Mielina

• Información general

Definición:

Es una capa aislante que se forma alrededor de los nervios, incluyendo los que se encuentran en el cerebro y la médula espinal, y está compuesta de proteína y sustancias grasas. El propósito de la vaina de mielina es permitir la transmisión rápida y eficiente de impulsos a lo largo de las neuronas. Si la mielina se daña, los impulsos se interrumpen, lo cual puede causar enfermedades como la esclerosis múltiple.
