Neurons of the brain are the basic building blocks of the nervous system. Neurons are found to be very close to one another forming a network of neurons. Neurons never touch and the way they communicate with each other is called a synapse. The synapse transmits information chemically between the neurons and cells they are trying to reach. Neurotransmitters are released from the neurons to activate receptors in other cells thought out the target cells. Drugs on the other hand interact with the receptors in the neurons and the target cells either activating them or blocking them, and then the drug has the effect the user wants. The neurotransmitters of the brain come in different variety and have different effects on the body. Acetylcholine is found in large quantities in the brain. It can have an inhibitory effect on the person causing euphoria and insomnia. Acetylcholine derived mostly from nicotine which is found in cigarettes. Catecholamines are neurotransmitters that include norepinephrine, dopamine, and epinephrine. These neurotransmitters control thought process. Cocaine for instance blocks the reuptake of dopamine and norepinephrine which cause increased feelings of agitation and paranoia. This caused by the simulation of non-catecholamine’s in the brain. Serotonin is a neurotransmitter that is found in most foods and other things we eat or drink. Serotonin results in the feeing of relaxation and is used for sleeping problems. The abuse of drugs can have a negative impact on the user; a change in the serotonin system can cause mood swings, insomnia, and aggressiveness. Endorphins is a neurotransmitter that helps in the blockage of pain, drug user abuse narcotics that do this because people who suffer from pain can have an easy way out of it. GABA is a neurotransmitter that is activated by alcohol which gives the user the effect of sedation, relaxation, and drowsiness. All of these transmitters are found naturally in our brains and drugs over simulate these transmitters giving the desired effect.…...

Neurotransmitters

...Neurotransmitters (NT) act as chemical messengers in the body. Specifically, they function to transmit signals from a neuron to a target cell across a potential space known as a synapse, or synaptic cleft. In effect, this allows one nerve cell to communicate with a second nerve cell. Some common neurotransmitters are acetylcholine, norepinephrine, dopamine, serotonin and gamma aminobutyric acid (GABA). Acetylcholine and norepinephrine are excitatory neurotransmitters while dopamine, serotonin, and GABA are inhibitory (Neurological Control, 2013). Neurotransmitters are molecules that act as messages in the nervous system in the human brain. These molecules range in complexity from the two-carbon transmitter glycine to large proteins. There are three major classes of neurotransmitters, and these include amino acids, amines, and peptides. For the next question, it is apparent that neurons can be described as the definite nerve fibers that exist in the body. This might be composed of one of three different types. These different types may include the interneurons nerves, afferent, and efferent nerves. Interneurons are part of the transfer of the indicators to the efferent neurons. These are a part of the motor nerve fibers that are the reason for the tightening of the muscles that are located in your arms to take your hand away from a surface that is hot. Afferent nerves are known to be receptors that are sensory and in charge of identifying stimuli. When detecting Stimuli it......

Synaptic Transmission

...influence how vesicles issue neurotransmitters, how neurotransmitters are cleaved/reuptake, they can hinder receptors, destroy receptors, and agonistically join to receptors which mimic the neurotransmitter. These are a few. Synapses are vital to the function of the nervous system. The most of the synapses in the nervous system in vertebrates are chemical synapses, where chemicals are utilized to transmit data between cells; although there are furthermore some electric synapses. The units in glossy musculature and cardiac musculature are electrically attached through gap junctions which are exceptionally large protein passages forming membrane pores expanding from cell to cell, endowing little substances and ions to move without coercion between the units Synaptic Transmission (Lytton 2002). But regardless, the most of the synapses in vertebrates are chemical. When a nerve impulse comes to a chemical synapse, neurotransmitters, which are pointer substances, are issued from the nerve terminal and diffuse to the membrane of the target cell. The unfastening of these passages can either stimulate or inhibit the electric undertaking of the target cell, transmitting to the cell nearer or farther away from its threshold grade for lifetime of an activity promise (Bear et al. After use, the neurotransmitter is either decimated or taken back up into the fatal from whom it came for reuse, and the synapse furthermore has means for degrading surplus neurotransmitters and eliminating......

Bipolar Unipolar

...manic symptoms, which are characterized by expansive mood, poor impulse control, grandiosity, rages, poor judgement, acting out in the areas of spending, sexual activity or violence. If you are manic, you are very social, have poor judgement due to the lack of impulse control, and the most dangerous part is you don't think you have a problem. The neurotransmitter system has received a great deal of attention as a possible cause of Bipolar Disorder. Researchers have known for decades that a link exists between neurotransmitters and mood Disorders, because drugs which alter these transmitters also relieve mood Disorders. Some studies hypothesize that a low or high level of a specific neurotransmitter such as serotonin, norepinephrine or dopamine is the cause. Others indicate that an imbalance of these substances is the problem, that a specific level of a neurotransmitter is not as important as its amount in relation to the other neurotransmitters. Still other studies have found evidence that a change in the sensitivity of the receptors on nerve cells may be the issue. In short, researchers are quite certain that the neurotransmitter system is at least part of the cause of Bipolar Disorder, but further research is still needed to define its exact role. Our genes hold all of our hereditary information and provide the “genetic code” that allows our bodies to function, but our environment can affect how our genes function. Half of our genes are inherited from our mothers and......

