Wendy Christien - 3 Feb 2022 - Neurotransmitters

Neurotransmitters are chemical messengers or molecules that the nervous system uses to send messages throughout the body. Neurotransmitters influence neurons and can either initiate an inhibitory, excitatory, or modulatory action on the neurons.
Neurons are information carriers, and they use electrical impulses and
chemical signaling to transmit information to the various areas of the brain as well as to the rest of the nervous system.
