Science Fun of the Week

(October 21st, 2016) Get ready for your weekly dose of science fun. Today: The happy, little devil in all of us.

From the Ihearthisto blog: "In this case, the devil is in the medullary cavity of the diaphysis of a proximal phalanx. And he’s making work for idle osteons. This devil is not an osteon (which is how cortical bone around the outside of a bone is organised) but a trabecula, which is how the spongy bone within the diaphysis of a long bone is organised. His peepers are mature bone cells (osteocytes) residing in white lacunae. His smile is a bony lamellar. His horns are remnants of the endosteum and some of the hematopoietic cells (blood forming cells) that occupy the marrow cavity (white space in this image)."
