How did the frequency of stimulation affect the amount of force generated by the isolated skeletal muscle when the frequency of stimulation was increased such that the muscle twitches did not fully re?
Decreased force production
Why does the force of a muscle decrease over time during uninterrupted stimulation?
The muscle is said to undergo Fatigue.
When the frequency of stimulation of a muscle is great enough?
wave summation results and muscle twitches overlap.
What are some ways muscle contractions can graded?
Muscle contraction can be: Concentric, Eccentric, Static.
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 four factors determine muscle tension?
Muscle contraction is affected by four factors:1. The number of muscle fibers stimulated 2. The relative size of the fibers 3. Frequency of stimulation 4. The degree of muscle strength
Is Cardiac muscle stimulation neural?
No, but skeletal muscle is.
What conclusions can you draw about the relationship between a muscle's workload and its threshold of stimulation?
As the muscle workload increase, its threshold of stimulation increases.
After nervous stimulation of the muscle cell has ceased the calcium in the muscle?
uhhh
What muscle can contract without the need for the nervous stimulation?
Smooth & cardiac muscle.
What is the substance that halts stimulation of muscle tissue?
Acetylcholine
What types of muscle tissue can depolarize spontaneously in the absence of any external stimulation?
cardiac muscle and smooth muscle?
