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 are the sources of stimulation that start a nerve impulse?
An impulse begins when a neuron is stimulated by another neuron or by the environment.
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
When the neuron is sussiciently stimulated this process and triggers the action potential?
depolarization
A neuron that is excited to subthreshold is said to be?
It has become activated/stimulated.
When the neuron is sufficiently stimulated this process occurs and triggers the action potential?
depolarization
What are the sources of stimulation that start a nerve impulse?
An impulse begins when a neuron is stimulated by another neuron or by the environment.
What begins when a neuron is stimulate by another neuron in its environment?
A nerve impulse
What is an unstimulated neuron?
It is a neuron that is at its resting potential, not stimulated by input from other neurons.
A neuron will generate action potentials when it?
A neuron will generate action potential when it is stimulated by a neurotransmitter.
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?
motor unitUnit
When the neuron is sussiciently stimulated this process and triggers the action potential?
depolarization
A neuron that is excited to subthreshold is said to be?
It has become activated/stimulated.
When cholinergic receptors are stimulated they?
sodium ions enter the postsynaptic neuron.
