A large United States Naval Air Station, the first in the United States, is located southwest of Pensacola (near Warrington); it is the base of the Blue Angels flight demonstration team and the National Naval Aviation Museum. The main campus of the University of West Florida is situated north of the city center.
The ends of the axons are clusters of terminal buttons. Terminal buttons are small knobs that secrete chemicals called the neurotransmitters. These chemicals serve as that messengers that may activate neighboring neurons.hare to: 1  Inside the Brain: What is a Neurotransmitter? 2  Reuptake Inhibitor: A Psychological Definition Reuptake inhibitors increase the amount of available chemicals in the brain, called neurotransmitters. 3  What Chemical Causes Depression? 4  What Does Marijuana Do to the Brain? 5  What Is a Neurotransmitter? 6  Why Is Nicotine Addictive?
Your brain is made up of billions of nerve cells. They communicate by releasing chemical messengers called neurotransmitters. Each neurotransmitter is like a key that fits into a special lock, called a receptor, located on the surface of nerve cells. When a neurotransmitter finds its receptor, it activates the receptor's nerve cell. The nicotine molecule is shaped like a neurotransmitter called acetylcholine. Acetylcholine and its receptors are involved in many functions, including muscle movement, breathing, heart rate, learning, and memory. They also cause the release of other neurotransmitters and hormones that affect your mood, appetite, memory, and more. When nicotine gets into the brain, it attaches to acetylcholine receptors and mimics the actions of acetylcholine. Nicotine also activates areas of the brain that are involved in producing feelings of pleasure and reward. Recently, scientists discovered that nicotine raises the levels of a neurotransmitter called dopamine in the parts of the brain that produce feelings of pleasure and reward. Dopamine, which is sometimes called the pleasure molecule, is the same neurotransmitter that is involved in addictions to other drugs such as cocaine and heroin.
