signal-transducing molecules ("second messengers"messengers") in the post-synaptic cells (Cooper‚ Bloom and Roth 1996). Nine compounds -- belonging to three chemical families -- are generally believed to function as neurotransmitters somewhere in the central nervous system (CNS) or periphery. In addition‚ certain other body chemicals‚ for example adenosine‚ histamine‚ enkephalins‚ endorphins‚ and epinephrine‚ have neurotransmitter-like properties‚ and many additional true neurotransmitters may await discovery.
