Nerve demyelination. Coloured transmission electron micrograph (TEM) of a section through a Schwann cell and a nerve fibre, showing the early collapse of its myelin sheath. Myelin (red) is an insulating fatty layer that surrounds the nerve fibre (axon, orange), increasing the speed at which nerve impulses travel. It is formed when a Schwann cell (green) wraps around the fibre, depositing layers of myelin between each coil. Demyelination occurs in nerve disorders such as multiple sclerosis (MS). Patches (lesions) of myelin sheath are destroyed and nerve function is impaired. Magnification: x3800 when printed 10 centimetres wide.

High cholesterol levels. Computer artwork balls of cholesterol in a blood vessel. Cholesterol is a lipid, a fat-like substance. High blood levels of LDL (low-density lipoprotein) cholesterol compared to HDL (high-density lipoprotein) cholesterol are thought to raise the risk of atherosclerosis, the build-up of fatty deposits on artery walls. This is a major cause of heart attack and stroke.
