Punción lumbar

El líquido cefalorraquídeo (LCR) es un líquido transparente que circula en el espacio que rodea la médula espinal y el cerebro. El LCR protege al cerebro y a la médula espinal de lesiones actuando como un cojín. El LCR generalmente se obtiene a través de una punción lumbar (punción espinal). Para realizar este procedimiento se inserta una aguja generalmente entre la tercera y cuarta vértebra lumbar y se extrae líquido para ser examinado.Punción lumbar
