An Impulse
Neurons communicate with other neurons through chemical and electrical signals. When one neuron is activated, it can stimulate adjacent neurons to transmit the signal further along the neural network.
What they relay is whether of not they were 'on' or 'off' and how often; and this occurs as an action potential firing frequency. There is no message in the sense that neurons might pass on complex messages, like an email for instance; or store memories of events and facts. No one neuron can do anything like that. It takes many neurons working together to achieve this.
nerve impulses
A neurotransmitter is released by neurons in order to signal other neurons, muscles, or glands.neurotransmittersneurotransmitters
In the nervous system, electrical signals travel along specialized cells called neurons. These signals are generated in the cell body of the neuron and then travel along the axon, which is a long extension that transmits the signal to other neurons or to muscles or glands.
The signal sent by a neuron is called an action potential. This electrical impulse travels along the neuron's axon and triggers the release of neurotransmitters at the synapse to communicate with other neurons or target cells.
The terminal buttons are located at the end of the neuron and are responsible for sending the signal on to other neurons. At the end of the terminal button is a gap known as asynapse. Neurotransmitters are used to carry the signal across the synapse to other neurons.
The process of signal transmission along a neuron is called "neuronal propagation." It occurs as an electrical signal travels from the dendrites to the cell body, down the axon, and finally to the axon terminals where neurotransmitters are released to communicate with other neurons.
A neuron releases a chemical called a neurotransmitter that will signal other neurons.
The two parts of neurons responsible for sensing and returning nerve impulses are the dendrites, which receive incoming signals from other neurons, and the axon, which transmits the signal away from the cell body to other neurons or target cells.
An action potential is a brief electrical signal that travels along a neuron's membrane. It is generated when the neuron is stimulated and involves a rapid change in voltage. This signal allows neurons to communicate with each other and transmit information throughout the nervous system.
