Typically, the electrical signal that travels from the dendrites across the cell body travels by cable conduction properties (like cable TV). Once the signal reaches the axon hillock, which is the spot where the axon branches off the cell body, the electrical signal starts traveling by action potentials (and maybe some cable conduction). The signal travels to the terminal end of the axon where it initiates a calcium influx, which in turn initiates a release of neurotransmitter to act on the next, post-synaptic neuron. The axon is the long process (arm) that extends from the first cell body to the next neuron.
What else can I help you with?
Is a nerve impulse an electrical current that travels along dendrites or axons?
A nerve impulse, or action potential, is an electrical signal that primarily travels along the axon of a neuron, not the dendrites. Dendrites receive incoming signals from other neurons, while the axon transmits the impulse away from the cell body to other neurons or muscles. The impulse is generated by the movement of ions across the neuron's membrane, creating a rapid change in electrical charge.
The message that travels through a neuron?
The message that travels through a neuron is an electrical impulse called an action potential. It is generated when the neuron is stimulated and travels along the neuron's axon, facilitated by the movement of charged ions. This ultimately allows the neuron to communicate with other neurons or target cells.
A neuron transmits a nerve impulse as a wave of?
A neuron transmits a nerve impulse as a wave of electrical activity called an action potential. This action potential travels along the length of the neuron's axon and triggers the release of neurotransmitters at the synapse, allowing communication between neurons.
What name is given to a message that travels around the body in a nerve?
An electrical signal traveling along a nerve is called a nerve impulse or action potential.
Is action potential essential for impulse propogation?
Yes, action potential is essential for the propagation of impulses in neurons. It is the electrical signal that travels along the axon of a neuron, allowing the communication of information within the nervous system.

What are the main roles played by axon?
conducts electrical impulses away from the neuron's cell body or soma. It is basically what the nerve impulse travels along.

What is the direction of impulse in a neuron?
A nerve impulse travels toward the actual nucleus itself to pass information.
What name is given to a message that travels around the body in a nerve?
An electrical signal traveling along a nerve is called a nerve impulse or action potential.
What is the message that travels through the neuron?
An Impulse
How does an impulse cross a synape?
An electrical impulse travels along a nerve until it hits a synapse, where it causes the release of chemicals (neurotransmitters) which migrate across the synapse. At the other side , these neurotransmitters activate receptors which cause an electrical signal to continue along the nerve.
What is the brief electrical impulse transmitted along the axon called?
Butter Steak.
What causes a nerve impulse move along the nerve fiber?
Electrical diferences.
What cause a nerve impulse move along the nerve fiber?
Electrical diferences.
What muscles are used when you do step ups?
Various muscles of lower limb and back and hip.Each nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip. a nerve impulse travels along the neuron in the form of electrical and chemical signals.
