PATHOLOGY

Detailed explanation-1: -Neurotransmitter – A chemical released from a neuron following an action potential. The neurotransmitter travels across the synapse to excite or inhibit the target neuron. Different types of neurons use different neurotransmitters and therefore have different effects on their targets.

Detailed explanation-2: -The enzymes needed for transmitter synthesis are synthesized in the neuronal cell body and transported to the nerve terminal cytoplasm at 0.5–5 millimeters a day by a mechanism called slow axonal transport.

Detailed explanation-3: -Neurotransmitters: the chemical messengers that communicate between adjacent neurons; release of neurotransmitters from one neuron will either help depolarize or hyperpolarize (increase the magnitude of the charge) the adjacent neuron, making an action potential either more or less likely to occur in the next neuron.
