Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are
