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.

What affect does lowering extracellular calcium have on the resting membrane potential of a neuron?

Low calcium levels in the extracellular fluid increase the permeability of neuronal membranes to sodium ions, causing a progressive depolarization, which increases the possibility of action potentials. These action potentials may be spontaneously generated, causing contraction of skeletal muscles (tetany).


How does hyperkalemia affect action potential generation?

Hyperkalemia causes depolarization of the resting membrane potential, leading to reduced excitability of cells. This shift makes it harder for action potentials to fire, as the threshold for depolarization is increased. Additionally, hyperkalemia can alter the function of voltage-gated sodium channels, further impairing action potential generation.


What is the effect of increasing the foltage and how does this change correlate to changes in the nerve?

Increasing the voltage in a nerve can lead to an increased rate of nerve firing, resulting in more frequent action potentials. This can affect the overall excitability and sensitivity of the nerve. As voltage increases, the threshold for eliciting an action potential decreases, making the nerve more likely to fire in response to stimuli.


How does sound affect frequency?

The definition of sound is : "Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear." Sound can be measured by amplitude (loudness) and pitch (The frequency of the vibrations). Therefore sound does not affect frequency but frequency affects the pitch of the sound.


What factors affect the pitch?

Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.

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


When a neuron receives a stimulus that is very strong?

When a neuron receives a very strong stimulus, it may reach its threshold potential and fire an action potential. This can lead to the release of neurotransmitters, sending a signal to other neurons. The strength of the stimulus can affect the frequency of action potentials generated by the neuron.


What does recruitment and frequency of stimulation affect?

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 local graded potential?

Local graded potentials are small changes in membrane potential that occur in response to neurotransmitter binding to ligand-gated ion channels on the post-synaptic neuron. These potentials can summate and affect the likelihood that an action potential will be generated in the neuron. They are also referred to as synaptic potentials.

What would be the effect on action potential conduction at a region of axon where the disease had its effect?

The disease may disrupt the normal flow of ions necessary for generating and propagating action potentials, leading to decreased conduction velocity or even blockage of action potentials in that region of the axon. This could result in impaired communication between neurons and affect the overall function of the nervous system in that area.


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.


How does a drug that increases the length of time required for the repolarization of pacemaker cells affect the heat rate?

would decrease the heart rate, because the pacemaker cells would generate fewer action potentials per minute

Will coffee affect the brain?

Coffee, or any caffeinated drink, will not affect the brain directly, however it will effect the central nervous system by stimulation. The brain can be "affected" as a secondary response to the stimulation created in the central nervous system.
