Document Summary

Neurons are the basic communication links in the nervous system. They normally transmit a neural impulse (electrical current) along an axon to a synapse with another neuron. The neural impulse is a brief change in a neuron"s electrical charge that moves along the axon. Action potentials trigger the release of chemicals called neurotransmitters that diffuse across a synapse to communicate with other neurons. Transmitters bind with receptors in the postsynaptic cell membrane, causing excitatory. Most neurons are linked in neural pathways, circuits and networks inhibitory psp"s. Ach plays a key role in muscular movements. Disturbances in the activity of the monoamine transmitters have been related to the development of depression and schizophrenia. Gaba is a widely distributed inhibitory transmitter. The nervous system can be divided into the central nervous system and the peripheral nervous system. Central nervous system consists of the brain and the spinal cord.
