Answer: b) neurotransmitter; synapse

Explanation:

Synapse:

the nerve impulse is transmitted from one neuron to another through the junctions called synapses.

A synapse is formed by the membrane of the presynaptic neuron and postsynaptic neuron, which may or may not be separated by a gap called the synaptic cleft.

There are two types of synapse: electrical synapse, chemical synapse.

Chemical synapse:

The membrane of the presynaptic and postsynaptic neurons are separated by a fluid-filled space called the synaptic cleft.

The chemical synapses are the commonest type of synapses consisting of bulbous expansion of nerve terminal, called the synaptic knob, lying in close proximity to the membrane of the postsynaptic neuron.

Neurotransmitters:

The cytoplasm of the synaptic knob contains tiny, round sacs called synaptic vesicles. Each synaptic vesicle contains as many as 10,000 molecules of neurotransmitter substance.

The neurotransmitter are the chemicals which are involved in the transmission of nerve impulses across the chemical synapse.

These chemicals do not participate in the transmission of nerve impulses at the electrical synapse.
