In the nervous system there are two superfamlas of receptors for neurotransmitters. According to the number of trasmenbranarias regions that they possess to receive information. There is a selectivity of a family of receptors for a single neurotransmitter that is only possible by connecting to the appropriate membrane. The first family Main article: Receptor coupled to protein G
Share the fact of having seven transmenbranal regions, using the G protein for and making use of the second messenger.
The second familyShare the common molecular makeup of each member with five transmenbranal regions and with several versions of each receiver configured around an ion channel. Ejemplo simple
Each neurotransmitter is like a key and each receiver is like the lock there are 5 notches and 7.
