excitotoxicity
eccitotossicità

he descending sympathetic tracts are disrupted most commonly from associated fracture or dislocation of vertebrae in the cervical or upper thoracic spine. primary spinal cord injury occurs within minutes of the initial insult. primary injury is direct damage to the axons and neural membranes in the intermediolateral nucleus, lateral grey mater, and anterior root that lead to disrupted sympathetic tone. secondary spinal cord injury occurs hours to days after the initial insult. secondary injury is a result of vascular insult, electrolyte shifts, and edema that lead to progressive central hemorrhagic necrosis of grey matter at the injury site. at a cellular level, there is excitotoxicity from nmda accumulation, improper homeostasis of electrolytes, mitochondrial injury, and reperfusion injury which all lead to controlled and uncontrolled apoptosis. neurogenic shock is a combination of both primary and secondary injuries that lead to loss of sympathetic tone and thus unopposed parasympathetic response driven by the vagus nerve. consequently, patients suffer from instability in blood pre
