It simply and completely self destructs. You see, once the threshold is reached it no longer can sustance its physical structure due to power surges. This results in an power overload just like when a star such as the sun reaches critical level and eventually explodes resulting in a Supernova.
The "all or none" law states that a neuron will either fire at full strength or not at all in response to a stimulus. This means that once a neuron reaches its threshold for firing, it will generate an action potential of consistent strength. If the stimulus is below the threshold, the neuron will not fire. This law helps to ensure the reliability and efficiency of communication within the nervous system.
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.
When a neuron is above its threshold level, it generates an action potential. This is an electrical impulse that travels down the neuron's axon, triggering the release of neurotransmitters at the synapse. This allows communication with other neurons or muscles.
Its where there are a lot of sodium channels. Once the trigger zone is 'triggered' to threshold (from -70mV to -55mv), then an action potential occurs. trigger zone in MOTOR neurons are in the axon hillock and in SENSORY neurons, they're in the 1st unmyelinated area (first node of ranvier).
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
A neuron fires when its membrane reaches a certain threshold potential. This threshold potential is typically around -55 to -65 millivolts. When the membrane potential reaches this level, an action potential is triggered and the neuron fires.
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
The "all or none" law states that a neuron will either fire at full strength or not at all in response to a stimulus.

This law helps to ensure the reliability and efficiency of communication within the nervous system.
Increasing the stimulus intensity past the threshold level for a neuron will not further increase the action potential generated. Once the threshold is reached, the neuron will fire an action potential at its maximum intensity.
When a neuron reaches its threshold, it initiates an action potential. This is a brief electrical impulse that allows for communication between neurons. The action potential travels down the axon of the neuron to transmit signals to other neurons or cells.
A neuron reaches its trigger point when the combined inputs it receives from other neurons or sensory receptors exceed a certain threshold. Once this threshold is reached, the neuron generates an action potential, which propagates down its axon to communicate with other neurons or muscle cells.
The minimum level of stimulation required to trigger a neural impulse is known as the "threshold." This threshold is the minimum amount of neurotransmitter release or electrical stimulation needed to generate an action potential in a neuron. Below this threshold, the neuron will not fire an action potential.
the membrane potential of a neuron reaches a threshold level, typically around -55mV. At this point, voltage-gated sodium channels open, allowing an influx of sodium ions that depolarizes the cell and initiates an action potential.
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
The all-or-none principle in physiology states that once a nerve impulse reaches a certain threshold, a neuron will fire at its maximum potential. If the stimulus is strong enough to trigger an action potential, the response will occur at full strength. If the stimulus is below the threshold, no response will be triggered.
Threshold stimulus is defined as the minimum level of stimulus intensity that is required to trigger a response in a neuron or muscle fiber. This level must be reached for action potentials to be generated, leading to muscle contraction or nerve signal transmission. If the stimulus is below this threshold, no response occurs, highlighting the all-or-nothing principle of action potentials.
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.
