What is the different between an external stimulus and an internal stimulus?
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
In positive feedback the initial stimulus produces a response that the stimulus?
exagerrates the stimulus
What is a change in an organism's surrounding that causes the organism to react?
The answer to this would mose probabaly be a stimulus. Because there are 2 types of stimuli Internal Stimulus and External Stimulus and so it has to be either one of these but the answer is stimulus.
Is the sudden drop in air temperature a stimulus or response?
The sudden drop in air temperature is a stimulus.
Which type of stimulus is an allergen such as pollen?
External Stimulus
What is the definition of maximal stimulus?
The maximal stimulus is the strongest stimulus that produces increased muscle contractile force.
What has happened in the muscle when the maximal stimulus is achieved?
Each of the individual muscle fibers in the muscle are contracted when the maximal stimulus is achieved. Dr. H.
What is this tetanus stimulus frequency called?
Maximal Tetanus Tension
The strongest muscle contractions are normally achieved by?
Increasing stimulation up to the maximal stimulus
What is the definition of a submaximal stimulus?
A submaximal stimulus refers to an intensity level of a stimulus that is below the maximum level that a system or organism can respond to. It is often used in exercise physiology to describe a workload that does not elicit a maximal performance or physiological response.
Strong stimuli cause the amplitude of action potentials generated to increase?
Yes, strong stimuli can cause an increase in the amplitude of action potentials generated by neurons. This is known as recruitment of more neurons or an increase in the frequency of action potentials to convey the stronger stimulus information.
What voltage produced maximal contraction of the muscle?
The voltage that produces maximal contraction of a muscle is called the maximal stimulus voltage. This voltage is typically higher than the threshold voltage required to elicit a muscle contraction and ensures that all muscle fibers within a motor unit are stimulated to contract simultaneously, leading to a stronger contraction.
What principle states that the properties of the action potential are independent of the relative strength of the depolarizing stimulus?
The all-or-none principle states that the properties of an action potential, such as amplitude and duration, are independent of the intensity of the stimulus that triggers it. This means that once a threshold stimulus is reached, the action potential will fire at maximal strength regardless of the strength of the initial stimulus.
What is maximal speed?
Maximal strength is when your stamina improves in your muscle's.
What does the medical abbreviation PMI mean?
Point Of Maximal ImpulsePoint of Maximum impulse or Point of Maximum Intensitypoint of maximal intensitypoint of maximal impulse
Why is there a maximal voltage for muscles?
All of the muscles in the muscle fiber have contracted when there is a maximal voltage and there is a maximal voltage to prevent injury to our muscles. Dr. Sayed
How would the relationship between the stimulus voltage and the amplitude of the response differ on a single nerve fiber?
The relationship between stimulus voltage and response amplitude on a single nerve fiber follows the all-or-nothing principle. Below a certain threshold voltage, there will be no response. Once the threshold is reached, there will be a maximal response amplitude without variation with higher stimulus voltage.
