The synaptic knob contains $..........$.

Assertion : The chemical stored in the synaptic vesicles are termed as neurotransmitters.
Reason : Synaptic vesicles release these chemicals in the synaptic cleft.

Assertion : Transmission of nerve impulse across a synapse is accomplished by neurotransmitters.
Reason : Transmission across a synapse usually requires neurotransmitters because there is a small space, i.e., $synaptic \ cleft$, that separates one neuron from another.

Branched ends of nerve cells are called telodendria,which establish functional contact with other nerve cells. This connection is called:

What happens if $GABA$ is released at the synapse?

$A$ nerve impulse is transmitted from one neuron to another through the junctions called
