Detailed explanation-1: -The correct option is B. Neurotransmitter. Neurotransmitters are chemicals that are used to relay, amplify and modulate electrical signals between a neuron and another cell. They are released by vesicles present in the pre-synaptic knob of axon terminals .
Detailed explanation-2: -The presynaptic terminal is at the end of an axon and is the place where the electrical signal (the action potential) is converted into a chemical signal (neurotransmitter release).
Detailed explanation-3: -Answer and Explanation: The conduction of the nerve impulse down the axon is called as action potential. The nerve impulse is the form of electrical signals produced from the dendrites that get moves down the axon of the nerve cell to communicate with nearby neuron cell.
