What is the first response a neuron makes to a stimulus?
The first response a neuron makes to a stimulus is called depolarization. This is when the neuron's electrical charge changes, allowing it to transmit an electrical signal down its length to communicate with other neurons.
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.
Which neurons decide about the action for a certain stimulus?
Sensory neuron
What is the stimulus-response pathway involving a sensory neuron and a motor neuron?

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.
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.
The strong stimulus can increase the?
Number of times the neuron fires
What is the pathway a stimulus followed to produce a response?
the neuron pathway
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. )
When a neuron receives a stimulus that is very strong?
When a neuron receives a very strong stimulus, it may reach its threshold potential and fire an action potential. This can lead to the release of neurotransmitters, sending a signal to other neurons. The strength of the stimulus can affect the frequency of action potentials generated by the neuron.
What is the area of neuron that detect a stimulus?
The area of a neuron that detects a stimulus is primarily the dendrites, which are the branching extensions of the neuron. Dendrites receive signals from other neurons or sensory receptors and transmit these signals toward the cell body. In sensory neurons, specific receptors located on the dendrites are specialized to detect stimuli such as light, sound, or touch. This initial detection is crucial for initiating the neuronal response to various environmental signals.
