When the neuron is sufficiently stimulated this process occurs and triggers the action potential?
When a neuron is sufficiently stimulated, it reaches its threshold potential which causes voltage-gated sodium channels to open. This allows sodium ions to rush into the neuron, depolarizing the membrane and generating an action potential. This electrical signal then travels down the length of the neuron, allowing for communication with other neurons or target cells.
When the nerve cell is stimulated what is it called?
When a nerve cell is stimulated, the process is called depolarization. This occurs when the cell membrane's potential becomes less negative, leading to the generation of an action potential if the threshold is reached. The action potential then propagates along the nerve fiber, allowing for the transmission of signals.
What begins when a neuron is stimulated by another neuron or by the environment true or false?
From the axon terminal of another neuron, a bunch of chemicals (neurotransmitters) are released and travel across the synapse (junction of two neurons). If enough stimulate the second neuron, the total energy triggers another action potential. Short and simple explanation--message me if you want more info!
What is self propagated depolarization?
Self-propagated depolarization refers to the process by which an action potential triggers the opening of voltage-gated ion channels along the membrane, causing further depolarization in adjacent regions of the neuron. This process allows the action potential to travel down the length of the neuron, enabling rapid communication within the nervous system.
How does a neuron propagate nerve signals along its axon and to other neurons?
A neuron propagates nerve signals along its axon through a process called action potential, which involves a rapid change in electrical charge across the neuron's membrane. When a neuron is stimulated, sodium channels open, allowing sodium ions to rush in, causing depolarization. This electrical impulse travels along the axon, and when it reaches the axon terminals, it triggers the release of neurotransmitters into the synapse, allowing the signal to be transmitted to other neurons. This sequential process enables rapid communication within the nervous system.

What is the initial factor that triggers the process of photosynthesis?
The initial factor that triggers the process of photosynthesis is sunlight.
What is the difference between spontaneous emission and stimulated emission?
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
Why Stimulated Emission Is Used In Laser?
Stimulated emission is used in lasers to produce coherent light. When a photon collides with an excited atom, it triggers the emission of another photon that is coherent with the first, leading to the amplification of light. This process allows for the creation of a focused beam of intense light with specific characteristics, making it useful in a wide range of applications.
What is the difference between spontaneous and stimulated emission of light?
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
Principle of Spontaneous emission and stimulated emission?
Spontaneous emission is the process where an atom or molecule transitions from a higher energy state to a lower energy state, emitting a photon in the process without any external stimulation. Stimulated emission occurs when an incoming photon triggers an atom or molecule already in an excited state to emit a second photon that has the same wavelength, phase, and direction as the incoming photon, resulting in the amplification of light.

When a section of the resting neuron is stimulated?
When a section of a resting neuron is stimulated, it causes a localized change in membrane potential, typically depolarization. This change occurs because sodium channels open, allowing Na+ ions to flow into the neuron. If the depolarization reaches a certain threshold, it can trigger an action potential, leading to the propagation of the signal along the axon. This process is crucial for neural communication and the transmission of information throughout the nervous system.
What is expansion of laser?
The expansion of LASER is Light Amplification by Stimulated Emission of Radiation. This process involves generating a highly concentrated beam of coherent light through stimulated emission in a gain medium.
What is self propagated depolarization?
Self-propagated depolarization refers to the process by which an action potential triggers the opening of voltage-gated ion channels along the membrane, causing further depolarization in adjacent regions of the neuron. This process allows the action potential to travel down the length of the neuron, enabling rapid communication within the nervous system.
