Want this question answered?
The nervous system is composed of many cells called neurons, these are essentially the functional units of the nervous system. ?Neurotrnasmitters are chemical messengers that are sent from one neuron to another neuron. ?So basically they are messangers communicating from one neuron to the next. ?Some neurotransmitters are excitatory which act to help activate a neuron, some neurotransmitters are inhibitory and act to reduce excitement of a neuron. ?Many many neurotransmitters will act on a neuron at a given time and the sum total will result in either an excitation or inhibition of that neuron. ?Examples of neurotransmitters include GABA, glutamate, serotonin, dopamine, acetylcholine, histamine, ?glycine, epinephrine, norepinephrine, melatonin, substance P, and many more!

Cocaine and heroin don't act on synapses. Heroin acts on the opioid receptors of neurons. Cocain acts primarily on the dopamine receptors. These are different structures on the surface on neuron cells. They work sort of like switches. Chemicals like heroin flip the switch on or off, affecting the behavior of the neuron. This is a very simplified explanation to this question.

like your brain, it send certain signals to the designated parts, which in turn responds to the signals and act appropriately.
The type of nerve cells are called neuroglia.
I have never heard of the term 'transmission zone' (which may be someone's personal name for what I'm about to explain) but neurons send their chemical signals across what is known as a synapse, the region where the axon of one neuron meets up with another neuron (most often a dendrite). The space between these two neurons (the non-neuron space in the synapse) is called the synaptic cleft. Through this space, neurotransmitters pass through and act on the receiving neuron once they reach it.
