Document Summary
These arteries provide better nutrition to perinotochordal cells nearby o perinotochordal cells near the arteries grow larger and become vertebral bodies (yellow) o less nourished parts in between become discs (green) o notochord is squeezed into the zone between the developing vertebral bodies. Sclerotome cells migrate o perinotochordal sheath (centrum) o neural arch o costal element. Paired chrondrofication (formation of cartilage) centres appear o centrum o neural arch o costal. Ventres of ossification appear o centrum (unpaired) (green) o neural arches o costal elements. Secondary ossification centres appear (allows in increase in height) o tip of spinous process o tip of transverse process o ring apophysis. Locomotive strategies: o undulating o sprawling quadruped o erect quadruped o bipedal o arboreal. Symphysis joint: o cartilage end plate o annular apophysis (epiphyseal ring) o annulus fibrosus with alternating layers o nucleus pulposus. Posterior: o dynamic o control of direction of motion o neural arch.
