Composition and Formation of Myelin Sheath Molecular Neurobiology Myelin may be made by different cell types‚ varies in chemical composition and configuration‚ but performs the same insulating function. Myelin is about 40% water; the dry mass of myelin is about 70 - 85% lipids and about 15 - 30% proteins. Some of the proteins that make up myelin are myelin basic protein (MBP)‚ myelin oligodendrocyte glycoprotein (MOG)‚ and proteolipid protein (PLP). The primary lipid of myelin is a glycolipid

The nervous system is one of the most important systems in the body. The nervous system helps to keep the human body in balance. There are several important parts of the nervous system; the brain‚ spinal cord‚ and nerves. Each part of the nervous system has different jobs. There are two main parts of the nervous system peripheral and central. The peripheral nervous system is a collection of peripheral nerves‚ ganglia and specialized sensory structures that‚ as a unit‚ carries sensory and motor information

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming
