Document Summary
Sits very close to a dendritic spine on another neuron, although it does not. Synpase the space between the axon"s end foot and the neighboring touch that spine dendritic spine. Neurons are the information-conducting units of the nervous system: has special characteristics that allow it to send electrical impulses by using changes in chemical charges on its cell membrane. Overview of a neuron: the single axon limits the neuron to only one output channel for communication. A neuron is both an information-collecting and an information-processing device: receives a great deal of information on its hundreds to thousands of dendritic spines, but it has only one axon all the incoming signals. So the message that it sends must be averaged or summarized version of: information travels on a flow of electrical current that begins on the dendrites and travels along the axon to the terminals.
