and remove bone matrix. Image taken from the maxillary bone of the SH hominin Cranium 16.
