From this, he concluded that nerves send messages by releasing chemicals. These chemicals atomic number 18 the neurotransmitters that are synthesized by nerve cells, which are derived from the foods we eat.

The neuron then transpor ts them to axon terminals. From there, an action potential causes their release from the terminals. at a time released, they attach to receptors and alter the activity of the postsynaptic neuron. When the molecules are separated pee the receptors, they may become inactive chemicals. They may be taken back into the presynaptic terminal to be used again, a...If you want to originate a full essay, order it on our website: OrderEssay.net
