What events occur in a neuron between the stimulus of a nerve and the stimulation of its target cell?

When a nerve is stimulated, its cell membrane is depolarised so that the inside of the cell becomes less
negative. The potential is conducted along the axon to the axon terminal. At the dendrite it stimulates the
release of a chemical transmitter, which diffuses across a synapse. The transmitter binds to receptor sites
on the postsynaptic cell membrane to stimulate the generation of another impulse.

How does a neuron indicate the strength of a stimulus?
A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
What stimulus below this intensity will result in no response in a neuron?
Threshold stimulus
Which neurons decide about the action for a certain stimulus?
Sensory neuron
What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
Minimum level of stimulation required to trigger a neural impulse?
An action potential needs to occur to trigger the neurons but the action potential depends on whether a stimulus is able to bring the membrane potential to a certain level termed the THRESHOLD. This threshold is about -55 mV for most neurons, but the stimulus needs to bring the membrane potential to this certain level or it will not be triggered. Relating to the ALL-OR-NONE PRINCIPLE, which if the threshold is not acquired then an action potential will not occur but once a stimulus is strong enough to depolarize (making the inside of the cell less negative going from -70 mV to -55 mV) it will trigger. The resting potential is -70 mV which the stimulus needs to bring it up to -55mV.
What is the stimulus-response pathway involving a sensory neuron and a motor neuron?

What makes a neuron receive a stimulus?
An interaction with the world.
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 is the pathway a stimulus followed to produce a response?
the neuron pathway
The strong stimulus can increase the?
Number of times the neuron fires
When a stimulus acts on a neuron it decreases the permeability of the stimulated point of its membrane to sodium ions?
False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
