If the toxin is affecting dizziness, nausea, and muscle cramping, the toxin's most likely mode of action, or system transmission, is neuro-muscular. This can be determined by the affect the toxin has on the neurological system, as demonstrated by the symptom of dizziness, and the muscular system as demonstrated with the muscle cramping. The nausea can be related to both the muscular system and the neurological symptoms, as presented.
