"Insects have a complex nervous system which incorporates a variety of internal physiological information as well as external sensory information. As in the case of vertebrates, the basic component is the neuron or nerve cell. This is made up of a dendrite with two projections that receive stimuli and an axon, which transmits information to another neuron or organ, like a muscle. As with vertebrates, chemicals (neurotransmitters such as acetylcholine and dopamine) are releas… " - Sensory organ of insect
