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 happens when a neuron is stimulated by another neuron?
When a neuron is stimulated by another neuron, an action potential is generated and travels down the axon of the stimulated neuron. This action potential triggers the release of neurotransmitters at the synapse, which then binds to receptors on the postsynaptic neuron, leading to either excitation or inhibition of the postsynaptic neuron.
What are the sources of stimulation that start a nerve impulse?
Sources of stimulation that can start a nerve impulse include chemical signals (neurotransmitters released at synapses), physical stimuli (such as pressure or temperature changes acting on sensory receptors), and electrical signals (generated by neighboring neurons or external electrical sources). These stimulations can trigger the opening of ion channels in the neuron's membrane, leading to changes in membrane potential and initiation of an action potential.
When the neuron is sussiciently stimulated this process and triggers the action potential?
When a neuron is sufficiently stimulated, it depolarizes, allowing sodium ions to rush into the cell, triggering an action potential. The action potential travels down the length of the neuron, causing the release of neurotransmitters at the synapse and facilitating communication with other neurons.
The start of an action potential?
The action potential begins when the neuron is stimulated and reaches a certain threshold of excitation. This causes voltage-gated ion channels to open, allowing a rapid influx of sodium ions into the neuron, leading to depolarization. This depolarization triggers a cascading effect along the neuron's membrane, resulting in the propagation of the action potential.
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 stimulate by another neuron in its environment?
A nerve impulse

When neuron stimulated enough it?
When a neuron is stimulated enough, it reaches its threshold potential and fires an action potential. This action potential travels down the axon of the neuron, allowing for the communication of signals to other neurons or cells.
What does it mean by a neuron is highly irritable?
irritability (ability to be stimulated)
What is mean by a neuron is highly irritable?
irritability (ability to be stimulated)
When a stimulus acts on a neuron it decreases the permeability of the stimulated point of its membrane to sodium ions?
False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
How is a skeletal muscle fiber stimulated by a motor neuron?

What type of neuron begins a reflex arc?
A sensory receptor is the type of neuron that begins a reflex arc.
How do you use neuron in a sentence?
you are neuron to the environment
What is the main part of the of a neuron?
It depends on what you mean by 'main'. The AXON is the part which CONVEYS the neural impulse, which could be thought of as the main FUNCTION of the neuron. But the DENDRITES are the parts which assess whether the neuron has been stimulated enough to fire the axon, which is another fundamental function of some neurons. And the BODY (soma) of the neuron is very much a 'main' part of the neuron, because without it the neuron would die.
