Neurons – The cells in the nervous system that receive and transmit information. 5. Sensory Neurons – Cells that carry environmental messages toward the spinal cord and brain. 6. Interneurons – Cells that transfer information from one neuron to another; interneurons make no direct contact with the outside world. 7. Motor Neurons – Cells that carry information away from the central nervous system to the muscles and glands that directly produce behavior. 8. Glial Cells – Cells that fill in space between neuron, remove waste, or help neurons to communicate efficiently. 9. Myelin Sheath – An insulating material that protects the axon and helps to speed up neural transmission. 10. Reflexes – Largely automatic body reactions – such as knee jerk – that are controlled primarily by spinal cord pathways. 11. Dendrites – the fibers that extend outward from a neuron and receive information from other neurons. 12. Soma – The cell body of a neuron. 13.

Terminal Buttons – The tiny swellings at the end of the axon that contain chemicals important to neural transmission. 15. Synapse – The small gap between the terminal buttons of a neuron and the dendrite or cell body of another neuron. 16.
