If a paraplegic gets a mosquito bite on his leg, does the area around the bite swell up? Does swelling require a brain signal to tell the blood to rush to the area, and if it does, does the signal get through in this case?

i do noottttttttt know... possibly no because you will not feel the bite...so your brain does not know it is there.....but it cant send signals to there saying anything about the blood either.....soooo

No, the brain does no thave send a signal to make the swelling happen the swelling is a reaction to chemicals in the bite and bacteria.

This is a case of local inflammation with release of inflammatory compounds like histamine etc. There is no higher input. If that was the case then, in theory, one would be able to control the degree and extend of inflammation after a bite, sprain or injury.

This is an interesting question.

There's a wide variety of chemical communications constantly occurring throughout your body that don't involve the central nervous system. Blood also clots as a local, autonomous reaction involving chemical "communications". If not, and a mosquito bit you while sleeping, you'd bleed to death.

Otherwise, it would be like having to get White House approval for you to open a window on a hot day, or to buy more breakfast cereal because you just finished the last box. (Maybe in a communist country, but not a free society.)
