What condition causes increasingly stronger contraction owing to increased stimulus strength?
Treppe
The minimal strength of stimulation needed to elicit a muscle contraction is called the threshold stimulus?
true
What is muscle treppe?
•Increased contraction in response to multiple stimuli of same strength
How does the frequency of stimulation affect the amount of force generated by the muscle?
Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
What is a graded muscle response?
It is the variation of stimulation needed in skeletal muscle contraction in order to have controlled movement.
Does all body cells exhibit irritability to some extent?
Muscle cells are irritable and respond to stimuli. Muscle twitch is defined as contraction and relaxation in the muscle cell. The stimulus needs to be above a certain threshold for the muscle fibres to react. The more the stimulus, the greater the strength of the contraction.
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 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 relationship between the load on a muscle and its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
What is the Relationship between a load on a muscle its strength of contraction?
Strength of contraction increases as the load increases until the load becomes excessive.
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.
