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.


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.


When the frequency of stimulation of a muscle is great enough?

wave summation results and muscle twitches overlap.


What is adverse conditioning?

learning in which punishment or other unpleasant stimulation is used to reduce the frequency of an undesirable response


Would stimulation of arterial baroreceptors affect blood pressure?

yes


How does mass affect wave frequency?

lower mass = higher frequency


What are some ways muscle contractions can graded?

Muscle contraction can be: Concentric, Eccentric, Static.


What does adverse condition mean?

learning in which punishment or other unpleasant stimulation is used to reduce the frequency of an undesirable response


Does smiling affect brain chemistry?

No. Smiling is generally a response to emotional stimulation.


How does changing the frequency of the wave affect wavelength?

The wavelength changes inversely with the frequency.


Name four factors that influence contractile force and two that influence velocity and duration of contraction?

The four factors that influence contractile force are the number of muscle fibers stimulated, the relative size of the fibers, the frequency of stimulation and the degree of muscle stretch. Factors that influence the velocity and duration of contraction are the muscle fiber type, load and recruitment.
