Recruitment affects the number of motor units activated in a muscle, while frequency of stimulation affects the force generated by those motor units. Increasing recruitment leads to more muscle fibers being recruited, increasing force production, while increasing frequency of stimulation produces stronger muscle contractions by increasing the rate at which motor units are activated.

What is the force frequency relationship and how does it impact the behavior of a system?

The force-frequency relationship refers to how the force produced by a muscle or system changes with the frequency of stimulation. In general, as the frequency of stimulation increases, the force produced by the muscle also increases. This relationship impacts the behavior of the system by influencing its ability to generate force and perform tasks efficiently at different frequencies of stimulation.


Would increasing frequency of stimulation to trigger zone change number of action potentials?

Yes, increasing the frequency of stimulation can increase the number of action potentials generated in the neuron. This is known as frequency-dependent facilitation, where rapid succession of stimuli can enhance the excitability of the neuron and lead to more action potentials being fired.


Why does the number of action potentials vary with increased stimulation frequency?

Increased stimulation frequency can lead to a phenomenon called summation, where individual action potentials merge together or "sum" to produce a larger response. This allows for greater depolarization of the membrane potential, leading to more frequent firing of action potentials. As the stimulation frequency increases, the membrane may not return to its resting potential before receiving the next stimulus, resulting in a higher number of action potentials being generated.


How does amplification affect frequency?

Amplification does not affect the frequency of a signal. It simply increases the strength or magnitude of the signal without changing its frequency. A properly designed amplifier will preserve the frequency content of the input signal while boosting its amplitude.


How does the amplitude and frequency affect wavelength?

The amplitude of a wave does not affect its wavelength as wavelength is determined by the speed of the wave and its frequency. Frequency and wavelength are inversely proportional; as frequency increases, wavelength decreases, and vice versa. This relationship is expressed mathematically as wavelength = speed of the wave / frequency.

How does frequency of stimulation affect action potentials?

The frequency of stimulation can affect the action potential by influencing the rate at which action potentials are generated in a neuron. Higher frequency stimulation can lead to more action potentials being fired in a shorter amount of time, while lower frequency stimulation may result in fewer action potentials being generated. This relationship is known as frequency-dependent facilitation or depression.


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?

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.


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.

Yes, increasing the frequency of stimulation can increase the number of action potentials generated in the neuron. This is known as frequency-dependent facilitation, where rapid succession of stimuli can enhance the excitability of the neuron and lead to more action potentials being fired.


What happens to the amount of total force the muscle generates during the stimulated twitch?

The total force that a muscle generates during a stimulated twitch depends on the frequency and intensity of the stimulation. In general, as the stimulation frequency increases, the force generated by the muscle also increases up to a point, where it reaches a plateau known as tetanus. After this point, increasing the stimulation frequency further does not significantly increase the force output.
