PY - 2015 T2 - Goldfrank's Toxicologic Emergencies, 10e AB - The central nervous system (CNS) coordinates responses to the fluctuating metabolic requirements of the body and modulates behavior, memory, and higher levels of thinking. These functions require a diversity of cells: astrocytes, neurons, ependymal cells, and vascular endothelial cells. Disruption or death of any one cell type can cause critical changes in the function or viability of another. This cellular interdependence, along with the high metabolic demands of the CNS, makes neurons especially vulnerable to injury from both endogenous neurotoxins and xenobiotics. Endogenous neurotoxins, such as the metals iron, copper, and manganese, are substances that may be critical to CNS function but are harmful when their penetration into the CNS is poorly controlled.
