Answer:
The axon conducts messages away from the cell body. ... Interneurons are found only in the central nervous system where they connect ... This toxin causes the progressive relaxation of muscles, and can be fatal. ... In the sensory centers of the brain or in the spinal cord, the barrage of input is integrated and a response is ...Three types of neurons occur. Sensory neurons typically have a long dendrite and short axon, and carry messages from sensory receptors to the central nervous system. Motor neurons have a long axon and short dendrites and transmit messages from the central nervous system to the muscles (or to glands). Interneurons are found only in the central nervous system where they connect neuron to neuron.
