Acetylcholine (ACh) is the neurotransmitter that passes from neuron to muscle cells and it causes the Na/K channels to open allowing Na+ to flow into the cell triggering an action potential.
A nerve impulse passes from an axon terminal of one neuron to another neuron across a synaptic gap.
A relay neurone passes impulses from a sensory neurone to a motor neurone.
There are two types of responses to stimuli. 1)Deep response which requires integration by the brain such as thinking. 2)Simple response which is done by reflex arc. The reflex Arc is consisted if receptor, sensory neuron, relay neuron, motor neuron and effector which is either muscle or gland. For example in humans. If your hand touches a hot object. Heat receptors in your hand will act as sensor, passing an impulse by generating action potential in the sensory neuron. The sensory neuron passes the impulse to along it till reaching the spinal cord passing the impulse to the relay neuron by a process called synapse. The relay neuron synapse with motor neuron to pass the impulse to it. The end of the motor neuron is connected to the bi-ceps muscle in the arm. As the impulse reaches the end of the motor neuron it passes impulse to the muscle ordering it to contract, thus the hand is removed away from stimulus. This process take a fraction of a second.
Signalling ALONG a neuron is electrical, but signalling BETWEEN neurons is a chemical process. Neuron A 'passes' a message onto the next by releasing chemicals called neurotransmitters , which are then taken up by neuron B. The point at which these neurotransmitters are released from the neuron A is called the 'terminal bouton' and is the end of its axon. More specifically, it is the presynaptic membrane OF the terminal bouton at which the passing on of a message occurs.
Okay, information is received through the dendrites, and then moves on the the cell body. From there, the cell's axon passes the message on to other neurons or to muscles or glands.

A relay neurone passes impulses from a sensory neurone to a motor neurone.
the image passes from neuron to neuron through neurotransmitters until it reaches the brain, where the neurotransmitters are read

An axon terminal is the structure of a neuron (a single cell of the central or peripheral nervous system) at the end of it's axon that forms a synapse with another neuron. Generally, the axon terminal is the point at which a neuron passes information to the neurons with which it is connected.

After a neuron fires, there is a refractory period where certain factors in the neuron prevent it from being depolarized again. This is made possible by an "overshoot" of polarization (returning to a much stronger negative ion charge inside the neuron) after the action potential passes. This ensures that voltage-controlled ion channels remain closed for a small period of time and do not become overactive through continuous restimulation.
actually we must say all neurons receive information. there are three types of neurons: 1.sensory neuron 2.motor neuron 3.relay neuron the sensory neurons receive information from receptor cells in sense organs and pass the information from sensory neuron to the other and pass the info to spinal cord where they are received by relay neuron. this neuron in turn passes the info to motor neurons which pass the info to cells in effectors and action is performed.relay neurons are messengers between sensory neuron and motor neuron in spinal cord.
