(putting the puzzle together) Motor sends commands to your muscles that make you do things. Soma (the place where information is processed and summed up) Axon (the highway that the signal travels on which is passed to another neuron is the soma allows said message to be passed) Myelin sheath (fatty layer that covers the axon. Neurons with these can react faster than ones without. ) Axon hillok (the part of the soma that calculates whether or not the message should be sent. Terminal buttons (connect to the dendrites of another neuron) Synapse (the space between the button of one axon and another neuron"s dendrite. Excitatory tells you yes, pass on the message. Inhibitory tells you no, don"t pass on the message.