Genetics and Neurotransmitters in Autism

...Genetics and Neurotransmitters in Autism Abstract Autism is a developmental disorder characterized by the inability to relate and perceive the environment in a realistic manner. Brain development is affected in the areas of communication, cognition, and social interaction. There is a great variability in the disorder from person to person. There has been evidence to show that 60-90% of autism can be considered hereditary. Many researchers are attempting to understand the genetic determinism of the disease in order to pinpoint treatment. There are gene mutations and variants that have been discovered but due to the disease being heterogeneous and complex it is difficult to find consistency. There is also research indicating that the cause is neurological. The gap between genetics and neurology concerning autism is where the connection needs to be made in order to understand the disability wholly. Autism is a complex developmental disability as the result of a neurological disorder that affects the functioning of the brain. The onset of the disability is in infancy or early childhood with males being affected four times as often as females. Autism shows no racial, ethnic or social boundaries. The term Autism Spectrum Disorder (ASD) is used because it is covering a group of disabilities with similar features. There are three categories of autism spectrum disorder known as Autistic......

Neurotransmitter

...between neurons by the movement of chemicals or electrical signals across a synapse. The action potential has begun in the presynaptic neuron after neurotransmission takes position at a synapse. The binding process of neurotransmitters can trigger short term changes such as postsynaptic potentials also called membrane potential, or longer term changes depends on the stimulation of signaling cascades. It is essential for nerve impulses to assist in the propagation of signals in which they sent to and from the central nervous system (CNS) through efferent and afferent neurons. These signals coordinate both skeletal and cardiac muscles for functioning of organs for the continued existence of multicellular vertebrate organisms (cite). There are steps involve in the process of neurotransmission. First, the synthesis and storage of neurotransmitter takes place in vesicles so the cell is ready to go on to the next neuron after an action potential arrives at the nerve ending. Next, the action potential passes down the axon to initiate the release of neurotransmitter into the synaptic cleft (Leonard, 2003). Then, a receptor is activated in the postsynaptic membrane so that it can go on the signal and initiate another action potential. Inactivation of the neurotransmitter is when it transports back into the terminal to be recycled, degraded, or removed.

Drug Abuse Correlation to Child Abusee

...stress regulating hormones like cortisol and essential neurotransmitters that are involved in the addiction process, like epinephrine, dopamine, serotonin and GABA (Panzer, 2008). Miller, Kinnally, Ogden, Oquendo and Mann (2009) state in their study that survivors of abuse typically have lower than normal levels of important neurotransmitters like serotonin and dopamine, and GABA receptors are altered. When a child lives with ongoing stress like abuse, the brain stimulates the release of high levels of neurotransmitters and stress hormones (Panzer, 2008). Bremner (2005) discusses how the continuous release of stress hormones is one of the primary effects of child abuse. Since the abuse is ongoing, an abused child’s brain is releasing these neurotransmitters in excessive amounts on a continuous basis, which ultimately causes great damage. According to research Miller et. al. (2009) state that when neurotransmitters are stimulated excessively, over time as this continues, the neurotransmitters receptors become unresponsive or desensitized and eventually the brain no longer produces and releases adequate levels of neurotransmitters. This causes the child to become an adult who suffers with anxiety, depression, mood disorders, hyperactivity, cravings for carbohydrates, alcohol or drugs as well as impaired attention span (Kaufman et. al., 2000). The abused child is used to having high levels of those crucial neurotransmitters and is conditioned to engage in other behaviors......

Major Neurotransmitters

...Major Neurotransmitters Major Neurotransmitters While there are many, possibly more than fifty neurotransmitters already discovered by scientists, they have all been grouped into four major groups, they are acetylcholine, amino acids, monoamines, and neuropeptides. Neurotransmitters are chemicals inside the brain that communicate throughout the entire human brain and body. They relay signals between neurons, or nerve cells. Neurotransmitters are used by the brain to tell your body to do everything it does. They tell your heart to beat and your lungs to breathe. They can control your sleep, hunger and mood. It is possible to have an unbalanced or low level of certain neurotransmitters which will cause the human body to act in a vast variety of ways. There are many thing that can also effect why these neurotransmitters are not functioning correctly. Ach or acetylcholine, a biogenic amine, was discovered in 1920 by Otto Lewis during an experiment with a frog. According to The Concise Corsini Encyclopedia of Psychology and Behavioral Science, “ACh diffuses across the synapse, it binds to specific postsynaptic receptors to produce either a local excitatory effect or an inhibitory effect. Whether the postsynaptic neuron passes on the message by producing an action potential depends on the sum of the influences it receives from pre-synaptic neurons” (Neurotransmitters, 2004). Dopamine, nor epinephrine, epinephrine and serotonin are also......

