Neurotransmitter

What are Neurotransmitters? The functions of the brain rely heavily on a complex system of communication. The brain’s process of communication is supported by a series of cells called Neurons which submit chemical charges known as Neurotransmitters. Neurons are the foundation for the brain’s functions and consist of three basic parts such as the Cell Body, Dendrites and Axons. The chemical transmissions from Neurotransmitters are the product of messages being communicated from one Neuron to the next through the axon of the cell. This message is better known as an Action Potential, which is “an excitation that travels along an axon at a constant strength”. (Kalat, 1992)Action Potential can be caused by sodium ions traveling through the axon…

After viewing the video on Neurotransmitters, in explaining how neurotransmitter transmission occurs, I would first tell my client that our brain has what’s called a reward system. When we use drugs, eat, gamble, shop, etc. the chemicals in our brain gives us a reward system that makes us feel good. Through our nerve cells in our brain, messages are delivered through what’s called neurotransmitters. Our nerve cells, also known as neurons are not connected and the messages must be sent from one…

Specialized chemicals known as neurotransmitters carry signals across synapses. Each neurotransmitter is linked with particular effects depending on the distribution of each neurotransmitter among the brain's numerous functional areas. For example, dopamine is highly concentrated in regions that regulate motivation and feelings of reward (Dombeck, 2002). A neurotransmitter's impact also depends on whether it stimulates or decreases activity in its target neurons. Drugs make their effects by…

Acetylcholine was the first neurotransmitter discovered. It is the neurotransmitter associated with learning, thought, arousal, and activation of muscles. Acetylcholine enables movement by sending messages from motor neurons to muscles. This neurotransmitter is also linked with memory. Those with low acetylcholine can have Alzheimer’s disease. Alzheimer’s disease is associated with problems in memory, language, and thinking. For example, those with Alzheimer’s will slowly forget people’s names…

The nucleus accumbens is the release sight for the neurotransmitter dopamine, a nature chemical in the central nervous system. When released in standard quantities, it assists in critical brain functions. Like most neurotransmitters, dopaminergic signaling entails an equilibrium between dopamine release and the re-uptake by presynaptic nerve terminal. Under specific circumstances, a stimulus will promote the release of dopamine into the synapse. Dopamine transporters will then remove the…

Welcome to the most hyped club of the century! Here you’re welcome to hit it off at the dance floor or cool down in the chill room. Intensify you club experience with 3,4- methylenedioxymethamphetamine (MDMA) or what is better known as ecstasy. Let’s get down to business and talk about the popularity of this drug, along with its destructive nature. Zooming into the brain, neurons release chemical substances that are called neurotransmitters. These chemicals are responsible for daily life and…

then the axon carries the action potential to its terminal buttons, and finally a neurotransmitter will be released. The neurons will send information, so it can travel down the axon and away from the body of the cell. The main goal of an action potential is to have a thought be created by the end of the process. A depolarizing current is created when an action potential explodes with electrical activity. It is important to remember that the transferring of ions across and through the axon walls…

The knowledge regarding the biological causes of depression is somewhat rudimentary compared to other illness due to the lack of thorough knowledge regarding the complexities of the human brain. However, the monoamine theory, hypothesizes that a predisposition to depression can occur in individuals whose serotonin, norepinephrine, and dopamine have been depleted (Bunney & Davis 1965; Delgado 2000; Hirschfield 2000) Serotonin, norepinephrine, and dopamine are neurotransmitters responsible for…

There is no doubt that dopamine plays a huge role on cognitive learning, but what would happen if there was a lack of dopamine. Dopamine is a neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system (271). Neurotransmitters are very important because they are what connect everything. They allow our body and brain to work properly. If there is lack or tolerance of neurotransmitters there is many effects it can have on cognitive abilities, but how…

Noradrenaline narrows blood vessels, which increases blood pressure. ii. It also increases blood glucose levels, which circulates fatty acids. iii. Clinically, noradrenaline maintains blood pressure in septic shock, or even shock. b. Acetylcholine can act as a neuromodulator because it is the main neurotransmitter of the parasympathetic nervous system. According to Khetrapal (Hons), cholinergic signaling of acetylcholine can release glucose, and it can regulate sleep patterns, and other…
