Neurotransmitters on Physical and Mental Behavior Essay

Our physical and mental behavior is controlled by what is called Neurotransmitters. These neurotransmitters are described as free floating chemicals in our mental capacity transmit signals in the synapse, a junction that permits a neuron to pass electrical signals to other cells. In this paper I will commit four major neurotransmitters, such as the dopamine, acetylcholine, gaba and glutamate. Plus, I will analyze their function, and evaluate their impact on physical and mental behavior. Neurotransmitters are stored in minute sac called vesicles located at the end of axons.When an impulse, reaches the end of the axon, the vesicles discharge a neurotransmitter into a space between the cells. Also, neurotransmitters spread across the synapse and attach to receptors in the receiving cell that are designed for the neurotransmitter. Furthermore, the cell may be stimulated or the opposite may occur which can inhibited the cell from infection the impulse. (science. Jrank. org, 2011) The n eurotransmitter dopamine is stored in the synapse vessels and is prevalent in the brain and the flyaway system.Also, it is involved in muscle control and function, and when dopamine levels are low, it can ready press release of motor. In addition, it can cause depression, addictions, cravings, compulsions, low sex drive, poor attention and focus. (Integrative Psychiatry, 2011) The neurotransmitter acetylcholine carries nerve impulses across an opening between the synapse. Acetylcholine is also one of the neurotransmitters that play a very important role in memory its main use if for control of sensory input signals and muscular control.It is also known as a stimulatory neurotransmitter. Also, when muscle nerves release acetylcholine, it makes the muscles contract. The drugs Tolterodine, SSRIs and cannabinoids that are used to treat the symptoms of multiple sclerosis operate by modifying the functioning of acetylcholine. (Acetylcholine. org, 2011) Sometimes the brain experiences a n excess of nervous tension and stress, this can be caused by an abundance of adrenaline.To counterbalance the additional adrenaline, the brain produces a neurotransmitter called GABA which is the most important inhibitory neurotransmitter in the primeval nervous system. It helps the neurons mend after transmission, and decrease anxiety and stress. GABA is a significant mood modulator and has inhibitory effects upon the nervous system. (NeuroGenesis, 2011) Glutamate is the major excitatory neurotransmitter in the brain which is necessary for learning and memory. When glutamate is at a low level it can lead to weariness and poor brain function.But, when glutamate is increased it can cause death to the neurons in the brain. Dysfunction in glutamate levels are involved in many neurodegenerative diseases such as Alzheimers disease, Parkinsons, Huntingtons, and Tourettes. High levels also contribute to Depression, OCD, and Autism. (Integrative Psychiatry, 2011) Neurotransmitters plays a vital role in our physical and mental behavior, and eating a healthy diet and taking the proper supplement can help our brain and physical being to function properly.
