The Brain - Gray matter in the brain controls sensory perception, muscle control, emotions, hearing, memory etc. So gray matter in the brain is obviously influenced in a very special way by Z1 (zombie virus). So even with the loss of its higher-brain functions the fact that it can still move and respond etc renew its 'warranty' right? Wrong.Very simple question, what do you think that gave zombies ability to move and react ?
Take for instance a Brown Recluse Spider's venom traveling along a limb through a vein or artery - the resulting tissue mortification can affect an area as large as several inches and in extreme cases require excising of the wound. When necrosis of tissues is a possibility in a healthy living organism, the same case holds true with a dead organism with base functions. Keep in mind, Z1 is still a pathogen and not a solution.
