If a neuron is not sending out an impulse or signal, this means the neuron is at rest. Neurons send signals electrochemically.

What is a neuron impulse?
it is neuron impulse
List the cellular structures over which an impulse would pass?
In the body, an electrical impulse travels through the neurons, or nerve cells, to send signals to and from the brain. The Dendrites of the neuron accept the impulse, send it through the soma, down the axon, and to the axon terminal, where it'll be sent to the next neuron, almost instantly.
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
What are the sources of stimulation that start a nerve impulse?
An impulse begins when a neuron is stimulated by another neuron or by the environment.
What Three kinds of neutrons that would be involved in a reflex impulse?
They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.

What steps involved in transmitting the impulse from one neuron to another and then to the muscle fiber?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineEach 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.Acetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
How is a nerve specialised to carry out its function?
A nerve cell is called a neuron. The neuron has dendrites that receive impules from the previous neuron and send it to the cell body and an axon that transmits the impulse to the next neuron. There is a space between one cell's axon and the next cell's dendrites called a synapse. Neurotransmitters are released from the axon terminal to carry the impulse across the synapse.
What travels through the neuron?
An electrical impulse will travel through a neuron.
What begins when a neuron is stimulate by another neuron in its environment?
A nerve impulse
If a motor neuron in the body were stimulated by an electrode placed about midpoint along the length of the axon?
the impulse would spread bidirectionally
Why would a lack of neurotransmitters cause problems?
neurotransmitters send signals from neuron to neuron
