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.
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 the membrane action potential get to the sarcoplasmic reticulum?
The membrane action potential triggers the release of calcium ions from the sarcoplasmic reticulum through a process called excitation-contraction coupling. This is mediated by the protein complex known as the ryanodine receptor, which allows calcium to flow out of the sarcoplasmic reticulum and into the cytoplasm upon stimulation by the action potential.
What goes on when an action potential is transferred from one neuron to the next through a synapse?
When an action potential reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential. This process either excites or inhibits the postsynaptic neuron, depending on the neurotransmitter and receptor type involved.

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.

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.
