Today Hank explains the skeletal system and why astronauts Scott Kelly and Mikhail Kornienko are out in space studying it. He talks about the anatomy of the skeletal system, including the flat, short, and irregular bones, and their individual arrangements of compact and spongy bone. He'll also cover the microanatomy of bones, particularly the osteons and their inner lamella. And finally he will introduce the process of bone remodeling, which is carried out by crews of osteocytes, osteoblasts, and osteoclasts.nnTable of ContentsnAnatomy of the Skeletal System 2:33nFlat, Short, and Irregular Bones 3:11nArrangements of Compact and Spongy Bone 4:22nOsteons and Their Inner Lamella 5:05nBone Remodeling 7:28nOsteocytes, Osteoblasts, and Osteoclasts 6:03nn***nnCrash Course is now on Patreon!
