Statement A: The chemical stored in the synaptic vesicles are termed as neurotransmitter.
Statement B : Synaptic vesicles release these chemicals in synaptic cleft.

Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons, where they stimulate the muscle fibres. These chemicals stored in the synaptic vesicles (or neurotransmitter vesicles) are released at the synaptic cleft. The release is regulated by a voltage-dependent calcium channel. Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the cell.
