Mechanical stimulation of a nerve physically opens ion channels in the cell membrane, allowing ions such as sodium and potassium to flow across the membrane. This creates a change in the electrical charge inside the nerve cell, leading to depolarization and generation of an action potential.
What else can I help you with?
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.
Why would thermal stimulation increase an action potential?
By applying a thermal stimulation into the nerve, means you stimulate it. So with a thermal stimulation, you're already made a possibility to increase the Na+ flow faster.Because as heat, Na ions will move faster than room temperature. They move faster, cause the flow move faster, then the stimulate reach the threshold or even more than that.. causes the increased of action potential
Does strong stimuli cause the strength of action potentials to increase?
No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
Disturbances when will sensory neurons result in an action potential?
Disturbances to sensory neurons can cause depolarization of the neuron's membrane, reaching a threshold that triggers an action potential. This action potential then travels along the neuron's axon to the central nervous system, where it is processed and interpreted as a sensory experience.
Can water cause mechanical weathering?
Yes, water can cause mechanical weathering through processes such as freeze-thaw action and abrasion. When water freezes and expands in cracks in rocks, it can break them apart. Additionally, flowing water can carry sediments that abrade and wear away rocks over time.
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.

Do plants have the potential to cause mechanical weathering?
yes but he did leave
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
Why does injection of a local anesthetic into a finger still cause a loss of the sensation of touch from the finger?
Touch stimulation of this sensory receptor will open the mechanically gated ion channels, but action potentials are still not initiated because propagation of an action potential requires the opening of voltage-gated Na+ channels
What is a cause of a mechanical energy?
A cause of mechanical energy is the motion of an object due to its position or movement. This energy can be transformed between potential energy (stored energy based on position) and kinetic energy (energy of motion).
Does strong stimuli cause the strength of action potentials to increase?
No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
Why does meth amphetamine cause wildly sexual stimulation when other times there is none?
Methamphetamine can cause wild sexual stimulation when a person does not have this stimulation on a regular basis because the drug can cause the body to produce more hormones.
Does nipple stimulation cause a miscarriage?
no
What cause mechanical weathering?
Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion
Which fibers carry action potential to cause skeletal muscles to contract?
Alpha motor neurons
Do action potential cause electrical and chemical change in neuron?
Yes, you see when a action potential process is taking place the negative ions are in the center of the nerve and the positives are on the outside, during the action potential however they swap places, which in doing so changes the electrical and chemicals in the nerve cell.
