How Does An Electrical Signal Travel Through A Neuron . Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells. However, a small space appears there, and this is the synapse.

Yes, an electrical signal is passed from the dendrites of 1 motor neuron, through it's cell body, through it's axon (the long tail looking feature of the neuron). Electrical signals always go in the same direction. A synapse is a small gap between two neurons that are trying to send a message to one another.

Electrical signals always go in the same direction. The signal may be directly transferred at electrical synapses or, if there is no physical link between adjacent neurons, the signal is carried across the gap by chemicals called neurotransmitters. The signal travels out through the axon. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.

The dendrites of the first neuron in the signal chain receives the stimulus and transmit the signal through the axon. Electrical current in physiology consists of a stream of atoms called ions. Nervous system messages travel through neurons as electrical signals. When the signal reaches the terminal it causes the release of synaptic vesicles that carry a neurotransmitter (chemical messengers)..

In turn, electrical communication occurs via two main mechanisms: The number of interconnections can be far greater than shown here. Signals travel along the axon of a neuron (which we will call neuron a) in the form of an electrical impulse.
