Document Summary

Brain and cognition 2 thursday september 15, 2016. A cell that accumulates and transmits electrochemical activity in the nervous system. There are approximately 100 billion neurons in the human brain that are simultaneously active to process information. Neurons change in density as you age, or learn new things. Dendrites- where information comes into the neuron, they wait for input. Terminal where neuron transmitters are released and connected to other neurons. Myelin sheath fatty tissue, a type of conductor. Branch-like structures extending from the cell soma (cell body) Receive information from terminal buttons of adjacent neurons. Varies in length (from a mm to km) Provides the fixed paths by which neurons communicate with one another. Ball-like structures at the ends of axon branches. Near-contact gap separating the terminal bouton of one neuron and the dendrite (or some) of the next neuron in the chain.
