The arrival of a neural impulse at the axon terminal causes the release of ________ from the _____________.
xeze [42]

The arrival of a neural impulse at the axon terminal causes the release of neurotransmitter from the synapse.

<h3>What are neurotransmitters?</h3>

A neurotransmitter is indeed a signaling molecule that a neuron secretes to affect some other cell all over a synapse.

The cell that receives the signal, which could be any major body part or target cell, could be another neuron or a gland or muscle cell.

An action potential travels the length of an axon and causes neurotransmitter release at the synapse.

The neuron can interact with other neurons thanks to the action potential and subsequent transmitter release.

Thus, the correct answers are neurotransmitter and synapse respectively.
