Document Summary
Central canal - channel that houses blood vessels and nerves that supply the bone. Surround central canal, rings of bone tissue called concentric lamellae. Canaliculi - small channels between central canal and lamellae. Osteocytes send small projections into canaliculi cell communication between osteocytes. Connect to so the blood vessels in central canal can exchange nutrients, gases, etc with the osteocytes via canaliculi. Lamellae = tissue that makes up osteon. Remnants of osteons that have been partially reabsorbed. Form vascular and nervous network between osteons. Know the overall approach studying bones and muscles in your lab. Review the axial skeleton and associated muscles. Introduce importance of bone markings (bones of the skull) Support and protect organs of head, neck and trunk. The bones that connect the bones of skull are sutures. The effect produced by contraction of a muscle. Muscles often act together to control movement and stability of a joint. Flexion - decreases angle of a joint.
