pounding headache, blurred vision, sweating above the level of the lesion with flushing of the skin, nasal
congestion, nausea, piloerection caused by pilomotor spasm, and bradycardia (30-40 beats/min)

Stimulation of the carotid sinus -->vagus nerve -->sinoatrial (SA) node. The intact ANS reflexively
responds with an arteriolar spasm that increases blood pressure. Baroreceptors in the cerebral vessels,
the carotid sinus, and the aorta sense the HTN and stimulate the PNS. The heart rate decreases, but the
visceral and peripheral vessels do not dilate because efferent impulses cannot pass through the cord
