Spinal nerve. Coloured scanning electron micrograph (SEM) of a spinal nerve,which has been freeze-fractured to reveal the bundle of nerve fibres (axons,green and blue) inside. The axons are sheathed in myelin,a fatty insulating substance that increases the speed that nerve impulses are conducted. In the centre of the nerve is a blood vessel (purple) containing biconcave red blood cells. Magnification: 100x at 10cm across | |
