What happens during a nerve impulse?

A nerve impulse is an electrical phenomenon that occurs because of a difference in electrical charge across the plasma membrane of a neuron. The action potential travels rapidly down the neuron's axon as an electric current. A nerve impulse is transmitted to another cell at either an electrical or a chemical synapse.

Likewise, what occurs during nerve impulse?

A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that carry the nerve impulse to the next cell.

Also Know, how fast is a nerve impulse? Signals can travel as slow as about 1 mph or as fast as about 268 mph. Axon – a long, single nerve fiber that transmits messages, via chemical and electrical impulses, from the body of a neuron to dendrites of other neurons, or directly to body tissues such as muscles.

Similarly, what is the order of a nerve impulse?

Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse. A synapse is the junction between each axon tip and the next structure.

How is a nerve impulse propagated?

The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane.
