The neurotransmitter which communicates between two neurons or between a neuron and a muscle is

The correct option is A Acetylcholine

• The neurotransmitter which communicates between two neurons or between a neuron and a muscle is acetylcholine.
• Acetylcholine is the organic compound that helps in the transmission of a nerve impulse from one neuron to another neuron.
• It functions in the peripheral nervous system and central nervous system both as an activator and inhibitor.
• In the peripheral nervous system, it causes skeletal muscles to contract. In the central nervous system, it inhibits the activation of the cholinergic system.
  Hence, the correct answer is option A.
