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.

What is a frequency operated button?
A frequency operated button is a type of button or switch that operates based on specific radio frequency signals. These buttons are commonly used in remote control devices or wireless communication systems to trigger certain functions or actions wirelessly.
What does the transverse tubules do?
Transverse tubules are extensions of the cell membrane that help to transmit action potentials deep into the muscle fibers. They allow for the rapid and synchronized release of calcium ions from the sarcoplasmic reticulum to trigger muscle contraction.
How the unstable waves stables in oscilloscope?
Unstable waves can be stabilized on an oscilloscope by adjusting the trigger level and trigger slope settings. By setting the trigger level to a specific voltage and selecting the appropriate trigger slope (rising or falling edge), the oscilloscope will only display the waveform when it meets these trigger conditions, helping to stabilize the display of the waveform.
What is the major disadvantage of a free-running oscillator used to trigger an SCR or TRIAC?
One major disadvantage of a free-running oscillator is that it may not synchronize properly with the AC line frequency, causing timing errors and potential malfunction of the SCR or TRIAC. This can lead to inefficiencies and erratic behavior in the circuit.
How is light amplified in laser?
In a laser, light is amplified through a process called stimulated emission. This occurs when photons of light passing through a medium trigger atoms to emit more photons of the same frequency and direction in a cascading effect. This amplifies the intensity of the light beam and results in a coherent and focused laser output.
Given that action potentials traveling down the axon of a particular neuron are always the same amplitude how is a stronger stimulus communicated to the next cell in the neural pathway?
A stronger stimulus is communicated to the next cell in the neural pathway by increasing the frequency of action potentials generated by the neuron. A stronger stimulus will trigger action potentials to occur more frequently, which results in a higher frequency of signals being transmitted to the next cell.
Which of the stimuli resulted is the most effective nerve stimulation?
Electrical stimulation is typically the most effective method for nerve stimulation as it can directly trigger action potentials in the nerve fibers. Light and chemical stimuli can also stimulate nerves but are generally not as precise or efficient as electrical stimulation.
Can subthreshold stimulation cause an action potential?
No, subthreshold stimulation is not sufficient to trigger an action potential. The membrane potential needs to reach a certain threshold level for an action potential to be generated. Subthreshold stimulation only produces graded potentials that do not reach the threshold for firing an action potential.
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.
What is the minimal intensity of stimulation necessary to trigger a muscle contraction?
threshold stimulus

Action potentials originate at the?
Action potentials are how nerve impulses are transmitted from neuron to neuron. An action potential is formed when a stimulus to the nerve cell causes the membrane to depolarize and open all of its sodium ion channels toward the threshold potential.
Dendrites conduct both graded and action potential?
Dendrites primarily conduct graded potentials, which are local changes in membrane potential. These graded potentials can accumulate and trigger an action potential in the axon hillock if they reach a certain threshold. Action potentials are then conducted along the axon.
Action potentials trigger the release of chemicals in the terminal buttons called?
neurotransmitters. These neurotransmitters are released into the synaptic cleft to relay signals to the next neuron in the communication pathway.
What are the key differences between action potential and graded potential in terms of their mechanisms and functions?
Action potentials are rapid, all-or-nothing electrical signals that travel along the axon of a neuron, triggered by a threshold stimulus. Graded potentials are slower, variable electrical signals that occur in response to a stimulus, but do not necessarily reach the threshold for an action potential. Action potentials are essential for long-distance communication in the nervous system, while graded potentials play a role in short-distance signaling and can summate to trigger an action potential.
What can trigger the knifelike pain of trigeminal nerualgia?
Stimulation of the face, lips, or gums, such as talking, eating, shaving, tooth-brushing, touch, or even a current of air, may trigger the severe knifelike or shocklike pain of trigeminal neuralgia.
