Document Summary

Sensory neurons: lights, sounds, odors, tastes. Motor neurons: responsible for movements of muscles. Inside the cns: local interneurons: form circuits with nearby neurons and analyze small pieces of information, relay interneurons: connect circuits of local interneurons in one region of the brain with those in other regions. Dendrites: communication through synapses, look like trees. Serve as important recipients of the messages of other neurons: synapse: junction between the terminal buttons of the sending cell and a portion of the somatic or dendritic membrane of the receiving cell. Messages that pass from neuron to neuron are transmitted across the synapse. Terminal buttons: release neurotransmitters (chemicals that either excites or inhibits the receiving cell and thus helps to determine whether an action potential occurs in its axon, forms synapses with other neurons.
