His parents were both heterozygous for hyperthermia and had the recessive gene. (hope this helps)
In neurogenic shock, the characteristic mechanism is the reduction of sympathetic outflow from the brainstem leading to the decreased in the blood vessel tone and eventually vasodilation. In the presence of vasodilation, there will be decreased blood pressure and eventually shock. Since there is reduced sympathetic outflow, there will also be a decreased heart rate, warm skin (from the vasodilation), and dry skin (from the reduced cholinergic stimulation of the sweat glands).
The answer is c. Hope this helps you
