<h3>What are Neurotransmitters?
</h3>
Neurotransmitters, which are organic compounds, play a major role in the language that neurons use to communicate with one another and with their final targets. Following electrical stimulation, these substances are produced and act on their particular receptors to start a response that can be as simple as a muscle contraction or as extremely complex as starting a chain reaction that eventually changes how the organism behaves. Neurotransmitters can have multiple functions; depending on where they act, they can be neuromodulators or, in some cases, neurohormones.

However, this is a stereotype, or an over-generalization about a particular category of people. Therefore, it does not actually reflect what all individuals in this group are like. The fact that she does not like Mark is an example of prejudice, as she is basing her conclusion on a preconceived idea she has of him, without taking the time to actually get to know him.
