The action potential stimulates the axon terminal to release its neurotransmitters. The neurotransmitters attach themselves to the dendrote of the next neuron, so that it will open its NA+ channels.

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.
In a neuron impulses move?
In a neuron, impulses move from dendrite to axon. These impulses carry energy to different parts of the neuron.
Do graded potentials increase amplitude as they move away from the stimulus?
No, they actually decrease in amplitude as they move away from the stimulus point.
What is the difference between reLAy neuron and motor neuron?
Motor nerves tell muscles to contract, thereby making you move.
What is the difference between associate neuron and motor neuron?
motor neurons are linked to the muscles and obviously sends a message for muscles to move
Where does an impulse move from on neuron to the other?

In a neuron impulses move?
In a neuron, impulses move from dendrite to axon. These impulses carry energy to different parts of the neuron.
What is a small space across which an impulse travels to move from on neuron to another?
It's most likely called a synapse
What is A small space across which an impulse travels to move from one neuron to another?
Synapse. The gap itself is called the synapticcleft.
A small space across which an impulse travels to move from one neuron to another?
It is most definitely a synapse.
How does the nerve signal move through the neuron?
in transmitting a nerve signal such as from your hand to your brain, several neurons are involved. Nerve cells can receive and transmit signals.the dendrites of one neuron are close to the axon of another neuron. The point where neurons meet is called a synapse
What is the sequence of structures that action potentials must move through to excite skeletal muscle contraction?
Excitation begins as a motor neuron transmits an action potential to the neuromuscular junction where it gets propagated along the muscle cell. This action potential is an electrical impulse that depolarizes the muscle cell membrane, the sarcolemma, which then releases ions in the sacroplasmic reticulum and transverse tubules. When this happens calcium is released into the sarcomeres that contain actin and myosin myofilaments. The calcium unlocks the binding sites and creates crossbridges with the globular heads on the mysoin fibers. With ATP as the energy source, this crossbridging brings the Z-lines closed together and the muscle fiber contracts.
If an impulse traveled down one neuron but failed to move on to the next neuron what happened to the first neuron?
Vesicle are not fusing with the membrane and releasing neurotransmitter.
Do blood cells move from the axon terminal to the dendrites?
Technically a neural impulse moves from the cell body to the axon terminal, because a nerve impulse is defined as an electrical signal that travels along an AXON.This may be confusing because neural signals move in three places with respect to the neurons, in three correspondingly different ways, and only one is called the neural impulse.Neural signals move in these places: betweenneurons (ie, from one neuron to another), intoneurons, and along axons (the outputs of neurons, when a neuron has fired).BETWEEN NEURONS: A neural signal can be passed from one neuron to another, at a synapse, across the synaptic cleft, by the release of chemicals called neurotransmittersfrom the presynaptic neuron, which diffuse across the synaptic cleft, to fit into receptors on the postsynaptic neuron. This is a chemical transmission of the neural signal, not an impulse.INTO A NEURON: when a signal has passed from one neuron to another by the release, diffusion, and reception of neurotransmitters, it initiates a graded response in the dendrites of the postsynaptic neuron, which travels with decreasing strength down the dendrites and across the soma (cell body), until it reaches the root of the axon, the axon hillock. This graded response is also not an impulse.ALONG THE AXON: if enough graded response signalsreach the axon hillock at about the same time, (it might be helpful to think of them as degraded signals, since they get weaker the further they travel), such that their combined strengths can trigger an all or nothing action potential in the axon, then it can be said that the neuron has fired a neuronal impulse.So, there are neural signals which move betweenneurons and into neurons, and neural impulses which fire and move along axons from the cell body (soma).
Why is a neuron called an interneuron?
A neuron is called a inter-neuron because that specific neuron takes impulse from one neuron to a next neuron. For example your sensory neuron sends a impulse that you had felt a hot object. It goes through the spine to a inter-neuron to a motor neuron (this processes is called a reflex). Then the motor neuron tells your muscles in your hand to move
Do graded potentials increase amplitude as they move away from the stimulus?
No, they actually decrease in amplitude as they move away from the stimulus point.
Why is it helpful to have impulses move only in one direction in a neuron-?
Nerve impulses travel one direction because of the action potential which is created because of Na+ and when K+ returns to normal.
