Document Summary
Chapter 3: biology and behavior: define and describe the functions of the nervous system. Glial cells hold neurons together and help them communicate with one another: name and describe the features of neurons that allow them to communicate with one another. Communication between cells can occur when these fibers are close to other neurons. The interweaving of these fibers with fibers from other neurons allows each neuron to thousands of other neurons: define neurotransmitter and synapse and describe their roles in nervous system activity. Neurotransmitters are chemicals that assist in the transfer of signals from one neuron to another. Synapses are the tiny gaps between neurons across which they communicate: name and describe the two major divisions of the nervous system. The central nervous system consists of the brain and spinal cord, which are encased in bone for protection. Receives information, processes it, and determines what actions should result.
