Spider venoms can be grouped into two broad categories: necrotic, and neurotoxic necrotic, or cytotoxic venoms, are those which cause cell and tissue damage after envenomation this can lead to the appearance of inflammation, lesions, and blisters neurotoxic venoms, on the other hand, exert their effects on the nervous system, and interfere with signalling between [.
