A Receptor is a physiological term for the part of a nerve that receives and reads chemical signals (neurotransmitters) from other nerves to transmit the electrical signals that transfer information through the brain and nervous system. This happens in an area of the nerve called the synapse which is essentially where one neuron ends and another begins. If you're not familiar with this, please do review the definition of synapse.

This sounds complicated but it is a lot like a relay race where a stick or baton (neurotransmitter) is passed from one runner (synapse) to another (receptor) until it gets to the end of the race (the brain).
