Neurotransmitters on Physical and Mental Behavior Essay

Our physical and mental behaviour is controlled by what is called Neurotransmitters. These neurotransmitters are described as free drifting chemicals in our encephalon transmit signals in the synapse. a junction that permits a nerve cell to go through electrical signals to other cells. In this paper I will place four major neurotransmitters. such as the Dopastat. acetylcholine. gamma aminobutyric acid and glutamate. Plus. I will analyse their map. and measure their impact on physical and mental behaviour. Neurotransmitters are stored in minute pouch called cysts located at the terminal of axons.

When an urge. reaches the terminal of the axon. the cysts discharge a neurotransmitter into a infinite between the cells. Besides. 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 happen which can suppress the cell from conveying the urge. ( scientific discipline. Jrank. org. 2011 ) The neurotransmitter Dopastat is stored in the synapse vass and is prevailing in the encephalon and the nervous system. Neurotransmitters on Physical and Mental Behavior Essay.

Besides. it is involved in musculus control and map. and when Dopastat degrees are low. it can do loss of motor. In add-on. it can do depression. dependences. cravings. irresistible impulses. low sex thrust. hapless attending and focal point. ( Integrative Psychiatry. 2011 ) The neurotransmitter acetylcholine carries nervus urges across an gap between the synapse. “Acetylcholine is besides one of the neurotransmitters that play a really of import function in memory” “its chief usag e if for control of centripetal input signals and muscular control.


It is besides known as a stimulatory neurotransmitter. Besides. when musculus nervousnesss release acetylcholine. it makes the musculuss contract. The drugs Tolterodine. SSRIs and cannabinoids that are used to handle the symptoms of multiple induration operate by modifying the operation of acetylcholine. ( Acetylcholine. org. 2011 ) Sometimes the encephalon experiences an surplus of nervous tenseness and emphasis. this can be caused by an copiousness of epinephrine.

To compensate the extra epinephrine. the encephalon produces a neurotransmitter called GABA which is the most of import inhibitory neurotransmitter in the cardinal nervous system. It helps the nerve cells mend after transmittal. and decrease anxiousness and emphasis. GABA is a important temper modulator and has repressive effects upon the nervous system. ( NeuroGenesis. 2011 ) Glutamate is the major excitatory neurotransmitter in the encephalon which is necessary for larning and memory. When glutamate is at a low degree it can take to weariness and hapless encephalon map.

But. when glutamate is increased it can do decease to the nerve cells in the encephalon.Neurotransmitters on Physical and Mental Behavior Essay.  “Dysfunction in glutamate degrees are involved in many neurodegenerative diseases such as Alzheimer’s disease. Parkinson’s. Huntington’s. and Tourette’s. High degrees besides contribute to Depression. OCD. and Autism. ” ( Integrative Psychiatry. 2011 ) Neurotransmitters plays a critical function in our physical and mental behaviour. and eating a healthy diet and taking the proper addendum can assist our encephalon and physical being to work decently.

‘Virtually all functions in life are controlled by neurotransmitters.’

Neurotransmission are the body’s regular chemical messengers which transfer data from one neuron to another. Thus, they are unquestionably one of the building blocks of behaviour. Neurotransmitters are potent chemicals that adjust various physical and responsive processes such as psychological performance, emotional conditions and agony reaction. Thence, relations between neurotransmitters and the brain chemicals have an unfathomable impact on general health and wellbeing. However, like hormones, if neurotransmitter levels are insufficient these stimulating and rousing signals will be absent; thus, an individual may feel very stressed, blunt and unambiguously out of control. Simply, the method by which these messages are sent is called neurotransmission. The neurotransmitters are kept in the neurons’ terminal buttons. In addition, neurotransmitters have many effects on human behaviour; as it regulates sleep, modifies mood and thought processes, controls ability to focus, concentrate, and remember things, and controls the appetite centre of the brain. They have been displayed to have a variety of distinct effects on human behaviour. Indeed, neurotransmission triggers behaviour, in the same way as it activates mood, memory, sexual arousal, and mental illness. Furthermore, neurotransmitters play a huge role in everyday life and functioning. Scientists do not yet know exactly how many neurotransmitters exist, but more than 100 chemical messengers have been recognized.Neurotransmitters on Physical and Mental Behavior Essay.  The effect of acetylcholine on memory and muscle contraction; the effect of serotonin on sleep and emotion and the effect of noradrenaline on depression and alertness will all be discussed,

The brain needs neurotransmitters to regulate many necessary functions, including:

  • heart rate
  • breathing
  • sleep cycles
  • digestion
  • mood
  • concentration
  • appetite
  • muscle movement

The nervous system controls the body’s organs, psychological functions, and physical functions. Nerve cells, also known as neurons, and their neurotransmitters play important roles in this system.


Nerve cells fire nerve impulses. They do this by releasing neurotransmitters, which are chemicals that carry signals to other cells.

Neurotransmitters relay their messages by traveling between cells and attaching to specific receptors on target cells.

Each neurotransmitter attaches to a different receptor — for example, dopamine molecules attach to dopamine receptors. When they attach, this triggers action in the target cells.

After neurotransmitters deliver their messages, the body breaks down or recycles them.

Experts have identified more than 100 neurotransmitters to date.

Neurotransmitters have different types of action:

  • Excitatory neurotransmitters encourage a target cell to take action.
  • Inhibitory neurotransmitters decrease the chances of the target cell taking action. In some cases, these neurotransmitters have a relaxation-like effect.
  • Modulatory neurotransmitters can send messages to many neurons at the same time. They also communicate with other neurotransmitters.

Some neurotransmitters can carry out various functions, depending on the type of receptor that they are connecting to.

The following sections describe some of the best-known neurotransmitters. Neurotransmitters on Physical and Mental Behavior Essay.


Acetylcholine triggers muscle contractions, stimulates some hormones, and controls the heartbeat. It also plays an important role in brain function and memory. It is an excitatory neurotransmitter.

Low levels of acetylcholine are linked with issues with memory and thinking, such as those that affect people with Alzheimer’s disease. Some Alzheimer’s medications help slow the breakdown of acetylcholine in the body, and this can help control some symptoms, such as memory loss.

Having high levels of acetylcholine can cause too much muscle contraction. This can lead to seizures, spasms, and other health issues.

The nutrient choline, which is present in many foods, is a building block of acetylcholine. People must get enough choline from their diets to produce adequate levels of acetylcholine. However, it is not clear whether consuming more choline can help boost levels of this neurotransmitter.

Choline is available as a supplement, and taking high doses can lead to serious side effects, such as liver damage and seizures. Generally, only people with certain health conditions need choline supplements.


Dopamine is important for memory, learning, behavior, and movement coordination. Many people know dopamine as a pleasure or reward neurotransmitter. Neurotransmitters on Physical and Mental Behavior Essay. The brain releases dopamine during pleasurable activities.

Dopamine is also responsible for muscle movement. A dopamine deficiency can cause Parkinson’s disease.

A healthful diet may help balance dopamine levels. The body needs certain amino acids to produce dopamine, and amino acids are found in protein-rich foods.

Meanwhile, eating high amounts of saturated fat can lead to lower dopamine activity, according to research from 2015. Also, certain studies suggest that a deficiency in vitamin D can lead to low dopamine activity.

While there are no dopamine supplements, exercise may help boost levels naturally. Some research has shown that regular exercise improves dopamine signaling in people who have early stage Parkinson’s disease. Neurotransmitters on Physical and Mental Behavior Essay.
