It results from the opening of voltage-gated sodium ion channels, causing an influx of sodium ions (influx of positively-charged ions), depolarizing the neuronal membrane.

Nerve messages are called an impulse. Synapses are the space between two axons.
A nerve impulse typically starts at the dendrites of a neuron, where it receives signals from other neurons or sensory receptors. These signals are then transmitted down the axon of the neuron to the axon terminals, where they can communicate with other neurons or target cells.
Myelinated A fibers have the fastest speed of impulse propagation among nerve fibers.
The duration of a nerve impulse is very short, typically around 1-2 milliseconds. This rapid transmission allows for quick communication between neurons and helps to coordinate various body functions.

Yes, an action potential is needed for a nerve impulse to occur.

It is called a nerve impulse.
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.

Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
