Document Summary

Caffeine locks into the adenosine receptors, and instead of feeling sleepy, you feel wide awake. Not just caffeine -> all drugs work like this. They resemble neurotransmitters that are supposed to do one thing, but the drugs do another and change the entire neural system. The destruction of the myelin sheath will most likely result in slower neural conduction. Most neurons in the brain are multipolar. Each neuron has a job to communicate with other neurons. Neurons use communication lines to communicate with each other with electric and chemical signals. Neurons look like they fuse together, but they don"t actually touch one another. A tiny gap between neurons called a synapse. Neurons have receptor sites that bond with the molecules, and when they do, special gates open which allow the flow of k+ and na+ through them. Inside the cell, there are ions (particles that have gained/lost electrons; +/- charged) Neuron is a semi-porous bag of fluid.