Hormones and Neurotransmitters

...Hormones and Neurotransmitters Introduction to Psychology Brandi C. Guisto Hormones and Neurotransmitters Many communication pathways exist within human. The endocrine system and the central nervous system are the two main systems that regulate activities and transmit messages throughout various organs and glands in the human body. These systems use stimuli released from glands or neurons in order to adjust levels of chemicals to the body to ensure the body is performing properly (Huffman, 2013). The stimuli released from these systems are hormones and neurotransmitters. Hormones, though having some similarities to neurotransmitters, have very different and specific functions within the body. The endocrine system is made up of a network of glands which releases hormones directly into the bloodstream. This system helps to regulate long-term processes, like growth, on-going processes, like digestion, and bodily responses to emergencies. Each gland within the endocrine system releases a specific hormone to stimulate another gland. Parathyroid glands, which reside behind the thyroid, release the parathyroid hormone which keeps calcium levels in the blood stable. The pancreas secretes the hormones glucagon and insulin to increase or decrease glucose levels in the blood. The pineal gland secretes melatonin to assist in regulating sleep patterns. The hypothalamus, one of the staples of the endocrine system, secretes many hormones including anti-diuretic hormone and......

...special properties. Biological causes of clinical depression continue to be studied extensively. Great progress has been made in the understanding of brain function, the influence of neurotransmitters, and other biological processes, as well as how they may relate to the development of depression. Depression or anxiety causes individuals to have many changes in their behaviors. They tend to become isolated from their family, friends, or be social. Their eating patterns lead to either weight gain or loss; and sleeping patterns change where they either do not sleep or sleep excessively. They become agitated, irritable, and fatigue or have lack of energy. Biological psychology aims at finding the biological factor of depression. Selective serotonin reuptake inhibitors, (SSRI) have had a major impact on the field of biological psychology because it is the most commonly prescribed medication for the treatment of depression and other mental disorders including anxiety and obsessive disorder. The brain is the "command center" of the human body. It controls the basic functions of our bodies, our movements, and our thoughts and emotions. Researchers studying clinical depression tend to look at several aspects of brain function including the structures of the limbic system and the function of neurotransmitters within neurons. Those who research clinical depression have been interested in a particular part of the brain called the limbic system. This is the area of the brain that......

...10 Major Neurotransmitters Neurotransmitters are powerful chemicals that regulate numerous 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. Effects: Control the appetite center of the brain  Stimulates Corticotropin Releasing Factor, Adrenalcorticotropic Hormone, & Cortisol  Regulate male and female sex hormone  Regulates sleep  Modulate mood and thought processes  Controls ability to focus, concentrate, and remember things  The Mind Body Connection  The chemistry of our bodies can alter, and be altered by our every thought and feeling.

Six Major Neurotransmitters

...Six Major Neurotransmitters Joy Pachowicz PSY 350 Professor Alina Perez – Sheppe April 24, 2011 Introduction The purpose of this paper is to discuss the six major neurotransmitters. There are more than six neurotransmitters; but, in this paper, we will speak of six. To understand what neurotransmitters do; it will be necessary to do a small review of some other terms that will be included in explaining the six major neurotransmitters. Neurons are basic elements of the nervous system; and, unlike other cells, they can communicate with and transmit information to others cells over long distances. The neuron has a cell body and a cluster of fibers at one end that are called dendrites. The dendrites receive messages that other neurons communicate. (Feldman, p.61). The messages received by dendrites are carried by the axon, which is at the other end of the neuron. So, at one end of the neuron is the axon and at the other end are the dendrites. The dendrites receive chemical messages and the axons carry them to other neurons. (Feldman, p.61) The synapse is the space between two neurons where the axon of a receiving neuron communicates with the dendrites of the sending neuron. Neurotransmitters are the chemicals that carry messages across the synapse to dendrites of the receiving neuron. This paper will discuss six different neurotransmitters, their functions and how they affect mental illness and medical diseases. The first......

...Neurotransmitters are endogenous chemical that transmit signal from a neuron to a target all across the synapse. Neurotransmitter are package into synaptic vesicle culture beneath the membrane into axon terminal on the presynaptic side of a synapse neurotransmitter are synthesize from amino acids which are readily available from the diet and which require only a small amount of biosynthetic steps to convert Two types of neurotransmitter are amino acid which one molecule containing an amine groups a carboxylic acid group and a side chain. The key elements of amino acid are oxygen, carbon, hydrogen and nitrogen they are important biochemistry. Amino acid serves as the building block of protein which is linear chain of amino acid. Amino acid can be link together in varying sequences to form a vast variety of protein. Glutamic is a key compound in cellular metabolism in human dietary protein is broken down by digesting amino acid. Glutamic also play an important role in the body disposal of excesses or waste disposal. Neuron is an electronic excitable cell that process and transmits information by electrical and chemical signaling these signal sent by the neurotransmitter.
