The cell membrane becomes more permeable to the sodium potassium ions.
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.

False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
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.

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.
Any topical neuron can be stimulated through the pressure (whether it be little or a lot) of touch. In response to a topical neuron being stimulated it can cause a chain reaction effect to the neurological mapping of the area being affected.
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.
If a neuron was stimulated simultaneously at both ends, the action potential generated in the middle would effectively cancel out due to the opposing electrical currents flowing towards each other. This phenomenon is known as antidromic collision and may prevent the neuron from conducting signals efficiently.
The synapse between pre synaptic and post synaptic neuron. Here the acetylcholine is released. It is destroyed by the enzyme acetylcholinesterase in milliseconds, once the impulse is passed to the post synaptic neuron
A neuron that is excited to subthreshold is said to be depolarized. This means that the neuron's membrane potential has become less negative, bringing it closer to the threshold potential needed to generate an action potential.
