While smooth nerve fibers are common to invertebrates, for example, the giant axon of the squid (Hodgkin & Huxley, 1952), myelinated nerve fibers are widely found in vertebrates. A myelinated fiber is mainly composed of a...

Myelinization A developmental process whereby a protective fatty material wraps around nerve cells. Myelinization is a gradual developmental process whereby a protective, fatty material called myelin wraps around nerve cells in the peripheral and...

The myelin sheath is a fatty white covering which is wrapped around nerve fibers (axons) throughout the body, brain, and spinal cord. This covering is composed of the membranes of one of two different types of specialized cells. In the central nervous...

Myelin is the fatty substance that provides AXON insulation in the nervous system. In the CENTRAL NERVOUS SYSTEM myelin is provided by OLIGODENDROGLIA; in the PERIPHERAL NERVOUS SYSTEM it is supplied by SCHWANN CELLS. In both cases, cell processes wrap...

Myelin is an electrically-insulating phospholipid layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons, whereas oligodendrocytes supply it to those of the central...

A major effort is under way in medical research circles to shave years off the time it takes for discoveries by scientists to be converted into treatments for patients.A small number of nonprofit organizations have stepped in as middlemen to bridge what they say is...
