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.

Stimulus threshold of the neuron refers to what?
The stimulus threshold of a neuron, often referred to as the action potential threshold, is the minimum level of stimulation required to trigger an electrical impulse (action potential) in the neuron. When a stimulus exceeds this threshold, it causes sufficient depolarization of the neuron's membrane, leading to the rapid influx of sodium ions and the subsequent propagation of the action potential along the axon. If the stimulus is below this threshold, the neuron remains inactive, and no action potential is generated.
Minimum level of stimulation required to trigger a neural impulse?
The minimum level of stimulation required to trigger a neural impulse is known as the "threshold." This threshold is the minimum amount of neurotransmitter release or electrical stimulation needed to generate an action potential in a neuron. Below this threshold, the neuron will not fire an action potential.
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 are the 5 steps to a reflex arc?
Arrival of stimulus, Activation of a sensory neuron, Information processing by an interneuron, Activation of a motor neuron, The response by an effector. Straight out of my anatomy text book.
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
What is a Specialized area of sensory neuron that detects a specific stimulus?
A specialized area of sensory neuron that detects a specific stimulus is called a sensory receptor. These receptors are designed to respond to specific forms of stimulation, such as touch, light, or sound, and convert the energy from these stimuli into electrical signals that the nervous system can interpret.
Which neurons decide about the action for a certain stimulus?
Sensory neuron
What is the sequence of events that correlates to the sequence of events of a nerve impulse?
2,1,3,4
What is the stimulus-response pathway involving a sensory neuron and a motor neuron?
Please see:What_happens_at_the_level_of_the_neuron_starting_with_stimulus_and_ending_with_a_response
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.
What makes a neuron receive a stimulus?
An interaction with the world.
The strong stimulus can increase the?
Number of times the neuron fires
