What condition causes increasingly stronger contraction owing to increased stimulus strength?
Treppe
What organ system works with the muscular system to control muscular contractions?
The nervous system is what will initiate contractions as well as determine the strength of a contraction.
An action potential is triggered if?
If a neuron, or other excitable tissue, is stimulated by a stimulus of threshold strength or greater strength..
Is conducting stimulus strong enough to generate a nerve impulse?
It depends on the strength of the stimulus. A threshold voltage has to be reached before the nerve can be stimulated.
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
What condition causes increasingly stronger contraction owing to increased stimulus strength?
Treppe
What wave summation results in stronger contractions at the same stimulus strength because the muscle doesn't have time to completely what between successive stimuli?
Relax
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 does the strength of contractions depend?
Fha
What is the difference between stimulus frequency and stimulus strength?
<P> <P>The stimulus frequency is how often the stimulus is admitted. For example, every 30 seconds, every minute and 1/2, etc. <P>Stimulus strength describes the level of force used to administer the stimulus such as mild, moderate or maximum.</P>
What is the all none law of muscle response?
all-or-none law is the principle that the strength by which a nerve or muscle fiber responds to a stimulus is not dependent on the strength of the stimulus. If the stimulus is any strength above threshold, the nerve or muscle fiber will give a complete response or otherwise no response at all
Does the strength of a natural mangets can easily be increased?
The strength of a natural magnet can be increased.
Why is it important that summation not occur in heart muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
What organ system works with the muscular system to control muscular contractions?
The nervous system is what will initiate contractions as well as determine the strength of a contraction.
What potential does amplitude independent of stimulus strength describes?
action potential
The level of sensory stimulus strength at which an individual can detect the stimulus at least 50 percent of the time is called?
an absolute threshold
What happens when summation occurs in cardiac muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
