What is an Activity that combines muscle contraction with repeated movement?
An activity that combines muscle contraction with repeated movement is Isotonic execrise
What is the minimal stimulus needed to elicit a muscle contraction is called?
Threshold Stimulation
What is the minimal intensity of stimulation necessary to trigger a muscle contraction?
threshold stimulus
What is the minimal strengh of stimulation needed to elicit a muscle fiber contraction called?
Threshold
What is the minimal level of stimulus to cause a muscle contraction?
it is known as the threshold stimulus usually seen in tonic contraction
The minimal strength of stimulation needed to elicit a muscle contraction is called the threshold stimulus?
true
What is the minimal impulse that can initiate a muscle contraction?
Threshold stimulusThe minimal level of stimulation required to cause a fiber to contract is called the THRESHOLD STILULUS.
What is the component in muscle tissue that contains the ATPase activity required for contraction?
myosin
Does cardiac electrical activity immediately precede the contraction of the cardiac muscle?
Yes
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 assist in returning blood to the heart?
skeletal muscle contraction gravity respiratory activity valves
What are biopotential?
Eletric activities produced by a tissue of the body, such as in a muscle contraction, a heartbeat or even a brain activity.
