• Motor neuron: Transmits signals from the CNS to the rest of the body such as signaling muscles or glands to respond. • Interneurons: Transmit signals between neurons ▪ Neurons consist of three basic parts: • Cell body: Contains the nucleus of the of the neuron. • Axon: Transmits impulses away from cell body. It’s insulated with oligodendrocytes & myelin sheaths with gaps (nodes of Ranvier). Axon terminates at the synapse. • Dendrites: Receive impulses from sensory recept...
