Neurotransmitters are chemicals made by neurons and used by them to transmit signals of information from one neuron to another. They are powerful chemicals that regulate a variety of physical and emotional processes such as mental performance, emotional states and pain response. Virtually all functions in life are controlled by neurotransmitters. They are the brain's chemical messengers. Interactions between neurotransmitters, hormones, and the brain chemicals have a profound influence on overall health and well-being. When our concentration and focus is good, we feel more directed, motivated, and vibrant. Unfortunately, if neurotransmitter levels are inadequate these energizing and motivating signals are absent and we feel more stressed, sluggish, and out of control. There are a diverse number of neurotransmitters and other transmitter substances that function like a neurotransmitter. For example, acetylcholine is the only neurotransmitter between motor neurons and

Unformatted text preview: voluntary muscles. Therefore, it mediates all voluntary movement. Every move that we make depends on acetylcholine released to our muscles by motor neurons. When acetylcholine is released, it causes depolarization of the muscle membrane and will also cause the muscle to contract.Therefore, if the effects of acetylcholine were not limited, then our muscles would continue to contract without the ability to relax and would result in generalized muscle cramping, spasms, and seizures. Also, because the muscle cell membrane would not be able to repolarize for renewed contractions, it would lead to generalized paralysis. Acetylcholine also contributes to attention, arousal, and memory. This is why memory loss seen in Alzheimer's disease is associated with an inadequate supply of acetylcholine in certain areas of the brain. The drug treatments for the disease amplify acetylcholine activity and can slightly slow the progress of the disease....
