WOULD A SUBSTANCE THAT DECREASES MEMBRANE PROBABILITY TO SODIUM INCREASE OR DECREASE THE PROBABILITY OF GENERATING A NERVE IMPULSE?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.
What is the past tense of stimulus?
Stimulus is a noun, not a verb. Only verbs have tenses.
Is conducting stimulus strong enough to generate a nerve impulse?
Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.
Which is true of drugs that decrease membrane permeability to sodium ions?
It would decrease the probability of generating a nerve impulse. When a neuron is activiated by a threshold stimulus, the membrane briefly becomes more permeable to sodium. If the permeability is decreased, it will be more difficult for the sodium ions to rush into the cell.
An animal is an immediate automatic response to an external stimulus?
An animal's immediate automatic response to an external stimulus will vary depending on the circumstance. When the external environment is stimulated there is a response that is triggered.
What is a change that initiates an electrochemical message along a neuron?
When a neuron is stimulated, ions move across its membrane, creating a change in the electrical potential of the neuron. This change, known as an action potential, is propagated along the neuron's axon, allowing for the transmission of electrochemical signals.
A stimulus presented to a person or animal that decreases the probability of a particular response is known as?
Punishment by Application
What happens when a stimulus activates a receptor?
The activation of a second messenger inside the receiving cell, the triggering of enzyme activity in the cell, and the change of permeability of the cell.
When a nerve is activated by a threshold stimulus the membrane becomes more permeable to?
Potassium and Sodium
What is the type of feedback where the net effect is that the output of the system shuts off the original stimulus or reduces its intensity?
In a negative feedback loop, the output of the system decreases the intensity of the stimulus.
What do you need to file for stimulus refund for year 2013?
t do you file to recieve a stimulus check for a single person how much willit be
What is diffuson?
Stimulus Diffusion is where an idea is diffused or transmitted from one culture to another. This idea then is improved upon or has stimulated another idea or invention. C:
