Please read the entire thing.
Describe neurotransmitters, their function, and impact on behavior. Discuss one neurotransmitter in detail describing the effect it has on our bodies and connection with disease. Discuss the importance of biology for understanding behavior.
My response below:
Neurotransmitter, what are they? well as described in (Psychology by Carol Wade and Carol Mavis 8th edition) it is a chemical substance that is released by a transmitting neuron(a cell that conducts electrochemical signals; the base unit of the Nervous system, also called a nerve cell.)at the synapse and that which alters the activity of a receiving neuron. They are Chemical messengers.
Neurotransmitter makes it possible for one neuron to excite or inhibit another. They are chemical messengers located in the brain, spinal cord, peripheral nerves and certain glands. Through their effects on specific nervous circuits, they can affect moods, memory, and well being. This transmitter is a naturally occurring chemical that transmit messages between nerve cells(neurons). There are hundreds of substances known to being transmitters in our bodies and the number keeps growing.. Neurons speak to one another, in many cases from muscles to glands. When a cell is stimulated a change in electrical potential occurs between the inside and the outside of a cell. The result is a brief change in electrical voltage that produces electrical impulses, changes then occur in the receiving neurons membrane and the effect is either excitatory( a shift in positive direction) or a inhibitory(a shift in the negative direction) The messages that reaches the final direction depends on the rate in which the individual neutrons are firing, how many are firing and what types are firing.
Neurotransmitters is naturally produced by amino acids, with the help of vitamins and minerals. We get amino acids, vitamins and minerals from the foods we eat, and if we are not getting these in the right quantity, deficiency occurs, and over time disease and illness associated with a low level of neurotransmitter occurs. Abnormal levels of neurotransmitter are implicated in some common illnesses and diseases, including, but not limited to ADHD, Anorexia, Bulimia, Depression, High blood pressure, High cholesterol, Diabetics and Parkinson and Alheizmer Diseases.
One very important Neurotransmitter is called Serotonin
This Neurotransmitter called serotonin is thought to be implicated in many brain disorders. Its role in emotional mood swings, depression, and anxiety disorders are well established in the medical field. These important neurotransmitter containing serotonin are restricted to the area of the mid brain, with its nerve endings extending over much of the central nervous system . Serotonin is synthesized from amino acids(Amino Acids are fundamental pieces of protein, there are 20 different ones, some essential and non-essential. The essential ones are essential for your metabolism, growth and health and must be attained from foods) and as mentioned is located mainly in nerve pathways of the mid brain, cerebral cortex and the spinal cord.
In addition to mood control, it has been linked to sleep disorders, schizophrenia, blood pressure and hormonal activity. Outside of the brain it also affects the gastrointestinal and cardiovascular systems. It is said that too little of this serotonin can lead to anger control and suicide issues. The drug Prozac and a glass of warm milk before bed increases the levels of serotonin.
We know that Biology is the science of living things or the study of life. How we act and behave comes directly from our physiological make up. Because of the many sequences of unfolding genetically behaviors from before birth through our senior years Biology and behavior is then a "cause and effect" relationship. Genes with its many challenges and failings are passed on through our lineage which affects individuals at different times in their lives . After mapping and identifying the DNA pool , scientist are now recognizing and working on certain types of genes to eliminate certain diseases and behavior patterns.
During our daily lives we have hundreds of stimulus that affects our biological, behavior clock using all of our senses(sight, hearing, feeling, taste and smell). Many of these go on simultaneously in our busy lives , and we never recognize or pay them too much attention. all in one way or another impacts our behavior, but only when we have a discriminative stimulus( touching something hot) is only when we acknowledge and respond, implementing a behavior change.
As a living breathing entity, how do we interpret emotions and perceptions, things that physically affects us and our behavior?, science and psychologist are still looking for that answer. Mostly then Biology has explained a wide variety different living phenomenon, including its impact on our behavior patterns.
YOUR COMMENT (4-5 SENTENCES ON THE CONTENT):
What interested you?
What are some things you didn't agree with?
Overall writing (not to much emphasis)?
Attenetion Deficit Htperactivity Disroder there are doing study shows that Neurotransmitter not connecting I believethey believe this could a cause of ADHD
You use capitals within sentences where they are not needed.
One of the authors is Tavris rather than Mavis.
Titles of books or magazines need to be in italics or underlined.
You need to match singular and plural subjects with verbs ("Neurotransmitters is...." "Neurotransmitter, what are they?" "...hundreds of stimulus...." "...scientist are...." and others). Be consistent in using "neurotransmitters" in plural, unless you are discussing the one specific neurotransmitter.
Many of your sentences are too long. They need to be separated into different sentences (e.g., "Amino Acids are fundamental pieces of protein, there are 20 different ones, some essential and [others] non-essential.").
Your problems with writing distract the reader from the information you are trying to present.
In the future, if nobody is available to proofread your work, you can do this yourself. After writing your material, put it aside for a day — at least several hours. (This breaks mental sets you might have that keep you from noticing problems.) Then read it aloud
as if you were reading someone else's work. (Reading aloud slows down your reading, so you are less likely to skip over errors.)
If your reading goes smoothly, that is fine. However, whereever you "stumble" in your reading, other persons are likely to have a problem in reading your material. Those are "stumbles" indicate areas that need revising.
Once you have made your revisions, repeat the process above. Good papers often require many drafts.
I hope this helps. Thanks for asking.
Your response to these questions would rate a low B in my class. I must ask you to remove this posting, because some of my students have found it and copied it. They got zeroes on the assignment. Also, you are in violation of copyright by posting the questions.
