What is the role of the neurotransmitter in the nervous system
A
speeds up the transmission of nerve impulses
B
receives information from other neurones
C
transmits impulses from the cell body to neurones
D
facilitates the transmission of nerve impulses in one direction
Explanation: 

Detailed explanation-1: -Neurotransmitters are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.

Detailed explanation-2: -Because neurotransmitter storage vesicles and receptors are present in one location, impulse transmission occurs only in one direction.

Detailed explanation-3: -The receptor molecules on the second neuron can only bind to the specific neurotransmitters released from the first neuron. The binding of neurotransmitter to the receptors stimulates the second neuron to transmit an electrical impulse along its axon . The signal therefore has been carried from one neuron to the next.

Detailed explanation-4: -The nerve impulse travels in the form of electrical charge from axon end to the synapse. Here, the electrical impulse is converted to the chemical impulse in the synaptic cleft. Further this nerve impulse flows from synaptic cleft to dendritic tips, converting the chemical impulse to electrical impulse.
