| | Skeletal System Information on Healthline |
 | | The skeletal system is a living, dynamic, bony framework of the body, with networks of infiltrating blood vessels. |
 | | The human skeletal system is divided into two main groups: the axial skeleton and the appendicular skeleton. |
 | | Blood vessel, lymph vessels, and nerves run through the center of the tube, called the Haversian canal, and are surrounded by layers of bone, called lamellae, which house the osteocytes. |
